TL;DRSkim

Yahoo's biggest day-over-day ownership movers, sorted by confidence:

• TODAY'S ADDS — Jacob Gonzalez (recalled with Murakami, hamstring, sidelined a couple of weeks) carries a .646 SLG and 18 HR at Triple-A and should find at-bats as Chicago reshuffles its infield; Curtis Mead (xwOBA .374 against a .284 wOBA — a 92-point gap that screams positive regression) is the cleanest buy-low angle on the board as his role keeps growing.
• STREAMS THIS WEEK — Brooks Raley (setup man for an NL East contender, 1.27 ERA with a 124 Stuff+ to back it); Trevor Megill (Brewers closer, 0.00 ERA over the last 14 days, but a 3.12 xERA says the surface won't hold even as the 33.8% whiff rate keeps him in the leverage chair).
• WATCH LIST — Isiah Kiner-Falefa (.428 over 14 days on a .250 BABIP; the .317 xwOBA trailing a .353 wOBA means the surface is outrunning the skill), Jackson Holliday (.225 lately, a .286 xwOBA that doesn't help, and a .569 Triple-A OPS that reads like an adjustment period), Louis Varland (a 0.30 ERA that can't last; the 1.70 xERA and 60% grounder rate are real, but the correction will sting whoever's chasing it).
• Bottom line: Gonzalez is the clearest add today — a fresh call-up with genuine Triple-A power and a believable path to playing time. Mead is the sharpest buy-low for hitters if you've got a bench spot to be patient with.

ADD Jacob Gonzalez

2B/SS · CWS · 0% → 2% owned (▲ +2.0pp)

Why he's being added: The White Sox recalled Gonzalez on 2026-05-29, the same night Munetaka Murakami landed on the IL with a right hamstring issue that manager Will Venable expects to cost him a couple of weeks. Murakami plays first base and Gonzalez is an infielder — primarily a shortstop who's also logged time at second — so this isn't a clean one-for-one swap. The opening is more indirect: losing Murakami's bat forces Chicago to shuffle the infield, and that's where Gonzalez fits, with Vargas, Montgomery, Meidroth, and possibly Acuña or Antonacci all in the mix for reps. What earns him the call is the bat. After years of middling minor-league numbers, the 2023 first-rounder out of Ole Miss has broken out at Triple-A Charlotte this season, slashing roughly .308/.414/.646 with 18 home runs over 51 games. Jeff Passan reported the move tied directly to Murakami's absence. There's no MLB sample yet — this is a pedigree-plus-opportunity play — but the power is loud and the runway is real.

Watch ░░░░░░▓▓▓▓ Add · 75% — fresh call-up with Triple-A pop

Verdict: ADD. With Murakami down for multiple weeks, Gonzalez should carve out at-bats once Chicago sorts its alignment, and a 1.000-plus Triple-A OPS gives this the highest short-term ceiling on today's board. He won't slot in at first, but the infield versatility means the White Sox will find him a spot.

WATCH Brooks Raley

RP · NYM · 3% → 4% owned (▲ +1.0pp)

Why he's being added: Raley sits behind only the closer in New York's bullpen pecking order, working as a middle-inning leverage arm for a contender chasing every win. The season line is clean — 1.27 ERA across 21.1 innings, 10.1 K/9, 1.22 WHIP — and even a quieter last two weeks (3.21 ERA in limited innings) doesn't dent the bigger picture. A 124 Stuff+ confirms the arsenal is legitimate; the only caution is a 3.65 xERA hinting that some regression is coming, though a 26.0% whiff rate keeps the leverage value intact.

🔴 B 05-23 🟢• 05-24 🔴 B 05-25 🔴 B 05-26 🟢• 05-27 ⬜ 05-28 🟢• 05-29

Watch ░░░░▓▓▓▓░░ Add · 40% — hold-tier RP, not an add

Verdict: WATCH. The role is secure and the ERA is excellent, but at 3% ownership he isn't a needle-mover in standard formats this week, and the gap between his xERA and ERA points to a correction that could flip the narrative before long. Stash-worthy only in holds leagues.

WATCH Kirby Yates

RP · LAA · 8% → 9% owned (▲ +1.0pp)

Why he's being added: Yates is the closer in Anaheim, which means he owns the save chances — but the chances haven't materialized. Over the last two weeks he's thrown 4.2 innings with a 2.14 ERA, six strikeouts, and one save. On the season, that's a 3.68 ERA across 7.1 innings with a single save in eight outings, and his 3.53 xERA suggests the surface reflects skill more than luck.

Watch ░░░░▓▓░░░░ Add · 35% — the title without the save total

Verdict: WATCH. He has the job, but one save on the year and a modest workload mean the opportunities may not come often enough to roster him in standard leagues. The role is his; the volume is the question. Revisit when the save count starts climbing.

HOLD Jake Bauers

1B · MIL · 40% → 41% owned (▲ +1.0pp)

Why he's being added: Bauers is Milwaukee's everyday first baseman and has been swinging it well — a .275 average over the last 14 days (11-for-40, 2 HR, 9 RBI) on top of an .851 season OPS with eight homers in 182 plate appearances. The underlying read supports it: his .349 xwOBA tops his .318 wOBA, and a 52.8% hard-hit rate points to consistent contact.

Watch ░░░░░▓▓▓▓░ Add · 45% — solid starter, no fresh catalyst

Verdict: WATCH. He's a locked-in starter, but his 40% ownership already accounts for that, and there's no new spark — a decent-not-great two weeks in a small sample — to justify chasing the bump. A comfortable hold for current owners.

WATCH Shane Bieber

SP · TOR · 45% → 46% owned (▲ +1.0pp) · IL60

Why he's being added: Bieber opened the season on the 60-day IL with right elbow inflammation and is working back from it. He made his first rehab start on May 25 in the Florida Complex League, tossing two scoreless innings, and will build his pitch count from there. A former Cy Young winner, he's a clear rotation piece for Toronto once healthy — but the ownership bump is pure return speculation, since there's no playing-time runway this week.

Watch ░░░▓▓░░░░░ Add · 30% — IL stash, no activation date yet

Verdict: WATCH. The rehab has started, but he's still building up and weeks from a big-league return. Add him when the timeline tightens or a rehab assignment moves to the upper minors; today's speculation isn't actionable yet.

ADD Isiah Kiner-Falefa

2B · BOS · 1% → 2% owned (▲ +1.0pp)

Why he's being added: Kiner-Falefa is filling in at second base with Nick Sogard day-to-day (since 2026-05-29), giving him a short-term platoon role. He's been scorching over the last two weeks — .428 (12-for-28), a homer, six RBI, five runs, and a steal — though the underlying story is more measured: his .317 xwOBA trails his .353 wOBA. The redeeming detail is a .250 BABIP, well under the ~.300 league norm, which suggests some bad luck; if that normalizes, the skill should pull his average up rather than down. His starts tapered from six straight (05-23 through 05-27) to bench duty on the 28th and 29th — textbook platoon usage.

🟢9 05-23 🟢9 05-24 ⬜ 05-25 🟢9 05-26 🟢9 05-27 🟢7 05-28 🟢7 05-29

Watch ░░░░░░▓▓▓▓ Add · 70% — fill-in role, hot bat, BABIP rebound angle

Verdict: ADD. He's a direct fill-in with a verifiable hot streak and a credible buy-low wrinkle: the depressed BABIP against a respectable xwOBA means his average should hold up better than the skeptics expect. Grab him for the window while Sogard is out.

STREAM Trevor Megill

RP · MIL · 67% → 68% owned (▲ +1.0pp)

Why he's being added: Megill is Milwaukee's closer, and the recent form has been spotless — 0.00 ERA over 4.0 innings in the last 14 days with five strikeouts and two saves. The fuller season has been bumpier (4.74 ERA across 19.0 innings, six saves, six holds), but the 3.12 xERA and a 33.8% whiff rate argue the stuff is intact and the ERA is more mirage than reality. The one flag worth tracking: his fastball is down about 1.9 mph from last year, which is worth watching for either fatigue or decline.

Watch ░░░░░░▓▓▓▓ Add · 75% — closer role, elite peripherals, ERA regression cuts both ways

Verdict: STREAM. The job is his and the recent run is legit, but the xERA-to-ERA gap works in his favor here — the strikeout stuff should hold while the inflated season ERA comes down. Stream him for saves now; just keep an eye on that velocity dip.

WATCH Casey Schmitt

DH · SF · 74% → 75% owned (▲ +1.0pp)

Why he's being added: Schmitt is San Francisco's primary DH with full-time at-bats, and he's locked in lately: a .314 average over the last two weeks (17-for-54) with six homers, 13 RBI, nine runs, and a steal. The season profile holds up too (.861 OPS, four homers in 92 PA), and the skill matches the surface — his .360 xwOBA edges his .326 wOBA, with a 15.1% barrel rate and 44.5% hard-hit rate underpinning the power.

🟢3 05-23 🟢3 05-24 🟢3 05-25 🟢2 05-26 🟢3 05-27 ⬜ 05-28 🟢3 05-29

Watch ░░░░░░▓▓▓▓ Add · 60% — locked starter, hot bat, already widely owned

Verdict: WATCH. The role and the hot streak are both real, but at 74% ownership he's already rostered nearly everywhere in 12-team leagues. There's no waiver play here — he's a hold for the owners who have him, not an add.

WATCH Joshua Baez

OF · STL · 9% → 10% owned (▲ +1.0pp)

Why he's being added: Baez was recalled on 2026-05-29 to cover for Nathan Church (10-day IL), giving him a foothold in St. Louis's outfield. With no MLB sample yet, the read leans on his Triple-A line: .237/.317/.491 (.808 OPS) over 43 games, with 11 homers and 11 steals. The power-speed combo is intriguing, but the modest average and on-base mark suggest a useful fill-in bat rather than a must-add prospect.

🔴 B 05-23 🔴 B 05-24 🔴 B 05-25 🔴 B 05-26 🔴 B 05-27 ⬜ 05-28 🔴 B 05-29

Watch ░░░░░▓▓░░░ Add · 35% — fill-in role, modest Triple-A profile

Verdict: WATCH. He's covering for Church, but the Triple-A line doesn't yet scream big-league impact. Give it a game or two — if he comes out hitting, revisit, but today's profile doesn't justify a waiver claim.

ADD Curtis Mead

1B · WSH · 8% → 9% owned (▲ +1.0pp)

Why he's being added: Mead came to Washington in a late-March trade and started the year as a bench bat, but he's pitched his way into a steadily larger role — his recent starts have come mostly at third base, with first and second base eligibility in his back pocket too. The surface line over the last two weeks is ugly (.238, 10-for-42, 4 HR, 7 RBI), and that's exactly where the buy-low case lives: his .374 xwOBA towers over his .284 wOBA, and a .227 BABIP (well below the ~.300 norm) points to brutal luck rather than a real slide. A 45.5% hard-hit rate and 11.1% barrel rate say he's squaring the ball up; the hits should follow once the variance evens out.

🔴 B 05-23 🟢2 05-24 🟢3 05-25 🟢2 05-26 🟢3 05-27 ⬜ 05-28 🟢3 05-29

Watch ░░░░░░▓▓▓▓ Add · 75% — growing role, huge xwOBA-wOBA gap, BABIP rebound play

Verdict: ADD. This is the board's sharpest buy-low hitter — strong underlying contact buried under an unsustainable BABIP, attached to a role that's trending up rather than down. If you've got a bench spot and some patience, he profiles as a multi-week hold with average gains baked in as the luck corrects.

WATCH Louis Varland

RP · TOR · 72% → 73% owned (▲ +1.0pp)

Why he's being added: Varland is Toronto's closer, and the season has been historically good: a 0.30 ERA over 30.0 innings with 41 strikeouts (12.3 K/9), eight saves, and a 1.07 WHIP. The last two weeks (1.11 ERA, nine strikeouts, three saves) are more of the same. The skill is genuine — a 1.70 xERA and 28.3% whiff rate confirm the stuff, and a 60% grounder rate from his sinker-heavy mix limits the damage. The only certainty is that a 0.30 ERA can't last; even the 1.70 xERA implies the number climbs eventually.

🔴 B 05-23 🔴 B 05-24 🔴 B 05-25 🔴 B 05-26 🟢• 05-27 🟢• 05-28 🔴 B 05-29

Watch ░░░░░░▓▓▓░ Add · 65% — closer role, elite skill, but the ERA is a mirage

Verdict: WATCH. The role and the stuff are both elite, but the 0.30 ERA is statistical fiction — his own xERA points toward the mid-2.00s to low-3.00s as variance normalizes. At 72% ownership he's already widely rostered anyway: hold if you own him, but don't pay a premium chasing a number that's coming back to earth.

WATCH Spencer Horwitz

1B · PIT · 15% → 16% owned (▲ +1.0pp)

Why he's being added: Horwitz is Pittsburgh's everyday first baseman, and his last two weeks (.270, 3 HR, 6 RBI) look respectable on the surface. The peripherals tell a less flattering story, though: his .319 xwOBA trails his .353 wOBA, meaning the results are running ahead of the contact quality — the inverse of the Mead profile. A 5.8% barrel rate and 31.7% hard-hit rate are soft, which suggests the current average isn't built to last.

🟢5 05-23 🟢1 05-24 🟢1 05-25 🟢8 05-26 🟢1 05-27 🟢1 05-28 🟢• 05-29

Watch ░░░░▓▓░░░░ Add · 40% — full-time role, but the skill lags the surface

Verdict: WATCH. He plays every day, which justifies the small ownership tick, but the xwOBA-wOBA gap warns of negative regression — the soft contact points to a .240-.250 range as his realistic floor. Hold if you own him; there's no reason to chase the recent line from outside.

WATCH Jackson Holliday

2B · BAL · 42% → 43% owned (▲ +1.0pp)

Why he's being added: Holliday is Baltimore's everyday second baseman, but the start to his season has been rough — .217 over the last two weeks (7-for-31, 2 HR, 5 RBI) and a .644 OPS on the year. A recent Triple-A stint (.183/.269/.300, .569 OPS over 17 games) reinforces the sense that he's still adjusting to big-league arms. His .286 xwOBA is pedestrian and actually sits below his .348 wOBA, a sign that luck — not skill — has propped up even the modest surface numbers. This is a blue-chip prospect working through a real adjustment period, not a buy-low.

Watch ░░▓░░░░░░░ Add · 25% — everyday role, but the adjustment is ongoing

Verdict: WATCH. The job is his, but the combination of a tiny, weak MLB line and a sub-.200 Triple-A stretch says growing pains, not breakout. The ownership creep is speculation; the data argues for patience. Give him a few more weeks to find his footing — there's no catalyst to add today.

WATCH David Sandlin

SP · CWS · 6% → 7% owned (▲ +1.0pp)

Why he's being added: Sandlin made his 2026 debut on 2026-05-27, throwing 6.0 innings of one-run ball with four strikeouts and no walks for the win. It was a strong first look — his 1.37 xERA lines up neatly with the 1.50 ERA — but it's also just one start, and he appears to be more of a depth or emergency option than a rotation regular at the moment. With no Triple-A line to lean on, the entire case rests on that single outing.

Watch ░░░░▓░░░░░ Add · 30% — one debut, no rotation lock

Verdict: WATCH. The debut was impressive, but a single start carries almost no predictive weight, and there's no confirmation he's a fixture in the rotation. Wait for a second outing and some role clarity before biting — debut gems rarely repeat on cue.

WATCH Chase Meidroth

2B · CWS · 25% → 26% owned (▲ +1.0pp)

Why he's being added: Meidroth is Chicago's everyday second baseman, but he's slumping — .218 over the last two weeks (12-for-55, 2 HR, 8 RBI). His .729 season OPS is fine on its face, but the warning sign is a .373 BABIP that's wildly unsustainable; as it drifts back toward .300, the average is likely to follow it down. The underlying read agrees: his .301 xwOBA trails his .338 wOBA, meaning luck, not skill, has been doing the heavy lifting. The ownership bump looks like a bet on a bounce-back; the peripherals point the other way.

🟢5 05-23 🟢1 05-24 🟢5 05-25 🟢5 05-26 🟢1 05-27 🟢5 05-28 🟢5 05-29

Watch ░░░░░▓▓░░░ Add · 35% — everyday role, but a BABIP-driven correction looms

Verdict: WATCH. He plays every day, but the .373 BABIP is a flashing light, and the recent slump may be the front end of a longer correction rather than a blip. Don't add on the hope of a rebound — the underlying numbers suggest there's more downside ahead.

BOTTOM LINESkim

Jacob Gonzalez is today's clearest ADD — a fresh call-up tied to Murakami's multi-week hamstring injury, with legitimate Triple-A power and a believable, if indirect, path to playing time as Chicago reworks its infield. Curtis Mead is the sharpest buy-low for hitters: a .374 xwOBA strangled by a .227 BABIP, attached to a role that's expanding rather than shrinking — if you have bench depth, lock him in for the regression gains. Isiah Kiner-Falefa is a shorter play (only while Sogard is out), but the BABIP-and-skill story rhymes with Mead's. Everyone else on the board is either a speculative stash (Bieber, Varland), a streamer with obvious volatility (Megill, Raley), or a prospect still finding his footing (Holliday, Sandlin). In 12-team leagues: prioritize Gonzalez, then Mead if you've got the room, and skip the rest unless you're chasing hot hands in a shallow format.
