The Adds Sheet — 6/8

Yahoo's top-15 waiver-wire adds for today (largest day-over-day ownership gains) are driven by a catcher surplus, a new Royals closer, and a few infielders whose contact quality is running ahead of their batting averages.

Top conviction ADD: Brandon Valenzuela — Toronto's de facto starting catcher while Alejandro Kirk is out, riding a .392 xwOBA over the last 14 days that sits well ahead of his surface line, a sign his contact quality is primed to pull his average up.

TL;DRSkim

Yesterday's coverage focused on Kody Clemens, Bryce Miller, and Will Vest. Today's board shifts the lens.

• TODAY'S ADDS — Brandon Valenzuela (C, TOR) with a .392 L14 xwOBA and elite contact; Alec Bohm (INF, PHI) with a low BABIP pointing to an AVG rebound; Curtis Mead (INF, WSH) with a .381 xwOBA and 16% L14 barrel rate.
• STREAMS THIS WEEK — Alex Lange (RP, KC) taking over the ninth inning as Lucas Erceg falters; Colton Cowser (OF, BAL) with a .314 L14 xwOBA after a demotion and recall.
• WATCH LIST — Jake Bauers (1B, MIL) with a .397 L14 xwOBA; Isaac Paredes (DH, HOU) with a .351 L14 xwOBA but a weak surface AVG (.169); Nick Gonzales (3B, PIT) with a .379 L14 xwOBA heading into BABIP regression.
• Bottom line: Valenzuela and Bohm are the clearest adds this week; Lange is the best stream-and-hold now that he's inheriting Kansas City's save chances.

ADD Brandon Valenzuela

C · TOR · 8% owned (▲ +1.0pp day-over-day)

Why he's being added: Valenzuela has been Toronto's everyday catcher since Alejandro Kirk fractured his thumb in early April, and he's settled in nicely. Over his last 14 days he's hitting .263 with 3 HR and 6 RBI while posting a .392 xwOBA — well ahead of his surface line — with a 13.6% barrel rate, 40.9% hard-hit rate, and 88.5 mph average exit velocity, all strong markers his batting average hasn't yet caught up to. Per @bnicholsonsmith (Jun 7), "Brandon Valenzuela back in there for his third start in a row even with a day game today. A three-hit game yesterday raised his season OPS to .795." The one caveat is that the runway is injury-driven; his role could tighten when Kirk returns.

Conviction meter: Watch ░░░░░░▓▓▓▓ Add · 72% — everyday catcher (while Kirk is out), xwOBA spike, contact quality unlocking

Verdict: ADD. Valenzuela is catching every day with elite contact metrics running ahead of his average, and the .392 xwOBA points to an AVG correction over the next 2–3 weeks. Just keep an eye on Kirk's return, which could cut into his playing time.

ADD Alec Bohm

3B · PHI · 37% owned (▲ +1.0pp day-over-day)

Why he's being added: Philadelphia's everyday third baseman is locked into the heart of the lineup and coming off a two-hit game in Sunday's win. Over his last 14 days he's batting .250 with 2 HR and 8 RBI — a line that understates his underlying quality. His L14 xwOBA (.286) is roughly in line with his season mark (.291), but the real signal is an unsustainably low .162 season BABIP. His recent contact has been solid (40% hard-hit, 93.1 mph EV), and Scott Lauber (Jun 7) noted Bohm and Bryson Stott delivering big hits in Sunday's win as the Phillies' offense started clicking. As his BABIP normalizes toward league average (~.300), his average should climb back above .250.

Conviction meter: Watch ░░░░▓▓▓▓▓░ Add · 65% — locked starter, BABIP-driven rebound signal

Verdict: ADD. Bohm is Philadelphia's full-time third baseman with a .162 BABIP that's unsustainably low; his contact quality supports a 20–30 point AVG rebound over the next two weeks.

ADD Curtis Mead

1B/3B · WSH · 27% owned (▲ +1.0pp day-over-day)

Why he's being added: Mead has carved out a steady, near-everyday role for Washington, splitting time between first and third base. Over his last 14 games he's slashing .244/.351/.472 with 4 HR and 11 RBI, and the power-contact signal is loud: a .381 L14 xwOBA, a 16.0% barrel rate, and a 44% hard-hit rate. His season .472 slugging reflects consistent gap-and-pull power, and a .239 season BABIP suggests he's been somewhat unlucky — meaning average gains could come on top of the power.

Conviction meter: Watch ░░░░▓▓▓▓▓░ Add · 60% — near-everyday role, elite L14 barrel rate, low BABIP unlocking

Verdict: ADD. Mead offers a dual unlock — elite power contact (.381 L14 xwOBA) plus a low .239 BABIP poised to regress upward — with 1B/3B eligibility adding roster flexibility.

ADD Alex Lange

RP · KC · 11% owned (▲ +2.0pp day-over-day)

Why he's being added: Lange has taken over as Kansas City's closer. After Lucas Erceg blew his sixth save and watched his ERA balloon past 6.00, manager Matt Quatraro announced a change to the ninth inning, and the hometown-native Lange — who'd been trending up for weeks after a rocky start — has stepped into the role, closing out the Twins on June 4. The surface peripherals still warrant some caution: a 4.33 season ERA and 4.68 xERA mark him closer to a league-average arm than a dominant one, and a 26.7% line-drive rate against suggests hitters have squared him up at times. But he's been excellent lately (a 0.00 ERA across 4.1 IP with 8 K over his last six games), and the role is what matters here — saves carry standalone value, and he's the guy getting them for now.

Last 7 days: 🟢• 06-01 🔴 B 06-02 🟢• 06-03 🟢• 06-04 🔴 B 06-05 🟢• 06-06 🔴 B 06-07

Conviction meter: Watch ░░░░░░▓▓▓░ Add · 68% — newly installed closer; hot L14 run; ratios are league-average, but the saves are real

Verdict: ADD. Lange is Kansas City's new ninth-inning option with Erceg pushed out of the role, and a reliever with save chances is worth grabbing — especially in saves-needy leagues. The underlying ERA may settle into the 4.00s, so temper the ratio expectations, but the save volume is the draw. The risk is the usual one for a shaky bullpen: if he stumbles, Daniel Lynch IV is the most likely next man up.

STREAM Colton Cowser

OF · BAL · 8% owned (▲ +1.0pp day-over-day)

Why he's being added: Baltimore's outfielder has heated up after a brief demotion and is back to full-time at-bats. Over his last 14 days he's hitting .317 with 4 HR and 10 RBI in 13 games — a sharp turn from his .171 mark entering the window. His L14 xwOBA (.314) is solid (season .309), and while his 8.3% L14 barrel rate is modest and the 78.6 mph EV and 20.8% hard-hit rate suggest he's still finding his swing, the results have been there. Per @masnRoch (Jun 7), Cowser is slotted in center field, giving him daily reps. The .171 season AVG on a .309 xwOBA looks unlucky, and the 13-game streak suggests the reset is taking hold.

Last 7 days: ⬜ 06-01 🟢7 06-02 🟢9 06-03 🟢7 06-04 🟢7 06-05 🟢• 06-06 🟢6 06-07

Conviction meter: Watch ░░░▓▓▓▓▓░░ Add · 55% — hot L14 streak, but season xwOBA modest, contact quality not elite yet

Verdict: STREAM. Cowser is riding a .317 L14 streak with full-time outfield at-bats, but his season xwOBA and contact metrics don't yet support a full-season commitment — stream him this week and reassess after the next 20 PA.

WATCH Jake Bauers

1B · MIL · 55% owned (▲ +1.0pp day-over-day)

Why he's being added: Milwaukee's everyday first baseman is showing elite contact metrics that contradict his .195 L14 average. Over 46 PA in the last two weeks he's posted a .397 xwOBA with a 9.1% barrel rate and a 63.6% hard-hit rate — elite marks that point to an imminent average correction. His season .365 xwOBA sits well above his .326 wOBA, another sign his surface line has lagged the underlying skill. The power is real (4 HR in 11 games), and as an everyday option his at-bats are secure.

Last 7 days: 🟢5 06-01 🟢5 06-02 🟢5 06-03 🟢• 06-04 🟢5 06-05 🟢5 06-06 🔴 B 06-07

Conviction meter: Watch ░░░░▓▓▓▓░░ Add · 55% — elite xwOBA and hard-hit rate, everyday role

Verdict: WATCH / ADD. Bauers' elite .397 L14 xwOBA and 63.6% hard-hit rate are real, and as Milwaukee's regular first baseman the playing time is there — he's a strong buy-low if the owner is scared off by the .195 average.

WATCH Isaac Paredes

DH · HOU · 47% owned (▲ +1.0pp day-over-day)

Why he's being added: Houston's primary DH is locked into daily at-bats, but his surface stats (.169 AVG) mask an encouraging skill profile. Over his last 14 days he's posted a .351 xwOBA with a 9.7% barrel rate and a 38.7% hard-hit rate — both above his season averages (.319 xwOBA, 6.9% barrel rate). The .169 AVG on a .319 xwOBA suggests poor BABIP luck. The caveat: at 44 PA, the sample is light and his recent 82.9 mph EV is below elite.

Last 7 days: ⬜ 06-01 🟢4 06-02 🟢4 06-03 🟢4 06-04 🟢4 06-05 🟢4 06-06 🟢4 06-07

Conviction meter: Watch ░░░░▓▓░░░░ Add · 40% — improving xwOBA but light sample, modest EV, AVG correction uncertain

Verdict: WATCH. Paredes is Houston's primary DH with an improving .351 L14 xwOBA, but the .169 AVG and soft 82.9 mph EV suggest the uplift is modest; look for another 20 PA of sustained contact before adding.

WATCH Nick Gonzales

3B/2B/SS · PIT · 29% owned (▲ +1.0pp day-over-day)

Why he's being added: Pittsburgh's primary third baseman — who also carries 2B and SS eligibility — is a locked-in starter with strong recent numbers (.301 L14 AVG, 2 HR, 10 RBI). The catch is his .375 L14 BABIP, which is unsustainably high, and his .379 L14 xwOBA against a .342 season mark suggests he's been riding above-normal luck. When the BABIP regresses toward .300, his average should fall 20–30 points, and his power (2 HR in 13 games) is below his season pace. An 11.1% L14 barrel rate is the one encouraging peripheral, but it doesn't fully offset the regression signal.

Last 7 days: ⬜ 06-01 🟢5 06-02 🟢4 06-03 🟢5 06-04 🟢1 06-05 🟢5 06-06 🟢2 06-07

Conviction meter: Watch ░░░░░▓▓░░░ Add · 35% — BABIP-driven hot streak, regression coming, high ownership

Verdict: WATCH. Gonzales is a locked starter with handy 3B/2B/SS eligibility, but his .375 L14 BABIP is unsustainable and points to 20–30 points of AVG regression; at 29% owned, hold what you have and don't chase.

WATCH Brandon Marsh

OF · PHI · 40% owned (▲ +2.0pp day-over-day)

Why he's being added: Philadelphia's left fielder is on a .400 L14 tear (16-for-40 with 4 HR over 11 games) and drawing All-Star buzz. But a .394 L14 BABIP is the engine behind the surge — batting-average luck more than a skill leap. His .421 L14 xwOBA towers over his .339 season mark, an 82-point gap, and the underlying numbers point to regression. Scott Lauber (Jun 7) praised him, but realistically his average should settle as the BABIP cools. At 40% ownership and peak buzz, he's a WATCH, not an add.

Last 7 days: ⬜ 06-01 🟢4 06-02 🟢4 06-03 🟢4 06-04 🟢7 06-05 🟢5 06-06 🟢4 06-07

Conviction meter: Watch ░░░░░░▓░░░ Add · 30% — BABIP-driven peak, regression likely, high ownership, sell signal

Verdict: WATCH. Marsh is riding an unsustainable .394 L14 BABIP; his .339 season xwOBA signals meaningful AVG regression ahead — he's a sell-high candidate at peak buzz, not an add.

WATCH Matthew Boyd

SP · CHC · 55% owned (▲ +1.0pp day-over-day) · IL15

Why he's being added: Chicago's left-hander is on the 15-day IL with a left knee injury (placed in early May, ETA around mid-June) and has no recent MLB sample. His season line (24.0 IP, 6.00 ERA, 1.29 WHIP) masks much stronger peripherals: a 4.20 xERA and 31.2% whiff rate suggest his ERA should drop once he's back, and his FIP (2.45) sits well below his ERA, pointing to bad sequencing and luck rather than poor stuff. With his return roughly a week away, he's not usable this week — stash him in an IL slot and activate when cleared.

Last 7 days: ⬜ 06-01 🔴 B 06-02 🔴 B 06-03 🔴 B 06-04 🔴 B 06-05 🔴 B 06-06 🔴 B 06-07

Conviction meter: Watch ░░░░░▓▓░░░ Add · 45% — strong xERA + FIP, but on IL with a mid-June ETA, not available this week

Verdict: WATCH. Boyd is on the 15-day IL (ETA mid-June) with strong underlying metrics (2.45 FIP vs. 6.00 ERA) that signal ERA regression downward; stash if you have IL space, but he's not active this week.

WATCH Mick Abel

SP · MIN · 12% owned (▲ +1.0pp day-over-day) · IL15

Why he's being added: Minnesota's depth starter has been on the 15-day IL since late April with a stale mid-May ETA and no recent sample. His season line (20.1 IP, 3.98 ERA, 1.57 WHIP) sits against a 5.07 xERA, meaning his ERA is currently better than his underlying performance — a sign of likely upward (worse) regression when he returns. His 10.2 K/9 is strong, but a 4.4 BB/9 is elevated and his fastball velocity is reportedly down from prior seasons. Without a confirmed activation date, he's a deep stash only.

Last 7 days: 🔴 B 06-01 🔴 B 06-02 🔴 B 06-03 🔴 B 06-04 🔴 B 06-05 🔴 B 06-06 🔴 B 06-07

Conviction meter: Watch ░░░░░░░░░░ Add · 20% — IL since late April, xERA > ERA (regression signal), velo down

Verdict: WATCH. Abel remains on the 15-day IL with a stale ETA; his 5.07 xERA signals his ERA should rise, and the velocity dip is a concern — he's a deep stash only, not a waiver add.

WATCH Jacob Latz

RP · TEX · 40% owned (▲ +1.0pp day-over-day)

Why he's being added: Texas's closer of record has been locked into high-leverage work, riding a strong run over his last 14 days (5.1 IP, 8 K, 1.76 ERA) with several save chances. The caution: his sparkling season ERA (1.90) is running well ahead of his 2.61 FIP, with a 2.31 xERA in between, suggesting his true level is more in the high-2.00s to low-3.00s. His Stuff+ (122) is elite and the save volume is real. Jeff Wilson (Jun 5) noted the Rangers will "try to limit how many two-inning saves he gets the rest of the season," hinting at usage that could cap his save chances.

Last 7 days: 🟢• 06-01 🔴 B 06-02 🔴 B 06-03 ⬜ 06-04 🟢• 06-05 🔴 B 06-06 🔴 B 06-07

Conviction meter: Watch ░░░░░▓▓▓░░ Add · 55% — locked closer role, ERA < FIP (regression signal), high ownership, usage capped

Verdict: WATCH. Latz is Texas's closer (40% owned) with a real save rate, but his 1.90 ERA sits well below his 2.61 FIP, signaling regression; the Rangers capping his two-inning saves may also limit opportunity volume.

WATCH Mauricio Dubón

SS · ATL · 35% owned (▲ +1.0pp day-over-day)

Why he's being added: Atlanta's shortstop is locked into the lineup with a mixed peripheral profile. Over 11 games in the last 14 days he's hitting .232 with 3 HR and 7 RBI, but his L14 xwOBA (.410) sits dramatically above his season .315, and his 11.5% L14 barrel rate and 34.6% hard-hit rate are both up from his season norms (6.0% and 29.5%), hinting at a real uptick. The catch: it's a 35 PA sample, and his 90.1 mph EV is solid but not elite. At 35% ownership he's already rostered in most 12-team leagues.

Last 7 days: ⬜ 06-01 🟢5 06-02 🟢5 06-03 🟢2 06-04 🟢5 06-05 🟢2 06-06 🟢2 06-07

Conviction meter: Watch ░░░░▓░░░░░ Add · 35% — L14 xwOBA spike to .410, but light sample, 35% owned, hold not add

Verdict: WATCH. Dubón is Atlanta's everyday shortstop with an encouraging .410 L14 xwOBA, but the 35 PA sample is light and he's already 35% owned; hold and monitor over the next 20 PA.

WATCH Matt Chapman

3B · SF · 69% owned (▲ +1.0pp day-over-day)

Why he's being added: San Francisco's third baseman is riding the momentum of a career day — two homers, including a grand slam, and a career-high 8 RBIs on June 5 vs. the Cubs — that finally put a loud result behind his improving underlying metrics. His recent hard-hit and barrel rates have climbed above his season baselines, and the gap between his contact quality and his overall line points to a continued rebound after a slow start. At 69% ownership, he's already rostered in most leagues, so this is more a hold-and-ride than a fresh add.

Last 7 days: 🟢6 06-01 🟢• 06-02 🟢5 06-03 🟢6 06-04 🟢7 06-05 🟢• 06-06 🟢7 06-07

Conviction meter: Watch ░░░▓▓▓▓░░░ Add · 52% — career game plus improving contact signal a turnaround; already widely owned

Verdict: WATCH. Chapman's career 8-RBI game and improving metrics point to a real turnaround, but at 69% ownership he's likely already rostered — a hold in most formats, a buy-low only if his owner is still anchored to the slow start.
