The Yahoo Adds Sheet — 2026-05-11

These are Yahoo's top adds for the day — the largest day-over-day ownership_pct gainers across every Yahoo league, with probable pitchers stripped out so what's left is real waiver conviction, not matchup streaming.

#1 AVOID Foster Griffin

SP/RP · WSH · 53% owned (▲ +2.0pp day-over-day)

Why he's being added: Griffin's surface line is gaudy — 2G, 13.0 IP, 12 K, 0.69 ERA, 1 W over the last two weeks — and a 49.0% K-rate plus 44.0% Whiff% are catching eyes. But the Statcast peripherals tell a different story: 4.03 xERA with a 2.67 ERA / 4.42 FIP gap that's begging to close. The signal flags Sell. He's the WSH SP #1 by depth, but on a non-contender with regression incoming.

Position depth:

Last 7 days: 🔴 B 05-05 🔴 B 05-06 🔴 B 05-07 🟢• 05-08 🔴 B 05-09 🔴 B 05-10 ⬜ 05-11

Stream / Hold meter: Stream ▓▓▓░░░░░░░ Hold · 30% — clear stream

Verdict: AVOID as a full-time hold. The ERA-FIP gap, low-leverage team context, and pedestrian xERA make him a sell-high in redrafts — stream the matchup if you must, but don't bank a roster spot on this profile.

#2 AVOID Brandon Marsh

OF · PHI · 35% owned (▲ +2.0pp day-over-day)

Why he's being added: @ToddZolecki noted on 2026-05-11 that Marsh is "leading MLB in hitting," and the L14 backs it up: 20-for-48 (.416) over 12 games with 11 R and a SB. Problem is the engine — xwOBA is only .346, xBA .305, Barrel% just 6.5. The signal is Sell: a .388 BABIP is doing all the work and AVG regression is baked in.

Position depth:

Last 7 days: 🟢5 05-05 🟢7 05-06 🟢5 05-07 🟢5 05-08 🟢6 05-09 🟢5 05-10 ⬜ 05-11

Stream / Hold meter: Stream ▓▓▓▓▓░░░░░ Hold · 50% — coin flip

Verdict: AVOID at the buy-in price his hot streak is creating. He's locked in as the LF #1, but the Statcast doesn't support a .416 AVG — the people selling Marsh right now are right.

#3 AVOID Michael McGreevy

SP · STL · 33% owned (▲ +2.0pp day-over-day)

Why he's being added: 2G, 12.0 IP, 12 K, 0.00 ERA, 2 W in the L14 — that's the entire pitch. But everything underneath is screaming red flag: 5.04 xERA, 20.0% Whiff, ERA (2.18) miles below FIP (3.84), and fastball velo is down 1.6 mph year-over-year. The signal is Strong Sell. He's the STL SP #3 by depth, so the rotation slot is real, but the profile isn't.

Position depth:

Last 7 days: 🔴 B 05-05 🔴 B 05-06 🔴 B 05-07 🟢• 05-08 🔴 B 05-09 🔴 B 05-10 ⬜ 05-11

Stream / Hold meter: Stream ▓▓░░░░░░░░ Hold · 20% — clear stream

Verdict: AVOID. Velo loss plus a 5.04 xERA is the worst combination in fantasy pitching — the next 3-4 starts will likely close the ERA-FIP gap hard.

#4 HOLD Xander Bogaerts

SS · SD · 63% owned (▲ +1.0pp day-over-day)

Why he's being added: The L14 line isn't sexy — 11-for-49 (.224) — but he's posted 3 HR, 7 RBI, 7 R, 3 SB across 13 games, and the underlying xwOBA (.345) and xBA (.274) suggest the AVG should climb. He's batted in the 2-6 hole every single game, locked in as the SS #1 with Cronenworth and Song both on the IL. The signal is Hold with light sample noise.

Position depth:

Last 7 days: 🟢6 05-05 🟢4 05-06 🟢5 05-07 🟢2 05-08 🟢5 05-09 🟢5 05-10 ⬜ 05-11

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 80% — strong hold

Verdict: HOLD. Multi-category producer (power + speed + lineup spot) at a thin position with zero competition for ABs — the .224 AVG will play up.

#5 HOLD Trent Grisham

OF · NYY · 45% owned (▲ +1.0pp day-over-day)

Why he's being added: This is the highest-conviction buy on the page. The L14 reads ugly — 10-for-54 (.185) — but the Statcast is elite: .345 xwOBA, 13.6% Barrel, 50.5% HH. The signal is Buy: BABIP .160 is comically unlucky and AVG should rebound hard. He's hit leadoff in 4 of the last 6 starts as the Yankees CF #1.

Position depth:

Last 7 days: 🟢1 05-05 🟢1 05-06 🟢7 05-07 🟢1 05-08 🟢8 05-09 🟢1 05-10 🔴 B 05-11

Stream / Hold meter: Stream ░░░░░░░░▓▓ Hold · 85% — strong hold

Verdict: HOLD — the strongest buy-low on the board. Leadoff barrels in the Bronx with a .160 BABIP and 50.5% HH is a HR-and-runs explosion waiting to happen.

#6 STREAM Aaron Civale

SP/RP · ATH · 21% owned (▲ +1.0pp day-over-day)

Why he's being added: 3G, 16.0 IP, 12 K, 0.56 ERA, 2 W is a fantasy owner's dream line, and he sits as the ATH SP #4. The catch: 4.15 xERA, 14.0% Whiff, and ERA-FIP gap (2.95 vs 4.05) flag a Sell signal. The strikeouts (26.0% K) are fine, not great, and the contact-management run is built on luck more than process.

Position depth:

Last 7 days: 🔴 B 05-05 🔴 B 05-06 🔴 B 05-07 🔴 B 05-08 🟢• 05-09 🔴 B 05-10 ⬜ 05-11

Stream / Hold meter: Stream ▓▓▓▓░░░░░░ Hold · 40% — leans stream

Verdict: STREAM in good matchups only. The role is locked but the underlying ERA is going to regress — ride it in 12-team for 2-3 starts, then re-evaluate.

#7 AVOID Grayson Rodriguez

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

Why he's being added: Pure name-recognition speculation. He's been on the 15-day IL since 2026-03-23 (shoulder) with a listed return of 2026-04-06 that's clearly come and gone. He's the LAA SP #15, role=backup, on the IL with no L14, no recent transaction, no tweet, and no game activity in 7 days.

Position depth: (not provided in data block)

Last 7 days: ⬜ 05-05 ⬜ 05-06 ⬜ 05-07 ⬜ 05-08 ⬜ 05-09 ⬜ 05-10 ⬜ 05-11

Stream / Hold meter: Stream ▓▓░░░░░░░░ Hold · 20% — clear stream

Verdict: AVOID — no underlying signal in the data. A stale IL stash with a missed ETA and a backup depth-chart slot isn't worth a 12-team roster spot.

#8 HOLD Luke Raley

1B/OF · SEA · 13% owned (▲ +1.0pp day-over-day)

Why he's being added: The AVG looks awful (4-for-23, .173) but the power is real — 3 HR and 10 RBI in just 7 L14 games. The Statcast is loud: .391 xwOBA, 22.0% Barrel, 54.2% HH. He's the RF #1 with multi-position eligibility (1B/OF), though the L7 bubbles show three bench days, which is the only real caveat.

Position depth:

Last 7 days: 🟢• 05-05 🔴 B 05-06 ⬜ 05-07 🟢7 05-08 🔴 B 05-09 🟢• 05-10 🔴 B 05-11

Stream / Hold meter: Stream ░░░░░░▓▓▓▓ Hold · 65% — leans hold

Verdict: HOLD for the power profile and dual eligibility. Watch the playing-time pattern — if the bench days keep stacking, drop to STREAM.

#9 STREAM Rico Garcia

RP · BAL · 31% owned (▲ +1.0pp day-over-day)

Why he's being added: 6G, 4.3 IP, 6 K, 0.00 ERA, 1 W, 2 SV — saves are why he's getting rostered. He's the BAL setup man behind closer Yennier Cano, but with Kittredge and Akin both IL'd, Garcia is the clearest backup save source. Statcast is loud but tiny sample (2.02 xERA, 95% K, 98% Whiff — yes, those are short-sample artifacts). Signal flags Sell on ERA-FIP gap (0.69 vs 2.97).

Position depth:

Last 7 days: 🟢• 05-05 🟢• 05-06 🔴 B 05-07 🔴 B 05-08 🔴 B 05-09 🟢• 05-10 🔴 B 05-11

Stream / Hold meter: Stream ▓▓▓▓▓░░░░░ Hold · 50% — coin flip

Verdict: STREAM for saves-plus chasers. He's the handcuff to Cano with 2 saves already banked — valuable in holds/SV+HLD formats, droppable elsewhere when Cano returns to full health.

#10 HOLD Aaron Ashby

RP · MIL · 28% owned (▲ +1.0pp day-over-day)

Why he's being added: L14 is dominant — 4G, 7.2 IP, 11 K, 1.25 ERA, 2 W — and he's the MIL setup man behind closer Chad Patrick. Statcast: 2.27 xERA, 98% K, 98% Whiff (short-sample but elite). Signal is Hold on sample size. The handcuff value here is real: Patrick is a converted setup himself and Ashby is the clear next-in-line.

Position depth:

Last 7 days: 🔴 B 05-05 🟢• 05-06 ⬜ 05-07 🔴 B 05-08 🟢• 05-09 🟢• 05-10 ⬜ 05-11

Stream / Hold meter: Stream ░░░░░░▓▓▓▓ Hold · 65% — leans hold

Verdict: HOLD — top closer-in-waiting candidate with strikeout upside that plays in any format. Worth the roster spot even before Patrick wobbles.

#11 HOLD Miguel Vargas

1B/3B · CWS · 71% owned (brief mention — over 70% ownership)

Vargas just clears the 70% threshold, so a quick note: he's the CWS 3B #1 batting 2nd-3rd daily, with 4 HR / 9 RBI in the L14, a .404 xwOBA, and a .220 BABIP flagging unlucky-low. The signal is Hold and the AVG should climb. If he's somehow still on your wire, grab him.

#12 HOLD JJ Bleday

OF · CIN · 13% owned (▲ +1.0pp day-over-day)

Why he's being added: Loud Statcast on a quiet-looking line. L14: 12G, 10-for-49 (.204), 3 HR, 8 RBI. The underlying: .481 xwOBA, .343 xBA, 17.1% Barrel, 57.1% HH. Yes, the .404 BABIP flags regression-down on AVG per the signal, but the contact quality is genuinely top-tier and the 2-hole lineup spot in Cincinnati's bandbox is locked in. He's the LF #1.

Position depth:

Last 7 days: 🟢• 05-05 🟢2 05-06 🟢7 05-07 🟢2 05-08 🟢2 05-09 🟢5 05-10 ⬜ 05-11

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 75% — strong hold

Verdict: HOLD. The 17.1% Barrel / 57.1% HH combo in GABP with a top-of-order lineup lock is a 25+ HR pace — ignore the .204 AVG noise.

#13 STREAM Nasim Nuñez

2B/SS · WSH · 13% owned (▲ +1.0pp day-over-day)

Why he's being added: Speed and lineup-spot stability. L14: 11G, 7-for-39 (.179), 0 HR, 4 RBI, 4 R, 4 SB. He's the 2B #1 batting 7-9 every game. The bat is empty — .283 xwOBA, .217 xBA, 0.0% Barrel, 18.3% HH — so this is a pure steals play in deeper formats.

Position depth:

Last 7 days: 🟢7 05-05 🟢9 05-06 🟢9 05-07 🟢8 05-08 🟢9 05-09 🟢9 05-10 ⬜ 05-11

Stream / Hold meter: Stream ▓▓▓▓░░░░░░ Hold · 40% — leans stream

Verdict: STREAM for SB chasers in 12-team. The 4-SB pace is real but 0.0% Barrel and bottom-of-order ABs cap him as a category specialist, not a full hold.

#14 HOLD Ryan Jeffers

C · MIN · 48% owned (▲ +1.0pp day-over-day)

Why he's being added: Catcher offense is scarce and Jeffers is delivering — 10G, 13-for-42 (.309), 2 HR, 7 RBI, 9 R, 1 SB. xwOBA .373 with 14.3% Barrel supports the surge, though the signal flags Sell on small sample. He's the C #1 with only Caratini behind him; lineup spots range 3-5.

Position depth:

Last 7 days: 🟢3 05-05 🟢5 05-06 🟢4 05-07 🟢3 05-08 🔴 B 05-09 🟢3 05-10 ⬜ 05-11

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 70% — strong hold

Verdict: HOLD as your C1 in 12-team. Heart-of-the-order ABs at a thin position with a .373 xwOBA is exactly the catcher tier you stop streaming.

#15 AVOID Ezequiel Duran

1B/2B/3B/SS/OF · TEX · 22% owned (▲ +1.0pp day-over-day)

Why he's being added: The multi-position eligibility (1B/2B/3B/SS/OF) is irresistible, and L14 looks fine: 12G, 12-for-47 (.255), 1 HR, 5 RBI, batting 2nd most days as the LF #1 with Langford on the IL. But the signal is Sell — .351 BABIP is doing the work, xwOBA is just .338, and Barrel% is a weak 6.9.

Position depth:

Last 7 days: 🟢5 05-05 🟢2 05-06 🟢2 05-07 🟢2 05-08 🟢2 05-09 🟢2 05-10 🔴 B 05-11

Stream / Hold meter: Stream ▓▓▓▓░░░░░░ Hold · 40% — leans stream

Verdict: AVOID as a hold — the role evaporates when Langford returns and the BABIP-driven line won't survive. The 5-position eligibility is the only reason to even consider a bench stash in deeper formats.
