The Yahoo Adds Sheet — 5/12
These are Yahoo's top adds for the day — the largest day-over-day ownership_pct gainers across every Yahoo league, with the scheduled SPs filtered out so we're only looking at conviction adds, not matchup streams.
Top conviction: Trent Grisham (46% owned) is the cleanest buy on the board — a locked-in leadoff CF with a .222 xBA hiding under a .169 actual, 14.2% Barrel, and 50.9% HH%. The BABIP regression is coming and you want him before it lands.
#1 AVOID Henry Bolte
OF · ATH · 6% → 11% owned (▲ +5.0pp day-over-day)
Why he's being added: Pure speculative prospect add. Bolte sits at AAA RF #6 in the org and has been benched every single game day in the last week (5 bench days plus today). There's no transaction, no callup, no insider tweet, and no L14 line in the data block. With Lawrence Butler entrenched as the ATH starter and a stacked corner-OF group behind him (Brent Rooker, Carlos Cortes, Zack Gelof), there's no path to MLB at-bats right now.

Stream / Hold meter: Stream ▓▓░░░░░░░░ Hold · 20% — clear stream
Verdict: AVOID. No callup, no MLB role, no underlying signal — let someone else burn the FAAB on the name.
#2 AVOID A.J. Ewing
2B/OF · NYM · 2% → 7% owned (▲ +5.0pp day-over-day)
Why he's being added: Speculation tied to the Mets' OF injury picture — Juan Soto is on the IL and the corner depth thins out to MJ Melendez and Carson Benge — but Ewing himself is AAA LF #12 and has been benched all seven tracked days. No transaction, no L14, no tweet in the data block. This is a deep-dynasty name-recognition pop, not a real MLB callup.

Stream / Hold meter: Stream ▓▓░░░░░░░░ Hold · 20% — clear stream
Verdict: AVOID in 12-team mixed — no underlying signal in the data. Dynasty-only stash.
#3 HOLD Peter Lambert
SP · HOU · 34% → 36% owned (▲ +2.0pp day-over-day)
Why he's being added: Lambert is filling a rotation slot for an Astros staff missing Hunter Brown and Tatsuya Imai, and per MLB.com (May 11) Lance McCullers Jr. just had his right index fingernail pop off May 6 with his next start uncertain — meaning Lambert's runway just got longer. L14: 2G, 11.1 IP, 1.62 ERA, 7 K with sparkling Statcast (3.45 xERA, 73% Whiff). The Hold signal flags ERA > FIP, so more positive regression coming.

Stream / Hold meter: Stream ░░░░░░▓▓▓▓ Hold · 70% — leans hold
Verdict: HOLD. Rotation slot is real with McCullers/Brown/Imai all hurt, and the underlying ERA estimators back the surface line.
#4 HOLD Trevor McDonald
SP/RP · SF · 15% → 17% owned (▲ +2.0pp day-over-day)
Why he's being added: McDonald is the Giants' #6 starter filling the rotation slot opened by Logan Webb's IL stint. L14: 1G, 7.0 IP, 1.29 ERA, 8 K, with a supportive 3.73 xERA. He's behind Robbie Ray, Landen Roupp, Adrian Houser, and Tyler Mahle, so his leash is matchup-dependent — but the slot is his for now and the early peripherals back the add.

Stream / Hold meter: Stream ░░░░░▓▓▓▓▓ Hold · 60% — leans hold
Verdict: HOLD as long as Webb is out. If Webb gets activated, this becomes a STREAM-only play.
#5 AVOID Nolan Arenado
3B · AZ · 21% → 22% owned (▲ +1.0pp day-over-day)
Why he's being added: Slight name-recognition uptick, but the data doesn't support it. L14: 12G, .175 with 2 HR, 4 RBI. xwOBA is a meh .318 and Barrel% is just 7.9 — the contact profile of a fading vet. He's the 3B #1 in AZ so the job is his, but he's been benched both 05-11 and 05-12 after batting in the middle of the order all week. The Sell signal is real even with limited sample.

Stream / Hold meter: Stream ▓▓▓░░░░░░░ Hold · 30% — clear stream
Verdict: AVOID. The name still moves ownership, but the bat and the lineup card both say this is a corpse you don't need to buy.
#6 STREAM Lucas Giolito
SP · SD · 5% → 6% owned (▲ +1.0pp day-over-day)
Why he's being added: Giolito sits as SD's #3 starter behind Michael King and Griffin Canning, with Germán Márquez (IL, ETA Mid-late May) and Nick Pivetta (IL, ETA Mid-late May) both out per the injury report — clearing the deck for his innings. But there's no L14, no Statcast, and no signal in the data block, so this is a name-and-role add rather than a peripherals-driven one.

Stream / Hold meter: Stream ▓▓▓▓░░░░░░ Hold · 40% — leans stream
Verdict: STREAM in favorable matchups only. No L14 or Statcast signal in the data to justify a permanent slot.
#7 AVOID Michael Soroka
SP/RP · AZ · 59% → 60% owned (▲ +1.0pp day-over-day)
Why he's being added: Holding a rotation spot as AZ's #5 starter, but the L14 is rough — 2G, 9.1 IP, 8.90 ERA — and the 4.78 xERA agrees the underlying isn't pretty. The high K%/Whiff% rates look encouraging on paper, but the Sell signal flags small-sample noise and the ERA is real. With Corbin Burnes and Merrill Kelly both on the IL, his slot is secure, but the production isn't.

Stream / Hold meter: Stream ▓▓▓░░░░░░░ Hold · 30% — clear stream
Verdict: AVOID at 60% rostered — let the optimists hold him. STREAM-only against weak lineups.
#8 HOLD Brandon Marsh
OF · PHI · 38% → 39% owned (▲ +1.0pp day-over-day)
Why he's being added: Per @ToddZolecki (May 11), Marsh is leading MLB in hitting. L14: 12G, 20-48 (.416) with 5 RBI, 11 R, 1 SB — and the contact backs it (48.1% HH%, .346 xwOBA, .305 xBA). Yes, the Sell signal flags BABIP .388 as unsustainable, but the underlying .305 xBA means even after regression he's a useful OF3. He's locked in as PHI's LF #1.

Stream / Hold meter: Stream ░░░░░░▓▓▓▓ Hold · 70% — leans hold
Verdict: HOLD. AVG will drop from .416 but the Statcast says he's a real OF3, and he's still available in over 60% of leagues.
#9 HOLD Trent Grisham
OF · NYY · 45% → 46% owned (▲ +1.0pp day-over-day)
Why he's being added: The textbook buy-low. L14 .169 AVG looks ugly, but xBA is .222, xwOBA is .346, Barrel% is 14.2, and HH% is a monster 50.9. BABIP of .160 is flagged as unlucky-low — the Buy signal is screaming. He's the Yankees' CF #1 and has hit leadoff in 4 of his last 6 starts. This is one of the highest-conviction underlying signals on the entire board.

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 80% — strong hold
Verdict: HOLD — top buy-low on today's board. Leadoff Yankee CF with elite contact peripherals and unlucky BABIP. Add aggressively.
#10 HOLD Gregory Soto
RP · PIT · 39% → 40% owned (▲ +1.0pp day-over-day)
Why he's being added: Soto is locked in as the Pirates' CL #1 — sole name on the depth table — and the L14 is filthy: 5G, 0.00 ERA, 2 SV, 1 W, 6 K in 5.2 IP. Statcast supports the dominance (1.83 xERA). The Hold signal does flag ERA < FIP regression, so don't expect the goose egg to last, but the role is unchallenged and saves are saves.

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 80% — strong hold
Verdict: HOLD. Confirmed closer with elite ratios — add in any league still counting saves.
#11 HOLD Heliot Ramos
OF · SF · 46% → 47% owned (▲ +1.0pp day-over-day)
Why he's being added: Ramos is SF's LF #1 with Jerar Encarnacion and Bo Davidson both on the IL — no challenger to his playing time. L14: 12G, .269 with 1 HR. The Statcast is genuinely strong (.335 xwOBA, .280 xBA, 13.1% Barrel, 51.4% HH%). BABIP regression is coming (.382 flagged unsustainable), but the underlying batted-ball quality keeps him a useful OF.

Stream / Hold meter: Stream ░░░░░░▓▓▓▓ Hold · 70% — leans hold
Verdict: HOLD. Everyday LF with legit power contact — solid OF4/5 in 12-team.
#12 HOLD Luke Raley
1B/OF · SEA · 15% → 16% owned (▲ +1.0pp day-over-day)
Why he's being added: The Statcast pops — .390 xwOBA, .273 xBA, 21.7% Barrel, 53.3% HH%. L14 surface line is a sneaky-good 3 HR and 10 RBI in only 7 games despite a .173 AVG. He's SEA's RF #1 with multi-position eligibility (1B/OF). The bubbles show he sat 05-06 and 05-09, so there's some platoon usage to monitor, but the power profile is real.

Stream / Hold meter: Stream ░░░░░▓▓▓▓▓ Hold · 60% — leans hold
Verdict: HOLD for the power and dual eligibility. Watch the lineup card weekly — the bench days knock him down a notch.
#13 HOLD Aaron Ashby
RP · MIL · 30% → 31% owned (▲ +1.0pp day-over-day)
Why he's being added: Ashby is the Brewers' setup man behind closer Chad Patrick, and the L14 is elite: 4G, 7.2 IP, 1.25 ERA, 11 K, 2 W with a 2.28 xERA. The Whiff% and K% rates are otherworldly even on small sample. Holds + ratio anchor in 12-team, with handcuff value if Patrick falters.

Stream / Hold meter: Stream ░░░░░░▓▓▓▓ Hold · 70% — leans hold
Verdict: HOLD as a ratio play and Patrick handcuff — get in before he steals the 9th inning.
#14 Miguel Vargas (74% owned)
Briefly: over the writeup threshold but worth flagging. L14 .234 with 3 HR/8 RBI hides a juicy .403 xwOBA, .264 xBA, 15.9% Barrel, and the Hold signal flags BABIP .220 as unlucky-low. HOLD if rostered — this is a buy-the-dip month.
#15 HOLD JJ Bleday
OF · CIN · 13% → 14% owned (▲ +1.0pp day-over-day)
Why he's being added: Bleday's Statcast is the loudest underlying line in this list — .481 xwOBA, .343 xBA, 17.1% Barrel, 57.1% HH%. The L14 surface (.204, 3 HR, 8 RBI) hides serious damage. He's CIN's LF #2 / corner-OF flex, but he's started in the order every single game day in the last week (batting orders 2-7), so the playing time is functionally regular. BABIP .404 is flagged for regression, but the contact justifies a real-time add.

Verdict: HOLD. The xwOBA/xBA/Barrel combo is best-on-board territory and he's still under 15% rostered — this is the cheapest power-contact add on the wire today.
