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 (probable SPs excluded so we're looking at conviction adds, not matchup streams).
Top conviction HOLD: Trent Grisham (46% owned). He's batting leadoff in the Bronx six of seven days, posting a .346 xwOBA / 14.2% Barrel / 50.9% HH while his BABIP sits at an absurd .160 — every regression arrow points up.
#1 AVOID Henry Bolte
OF · ATH · 11% owned (▲ +5.0pp day-over-day)
Why he's being added: Pure prospect speculation. Bolte is the A's #6 RF on the AAA depth chart with no MLB call-up transaction, no L14 line, no Statcast, and no insider tweet in the data block. The OF picture in Oakland is fronted by Lawrence Butler with Carlos Cortes, Brent Rooker, Zack Gelof, and Colby Thomas already ahead of him for big-league reps. No clear catalyst in the data — likely speculative dynasty/stash add chasing a name.

Stream / Hold meter: Stream ▓▓░░░░░░░░ Hold · 20% — clear stream/stash
Verdict: AVOID in 12-team redraft — he's in Triple-A and not on the 26-man. Dynasty-only name with no near-term runway.
#2 AVOID A.J. Ewing
2B/OF · NYM · 7% owned (▲ +5.0pp day-over-day)
Why he's being added: Same story as Bolte — speculative prospect bid tied to Mets OF chaos (Juan Soto on the IL, Luis Robert Jr. not yet resumed baseball activities per New Baseball Media (May 11)). But Ewing is the #12 LF on the AAA depth chart, with MJ Melendez, Carson Benge, Tyrone Taylor, Austin Slater, and Andy Ibáñez all ahead. No call-up, no L14, no Statcast in the data — no clear catalyst beyond name recognition.

Verdict: AVOID — no underlying signal in the data for a 12-team add right now. Watchlist only.
#3 HOLD Peter Lambert
SP · HOU · 36% owned (▲ +2.0pp day-over-day)
Why he's being added: Lambert is filling a rotation slot opened by Hunter Brown (IL) and now reinforced by Lance McCullers Jr. losing his fingernail on May 6 ('Right index fingernail popped off May 6; next start uncertain' per MLB.com (May 11)). L14: 2G, 11.1 IP, 7 K, 1.62 ERA. Statcast is loud — xERA 3.45 with eye-popping 73% Whiff. He's a #6 rotation arm currently starting in Houston.

Stream / Hold meter: Stream ░░░░░▓▓░░░ Hold · 65% — leans hold
Verdict: HOLD in 12-team. ERA (3.27) sitting above FIP (1.93) means more good outings are coming, and McCullers's fingernail issue keeps the runway open.
#4 HOLD Trevor McDonald
SP/RP · SF · 17% owned (▲ +2.0pp day-over-day)
Why he's being added: McDonald is starting in place of Logan Webb (IL) — depth_chart shows him as starter (filling) at the #6 slot. L14: 1G, 7.0 IP, 8 K, 1.29 ERA, with an xERA of 3.73 backing it. Small sample but a real rotation foothold while Webb is out.

Stream / Hold meter: Stream ░░░░░▓▓░░░ Hold · 60% — leans hold
Verdict: HOLD as a back-end SP5/SP6 while Webb is out — the runway is real even if the long-term ceiling isn't.
#5 AVOID Nolan Arenado
3B · AZ · 22% owned (▲ +1.0pp day-over-day)
Why he's being added: Name-brand reflex add. The data does not support it: L14 is 7-for-40 (.175) with 2 HR and only a .318 xwOBA / .262 xBA / 7.9% Barrel / 27.7% HH — pedestrian Statcast across the board. He's the #1 3B in Arizona but was benched both 05-11 and 05-12 after starting the prior five days. Signal is Sell.

Stream / Hold meter: Stream ▓▓▓░░░░░░░ Hold · 30% — lean stream/avoid
Verdict: AVOID — over-the-hill veteran profile with mediocre xwOBA and back-to-back benchings. Don't burn FAAB on the name.
#6 AVOID Lucas Giolito
SP · SD · 6% owned (▲ +1.0pp day-over-day)
Why he's being added: Giolito sits as the Padres' SP #3 with Nick Pivetta and Germán Márquez both on the IL (Mid-late May ETAs per the curated report) — that role security is the only catalyst the data offers. No L14 line, no Statcast, no insider tweet, no transaction. Bench bubbles all week.

Verdict: AVOID for blanket adds — no underlying performance signal in the data block. Stream only in favorable matchups.
#7 AVOID Michael Soroka
SP/RP · AZ · 60% owned (▲ +1.0pp day-over-day)
Why he's being added: Rotation slot security with Merrill Kelly on the IL — Soroka is the #5 SP. But the L14 is ugly: 2G, 9.1 IP, 8.90 ERA, and xERA is 4.78 even with the 38% Whiff. Signal is Sell on light sample. Only one bubble in seven days.

Stream / Hold meter: Stream ▓▓▓▓░░░░░░ Hold · 35% — stream-only
Verdict: AVOID rostering — the xERA is north of 4.75 with an 8.90 ERA to match. Matchup stream only.
#8 HOLD Brandon Marsh
OF · PHI · 39% owned (▲ +1.0pp day-over-day)
Why he's being added: Per @ToddZolecki (2026-05-11): 'Brandon Marsh is leading MLB in hitting.' L14: 12G, 20-for-48 (.416), 11 R, 1 SB, with strong Statcast support (.346 xwOBA, 48.1% HH). He's batting 5-7 every game as the #1 LF. Caveat: signal is Sell — the .388 BABIP is unsustainable, so AVG is coming down even if the role is real.

Stream / Hold meter: Stream ░░░░░░▓▓▓░ Hold · 70% — clear hold
Verdict: HOLD — locked-in starting OF leading MLB in hitting with real HH support. Expect AVG to dip, but the runs/SBs/role keep him rosterable in 12-team.
#9 HOLD Trent Grisham
OF · NYY · 46% owned (▲ +1.0pp day-over-day)
Why he's being added: Today's highest-conviction buy. L14 line looks ugly (9-for-53, .169) but the Statcast says it's noise: .346 xwOBA, 14.2% Barrel, 50.9% HH, and a .160 BABIP that's flagged as unlucky low. Signal is Buy. He's the Yankees' #1 CF batting leadoff in 4 of the last 7 starts. Power is real (1 HR, 9 R, 1 SB in 13G even during the slump).

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 80% — strong hold
Verdict: HOLD — leadoff lock with elite barrel/HH metrics and a BABIP screaming for positive regression. Best value-add on today's board.
#10 HOLD Gregory Soto
RP · PIT · 40% owned (▲ +1.0pp day-over-day)
Why he's being added: Pittsburgh's CL #1 — closer of record. L14: 5G, 5.2 IP, 6 K, 0.00 ERA, 1 W, 2 SV. xERA 1.83. He pitched 3 of 7 days with two saves in the bag. Signal is Hold with a note that ERA (1.42) sits under FIP (2.52), so some climb is coming.

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 80% — strong hold
Verdict: HOLD — sole-owner closer role in Pittsburgh. Saves on a bad team still count; ride him until the role changes.
#11 HOLD Heliot Ramos
OF · SF · 47% owned (▲ +1.0pp day-over-day)
Why he's being added: Ramos is SF's #1 LF, batting in spots 1-7 throughout the week. L14: 12G, 14-for-52 (.269), 1 HR, .335 xwOBA, 13.1% Barrel, 51.4% HH. The signal flag warns the .382 BABIP will regress, but the underlying contact quality is legit and the role is locked.

Stream / Hold meter: Stream ░░░░░░░▓▓▓ Hold · 75% — clear hold
Verdict: HOLD — top-of-the-card everyday OF with 51% HH. Expect AVG dip, but counting-stat profile travels.
#12 HOLD Luke Raley
1B/OF · SEA · 16% owned (▲ +1.0pp day-over-day)
Why he's being added: Seattle's #1 RF. L14 only 7G but loud: 3 HR, 10 RBI on a .390 xwOBA, 21.7% Barrel, 53.3% HH. Multi-position eligibility (1B/OF) is a real bonus in 12-team. Bubbles show platoon flavor (only 4 of 7 days), which caps the floor.

Stream / Hold meter: Stream ░░░░░▓▓░░░ Hold · 60% — leans hold
Verdict: HOLD — elite Barrel/HH and multi-position eligibility outweigh the platoon usage. Worth the 16% ownership.
#13 HOLD Aaron Ashby
RP · MIL · 31% owned (▲ +1.0pp day-over-day)
Why he's being added: Setup role behind Chad Patrick in Milwaukee. L14 absolutely scorched: 4G, 7.2 IP, 11 K, 1.25 ERA, 2 W. xERA 2.28 with whiff/K rates that are extreme even in a small sample. Two vulture wins already in the 14-day window — those add up.

Stream / Hold meter: Stream ░░░░░░▓▓▓░ Hold · 70% — clear hold
Verdict: HOLD — high-leverage setup arm with WHIP-friendly skills and the next-man-up claim if Patrick wobbles. K/W upside on its own justifies the roster spot.
#14 Miguel Vargas — 74% owned (▲ +1.0pp)
3B/1B · CWS — Already widely rostered (>70%), no full writeup. L14 .234 / 3 HR / .403 xwOBA / .220 BABIP says he's hitting into bad luck and the bat is real. HOLD in any format that still has him available.
#15 HOLD JJ Bleday
OF · CIN · 14% owned (▲ +1.0pp day-over-day)
Why he's being added: Bleday is listed as a backup (corner-OF flex) but he's been starting in the 2-hole or 5-hole every game in the data window. L14: 12G, 3 HR, 8 RBI, with absurd Statcast — .481 xwOBA, .343 xBA, 17.1% Barrel, 57.1% HH. Signal flags the .404 BABIP as unsustainable, but the contact quality is elite enough to support real production even after regression.

Stream / Hold meter: Stream ░░░░░░▓▓▓░ Hold · 70% — clear hold
Verdict: HOLD — playing every day in the top of the order with the loudest Statcast profile on today's board. The backup label is misleading; the lineup card says everyday.
