Daily Waiver Report — Monday, May 4, 2026

Mark Vientos is sitting at 6% ownership with a .491 wOBA over the past seven days, two home runs, and a 94.5 mph exit velocity — and nobody is picking him up. That's the single biggest disconnect on today's board, and it anchors a Monday report loaded with actionable pitching arms and a few bats quietly building cases for roster spots.

Today's Top Adds

Adolis García (OF, PHI) — Add Now

García's strikeout rate has cratered from 26.7% over the past 30 days to just 9.5% in the last seven — the kind of plate-discipline shift that turns decent contact into real production. He's backing it up with a 94.0 mph exit velocity and 70.8% hard-hit rate across 21 plate appearances, posting a .292 wOBA that's already trending above his 30-day mark of .285. At 34% ownership, the window to grab him without a contested waiver claim is closing but still open. The strikeout reduction is the headline: a hitter who was fanning more than a quarter of the time is now making contact at an elite clip. Move now before a multi-homer game pushes him past 50%.

Watch List

Mitch Keller (SP, PIT)

Already 50% owned and climbing (+3% in seven days), Keller is flashing a 1.81 FIP with a strikeout rate that's risen from 20.7% to 23.1% over the past week. A 1.29 ERA across 7.0 innings is the surface stat, but the FIP says the underlying quality is even better. If he's available in your league, he shouldn't be for long.

Mark Vientos (1B/3B, NYM)

The numbers demand attention: a .491 wOBA, two homers, 94.5 mph exit velocity, and a 58.3% hard-hit rate — all in a solid five-game sample. His walk rate has jumped from 5.2% to 12.5%, suggesting improved selectivity at the plate, not just a lucky stretch. At 6% ownership with zero movement, this is a screaming market inefficiency. He's a priority add if you need corner-infield production.

Tanner Scott (RP, LAD)

A 54.5% strikeout rate in the last seven days. An 18 K/9. A 0.10 FIP. A 0.00 ERA. Scott is making hitters look helpless. Ownership has actually dropped 5% to 42%, which is baffling given the dominance. The strikeout rate is up from 26.2% over 30 days — this is a reliever on a completely different level right now. If he was dropped in your league, fix that immediately.

Matt Strahm (RP, KC)

Strahm has posted a 0.00 ERA with a 12 K/9 and a 30.8% strikeout rate that's jumped from his 30-day mark of 24.4%. The 2.43 FIP confirms the quality is real. At 16% ownership with no movement, he's an under-the-radar ratios stabilizer.

Brant Hurter (SP/RP, DET)

Just 2% owned, Hurter is an early-signal arm with a 2.10 FIP through 7.0 innings of workload this past week. The sample is thin, but the FIP is tantalizing. Worth a speculative add in deeper formats — monitor his next start for a fuller picture.

JJ Bleday (OF, CIN)

Bleday's .431 wOBA is powered by a 94.7 mph exit velocity and 62.5% hard-hit rate, plus a homer in the last seven days. At 1% ownership, he's a zero-risk flier in deeper leagues. The exit velocity is legit — you're betting on the batted-ball quality translating into counting stats.

Mitch Garver (C, SEA)

Catcher is a wasteland, which makes Garver's rising wOBA (.323 vs .272 over 30 days) relevant despite modest surface numbers. His strikeout rate dropped from 33.3% to 28.6% while his walk rate spiked from 15.6% to 28.6%. At 0% ownership, he's a free pickup for managers desperate at the position — though a 92.8 mph exit velocity and 50.0% hard-hit rate keep him firmly in watch territory.

Enyel De Los Santos (RP, HOU)

A 1.75 FIP and a strikeout rate climbing from 19.7% to 26.7% make De Los Santos a middle-reliever with sneaky value. The 2.43 ERA and 9.73 K/9 play in leagues that reward holds or bulk relief innings. Ownership has dipped 6% to 8% — the market is wrong here.

Carmen Mlodzinski (SP/RP, PIT)

Mlodzinski's 35.7% strikeout rate over the past seven days is a massive spike from 23.9% over 30 days. The 2.92 FIP across 5.7 innings of workload supports the breakout. Ownership has cooled 6% to 10%, creating a buying opportunity if the whiff rate holds.

Stream of the Day

No streaming-specific signals were detected today — the algorithm didn't flag any matchup-based short-term plays. If you need an arm for the week, Brant Hurter's 2.10 FIP at 2% ownership makes him the closest thing to a zero-cost streaming option on the board. Check back tomorrow for updated streaming targets as the weekly schedule fills in.

Ownership Movers

  • Mitch Keller (50%, +3%) — The only player on today's board with meaningful ownership momentum, and it's fully justified. A 1.81 FIP and rising strikeout rate make the move real.
  • Tanner Scott (42%, -5%) — Ownership is falling while he's posting an 18 K/9 and 0.00 ERA. This is a market correction waiting to snap back. Someone in your league dropped him — go check.
  • Enyel De Los Santos (8%, -6%) — Another reliever being shed while the underlying numbers improve. The 1.75 FIP says hold, not drop.
  • Carmen Mlodzinski (10%, -6%) — Similar story: ownership declining while K rate surges to 35.7%. The market is lagging the data.

Quick Hits

  • Tanner Scott's 54.5% strikeout rate is the highest on today's board by a wide margin — more than double his 30-day rate of 26.2%. That's borderline unprecedented for a reliever with this kind of workload.
  • Mark Vientos' wOBA jumped from .276 over 30 days to .491 over seven — a 215-point spike. Combined with dual eligibility at 1B/3B, he's the most undervalued bat in the report at 6% ownership.
  • Adolis García's strikeout rate dropped 17.2 percentage points week-over-week (26.7% → 9.5%). That's not a small adjustment — that's a mechanical or approach overhaul showing up in real at-bats across 21 plate appearances.
  • JJ Bleday leads all hitters on today's report with a 94.7 mph exit velocity at just 1% ownership — the widest gap between batted-ball quality and roster presence.
  • Three relievers on the watch list — Matt Strahm, Tanner Scott, and Carmen Mlodzinski — are all posting strikeout rates above 30%. If you're punting saves and chasing ratios, this is a rare week to stockpile high-K arms for free.
