Daily Waiver Report — Sunday, May 31, 2026

Reid Detmers has spiked his strikeout rate to 43.8% over the past seven days — up from 31.3% over the prior month — and he's still sitting at 48% ownership. If you need pitching, he's the clearest add on the board this morning. But there are nine more signals worth your time before lineups lock.

Today's Top Adds

Reid Detmers — SP/RP, LAA (48% owned, +17% 7d)

Detmers logged 13.0 innings over the past week with a 2.56 FIP and that absurd 43.8% K rate. This is a five-game sample so it qualifies as early signal territory, but the strikeout jump from 31.3% to 43.8% combined with elite run prevention makes him a priority add in all formats. Ownership surged 17 points this week and it's not stopping — get ahead of it.

Curtis Mead — 1B/2B/3B, WSH (16% owned, +16% 7d)

Mead is mashing with a .432 wOBA and 93.7 mph exit velocity across 20 plate appearances this week, hitting .312 with a homer. His 20.0% walk rate signals elite plate discipline, and the multi-position eligibility adds roster flexibility that's hard to find at 16% ownership. The ownership doubled in a week — this is the last call before he's widely rostered.

Henry Bolte — OF, ATH (11% owned, +6% 7d)

Bolte's 99.0 mph average exit velocity is the highest among today's adds, and he's pairing it with an 83.3% hard-hit rate and a .363 wOBA over the past week. The batting average sits at .333 across five games. At 11% ownership, he's essentially free in most leagues, and the quality of contact suggests the production is sustainable.

Bryce Eldridge — 1B, SF (6% owned, +5% 7d)

The process improvements here are striking: Eldridge cut his strikeout rate from 24.1% to 13.3% while boosting his walk rate from 12.1% to 20.0% over the past seven days. That discipline overhaul fueled a .386 wOBA with 94.7 mph exit velocity. At 6% ownership he's a speculative add, but the underlying approach change — not just results — makes him worth the roster spot now.

Colt Keith — 1B/2B/3B, DET (10% owned, +4% 7d)

Keith went from a .246 wOBA over 30 days to .408 in the last week while slashing his strikeout rate from 21.6% to a minuscule 5.6%. He hit .400 across five games with a 56.7% hard-hit rate and 92.3 mph exit velocity. The multi-position eligibility across first, second, and third makes him a versatile add. The K-rate collapse from over 21% to under 6% is the loudest signal in this data set — something clicked mechanically.

Watch List

Seranthony Domínguez — RP, CWS (54% owned, +14% 7d)

A 0.43 FIP and 40.0% K rate over the past week with a 0.00 ERA and 12.0 K/9. Already 54% owned, so the window may be closing. Monitor for saves opportunity — if he's getting high-leverage work in Chicago, he's a must-roster reliever.

Casey Mize — SP, DET (54% owned, +3% 7d)

Mize posted a 42.9% K rate (up from 24.6% over 30 days), a 0.85 FIP, a 0.00 ERA, and 13.5 K/9 this past week. Still an early signal sample, but the strikeout spike is dramatic. If you're in a league where he's available, he shouldn't be for long.

Vaughn Grissom — 1B/2B/3B, LAA (1% owned)

Grissom's wOBA jumped from .257 to .361 with a 55.6% hard-hit rate and 28 plate appearances — the heaviest workload among Watch List hitters. At 1% ownership, there's no rush, but the playing time signal is the key variable. If he keeps getting everyday at-bats, the bat will play.

Endy Rodríguez — C/1B, PIT (1% owned)

The .111 batting average looks ugly, but a 41.2% walk rate and 100.0% hard-hit rate at 99.7 mph exit velocity tell a different story. Rodríguez is getting on base and crushing the ball when he puts it in play — a classic BABIP regression candidate. Catcher-eligible adds with this contact quality are rare. Watch for the average to catch up.

Ty France — 1B, SD (1% owned)

France slugged two homers this week with a .458 wOBA, a .333 average, and a 66.7% hard-hit rate. At 1% ownership, nobody is paying attention. Worth monitoring for another week to see if this is a real resurgence or a blip.

Stream of the Day

No streaming-specific signals were detected today. With Sunday's full slate already underway, your best bet is to look at Reid Detmers as a multi-start option if he lines up for a turn this week — his 2.56 FIP and 43.8% K rate over 13.0 innings make him more than a streamer at this point. Otherwise, check back tomorrow for Monday and Tuesday matchup-based streaming picks.

Ownership Movers

  • Reid Detmers (48%, +17%): Fully justified. The FIP, K-rate spike, and workload all support continued adds. He's approaching must-roster territory in 12-team leagues.
  • Curtis Mead (16%, +16%): Doubling in ownership in a week is aggressive, but a .432 wOBA with multi-position eligibility at 16% means there's still value. The move is earned.
  • Seranthony Domínguez (54%, +14%): A 0.43 FIP demands attention, but he's a reliever on the White Sox — temper expectations for volume. The underlying stuff is elite; the opportunity may not be.
  • Henry Bolte (11%, +6%): A 99.0 mph exit velocity at 11% ownership is a market inefficiency. This move has room to run.
  • Bryce Eldridge (6%, +5%): The plate discipline transformation is the story. A near-doubling from 6% is warranted given the K-rate and walk-rate swings, though the power hasn't shown up yet (0 HR). If the homers come, he'll be 30%+ in a hurry.

Quick Hits

  • Best contact quality today: Endy Rodríguez owns a 100.0% hard-hit rate at 99.7 mph exit velocity this week. He's hitting .111. That disconnect won't last — in either direction. The walk rate (41.2%) is keeping his wOBA at .357 despite the average.
  • Biggest K-rate spike: Casey Mize jumped from 24.6% to 42.9% strikeout rate week-over-week — a near-doubling that produced a 0.85 FIP. Early signal, but if there's a pitch mix or velocity change driving it, this could stick.
  • Biggest approach change: Colt Keith went from a 21.6% strikeout rate to 5.6% — the single largest K-rate decline among today's signals. Paired with a .400 average, it suggests he's made a genuine mechanical or approach adjustment, not just a hot streak.
  • Bryce Eldridge is the sleeper discipline play: His walk rate nearly doubled from 12.1% to 20.0% while his K rate was nearly halved from 24.1% to 13.3%. That's the kind of dual improvement that scouts dream about from young hitters.
  • Catcher desert relief: If you're streaming catchers, Endy Rodríguez at 1% owned with C/1B eligibility and elite exit velocity is worth a speculative add in two-catcher leagues — the position is too thin to ignore a 99.7 mph EV bat sitting on waivers.
