Reid Detmers is striking out 43.8% of batters faced over the last seven days — up from 31.3% over the prior month — and if you haven't already moved on him, you're behind 17% of your league who grabbed him this week. He's the headliner of a Monday waiver wire loaded with surging bat signals and a couple of arms flashing elite stuff in small windows.

Today's Top Adds

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

Detmers logged 13.0 innings over the past seven days with a 2.56 FIP and that absurd 43.8% strikeout rate. This is a pitcher whose 30-day K rate sat at 31.3% — already solid — and has now vaulted into elite territory. The five-game sample demands caution, but the ownership surge tells you the smart money is already moving. At 48% rostered, he's still available in the majority of leagues. That won't last through the week.

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

Mead is mashing. A .432 wOBA over the last seven days, backed by 93.7 mph exit velocity and a 20.0% walk rate that shows elite plate discipline. He slashed .312 with a homer in his last five games across 20 plate appearances — consistent playing time that makes him an immediate lineup option. The multi-position eligibility is a bonus. At 16% ownership and surging, the window to buy low is closing fast.

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

Bolte's batted-ball data is screaming. An 83.3% hard-hit rate with 99.0 mph average exit velocity over the past week is the kind of quality contact that sustains production. His .363 wOBA is up from .325 over 30 days, and the .333 batting average over five games shows hits are falling. At 11% rostered, he's a near-free add in most formats. The power hasn't shown up yet — zero homers this week — but with that exit velocity, it's a matter of when, not if.

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

This is the profile change you chase. Eldridge's strikeout rate dropped from 24.1% over 30 days to 13.3% in the last seven, while his walk rate jumped from 12.1% to 20.0%. That's a completely different hitter. His wOBA surged from .279 to .386, exit velocity is sitting at 94.7 mph, and at 6% ownership he's essentially unowned. The .273 average won't jump off the page, but the underlying process — fewer whiffs, more walks, hard contact — is textbook breakout material.

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

Keith has been the best hitter no one is rostering. A .408 wOBA on a .400 batting average this week, with a 5.6% strikeout rate that's down from 21.6% over 30 days. He's walking at 11.1% and making hard contact at a 56.7% clip with 92.3 mph exit velocity. The multi-position eligibility across first, second, and third base gives him plug-and-play utility. At 10% ownership, he's the kind of add that looks obvious in two weeks.

Watch List

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

A 0.00 ERA with 12 K/9 and a 0.43 FIP over the last week. The 40.0% K rate is up from 28.6% over 30 days. He's already 54% rostered, so this is more confirmation than opportunity in shallow leagues — but in deeper formats, the ratios are elite. Still an early signal at five games. Watch for sustained workload.

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

Mize posted a 0.00 ERA, 13.5 K/9, and a 0.85 FIP this past week. His K rate spiked to 42.9% from 24.6% over 30 days. That's a massive jump and warrants attention, but five games is a thin reed. If you're in a league where he's available, monitor one more start before committing.

Vaughn Grissom (1B/2B/3B, LAA) — 1% rostered (+1% 7d)

Grissom's wOBA jumped from .257 to .361 over the past week with a homer and 28 plate appearances — he's getting consistent run. At 1% rostered, this is deep-league territory only, but the playing time is there and the underlying trend is positive.

Endy Rodríguez (C/1B, PIT) — 1% rostered (+1% 7d)

The .111 batting average looks ugly, but dig deeper: a 41.2% walk rate, 100.0% hard-hit rate, and 99.7 mph exit velocity. Rodríguez is seeing the ball well and hitting it hard — the results just haven't caught up. At catcher, where production is scarce, that batted-ball profile is worth monitoring closely.

Ty France (1B, SD) — 1% rostered

France launched 2 homers this week with a .458 wOBA, .333 average, and 92.0 mph exit velocity. His wOBA jumped from .335 to .458 in seven days. At 1% rostered, he's a speculative grab in deeper leagues if the power surge holds through another week.

Stream of the Day

No streaming-specific signals triggered today. With both Detmers and Mize flashing elite K rates, they're worth consideration as streaming arms if you don't plan to hold — but their recent performance argues for a longer leash than a one-start rental. Check back tomorrow for matchup-driven streaming picks.

Ownership Movers

  • Reid Detmers (+17% to 48%): Entirely justified. The strikeout spike, low FIP, and heavy workload all support the move. He's the most actionable arm in today's report.
  • Curtis Mead (+16% to 16%): He essentially went from unowned to owned in a week. The .432 wOBA and consistent plate appearances back the surge. This train is still boarding.
  • Seranthony Domínguez (+14% to 54%): Strong ratios justify the add, though the early sample size means some of this is speculative. The 0.43 FIP is real.
  • Henry Bolte (+6% to 11%): Deserves to be rostered in far more leagues given the exit velocity and hard-hit data. The ownership hasn't caught up to the quality of contact yet.
  • Bryce Eldridge (+5% to 6%): The process improvement — K rate down, walk rate up — is the kind of signal that precedes sustained production. Still widely available and worth the speculative add.

Quick Hits

  • Endy Rodríguez posted a 100.0% hard-hit rate with 99.7 mph exit velocity this week despite hitting just .111. That's the most extreme batted-ball-to-average disconnect in today's data — and at catcher, it's worth a stash.
  • Colt Keith's strikeout rate dropped from 21.6% to 5.6% in one week. That's a 16-point swing. Whether it holds or not, you rarely see approach changes that dramatic without something mechanical clicking.
  • Bryce Eldridge and Curtis Mead both posted 20.0% walk rates over the past seven days. Patient hitters tend to be sustainable hitters — and both are under 20% rostered.
  • Casey Mize and Reid Detmers both crossed 42% K rates this week. For context, Detmers sat at 31.3% over 30 days and Mize at 24.6%. Both nearly doubled their baseline — track whether the swing-and-miss sticks.
  • Henry Bolte's 99.0 mph exit velocity is the highest among today's position player adds. Combined with 83.3% hard-hit quality, he's squaring the ball up better than anyone else on this list.
