Casey Mize is the most actionable arm on waivers right now — a 0.71 ERA and 9.92 K/9 over his last 12.7 innings, backed by a 1.84 FIP that says the results are real, not lucky. If he's available in your league, you're late. But at 55% ownership, there's still a window in nearly half of all formats.

Today's Top Adds

Casey Mize (SP, DET) — 55% Owned (+17% 7d)

Mize's strikeout rate has jumped to 30.4% over the past seven days, up from an already-strong 27.4% over 30 days, and that 1.84 FIP tells you the underlying quality matches the shiny 0.71 ERA. He logged 12.7 innings in the past week — full workload, no pitch-count games. Ownership surged 17 points in a week and it's still climbing. This is a five-start sample so treat it as an early signal, but the convergence of elite FIP, rising K-rate, and increasing usage makes him a priority add in all formats before he crosses that 70% threshold where he's gone everywhere.

Daylen Lile (OF, WSH) — 58% Owned (+7% 7d)

Lile is doing everything right over the past week: .364 AVG, 3 home runs, a monster .540 wOBA — up from .345 over 30 days. The process metrics are what make this compelling, not just the results. His strikeout rate dropped to 11.1% (from 14.0%), his walk rate ballooned to 18.5% (from 7.9%), and he's barreling the ball at 94.3 mph exit velocity with a 64.6% hard-hit rate. That's elite-tier contact quality. With 27 plate appearances in the past week confirming consistent playing time, this is no platoon bat getting favorable matchups. He's the real deal, and at 58% ownership in a surging trend, the window is closing fast.

Xander Bogaerts (SS, SD) — 42% Owned (+4% 7d)

Bogaerts has quietly put together a .368/.447 AVG/wOBA week with a 20.8% walk rate — nearly double his 10.9% 30-day mark — suggesting an upgraded approach at the plate, not just a hot streak. His 94.0 mph exit velocity and 54.2% hard-hit rate show real bat speed behind the numbers. At just 42% owned, he's the best value on this list relative to availability. The name recognition should accelerate adds quickly, so move now if you need a shortstop upgrade.

Watch List

Juan Morillo (RP, AZ) — 9% Owned

A 42.9% strikeout rate over seven days with a -0.14 FIP and a 0.00 ERA — those are video-game numbers. At 9% owned this is speculative, but if Morillo is sliding into high-leverage work in Arizona, that K-rate makes him a potential closer-in-waiting. Monitor his role over the next week.

Amed Rosario (2B/3B, NYY) — 3% Owned

Rosario's 96.1 mph exit velocity is the standout number here, paired with a .382 wOBA, a plummeting strikeout rate (9.5% vs 15.5% over 30 days), and 2 homers in the past week. Multi-position eligibility in New York's lineup makes him interesting if the power sticks.

Carlos Narváez (C, BOS) — 2% Owned

A catcher hitting .417 with a .533 wOBA and a strikeout rate that dropped from 28.6% to 15.4% deserves attention, even in a tiny sample. The 89.2 mph exit velocity is modest, so the batting average is likely inflated. Watch for whether the improved plate discipline (7.7% walk rate, up from 3.6%) sustains before adding.

Bryan Hudson (RP, CWS) — 0% Owned

A 33.3% K-rate, 2.77 FIP, and 0.00 ERA from the White Sox bullpen at 0% ownership. This is the deep-league flier. The 15.0 K/9 over seven days is loud enough to roster in AL-only and deeper mixed formats if you need ratio help.

Brooks Lee (2B/3B/SS, MIN) — 8% Owned

Lee's walk rate spiked to 15.4% from 7.2%, and his 94.1 mph exit velocity shows real bat speed, but the .227 AVG and .275 wOBA this week don't yet justify an add. The approach improvement is the lead indicator — if the hits start falling, he'll move to the "Add Now" tier quickly.

Spencer Steer (1B/OF, CIN) — 12% Owned

Steer's wOBA jumped from .312 to .430 over seven days with a .294 AVG and a homer, and his strikeout rate dipped from 29.1% to 23.8%. The 90.0 mph exit velocity and 41.7% hard-hit rate are below-average though, suggesting the hot week may not sustain at this level. Worth a bench stash in 12-team-plus leagues given his dual eligibility.

Edouard Julien (1B/2B, COL) — 2% Owned

Julien's ownership actually dropped 2 points this week despite a .304 AVG and .357 wOBA. The 51.6% hard-hit rate and 91.7 mph exit velocity are solid, and 26 PA confirm he's playing every day. The Coors factor clouds things, but the underlying contact quality is legitimate enough to keep him on watch in deeper formats.

Stream of the Day

No streaming-specific signals were flagged today — none of the pitching matchups triggered our start-of-the-week criteria. If you need an arm, Casey Mize is the obvious full-roster add over a one-day stream. Check back tomorrow for weekend streaming options as probable pitcher schedules firm up.

Ownership Movers

  • Casey Mize: 55% (+17% 7d) — The biggest mover and it's completely justified. A 1.84 FIP and 30.4% K-rate aren't ownership-inflated noise — they're the kind of underlying numbers that precede a run to 85%+ rostered. The train is leaving the station.
  • Daylen Lile: 58% (+7% 7d) — A 64.6% hard-hit rate and 94.3 mph exit velocity justify every bit of the ownership surge. This isn't hype chasing; the data supports the adds.
  • Xander Bogaerts: 42% (+4% 7d) — The rise is slower because the name suggests "past his prime" to some managers. The 94.0 mph exit velo and .447 wOBA say otherwise. The market is underpricing him.
  • Juan Morillo: 9% (+3% 7d) — A 3-point jump from a tiny base. The 42.9% K-rate will push this higher fast if the role expands. Early movers get the discount.
  • Amed Rosario: 3% (+1% 7d) — Barely registering on the ownership radar, but a 96.1 mph exit velocity from a middle infielder deserves more attention than 3% ownership suggests.

Quick Hits

  • Morillo's -0.14 FIP is the lowest on today's board by a wide margin. Yes, it's a small-sample reliever number, but a negative FIP means he's essentially allowing nothing of value — strikeouts with zero damage on contact. That's a rare combination even in short bursts.
  • Daylen Lile's 18.5% walk rate is the most surprising number in today's data. A young outfielder posting that kind of plate discipline while simultaneously cutting his K-rate to 11.1% signals a possible approach-level leap, not just a lucky week. That's what separates a flash from a breakout.
  • Bogaerts at 42% ownership is market inefficiency. His .447 wOBA and 94.0 mph exit velocity would have him at 80%+ if his name were attached to a 24-year-old prospect. Age bias is leaving free production on your waiver wire.
  • Narváez's strikeout rate cratered from 28.6% to 15.4% in one week. The catcher position is such a wasteland that even an early signal like this — .417 AVG, .533 wOBA — is worth a speculative add in two-catcher leagues. The downside is near zero at 2% owned.
  • Brooks Lee's 94.1 mph exit velocity sits right alongside Bogaerts (94.0) and Lile (94.3) despite producing a .275 wOBA — a clear sign the results are lagging behind the quality of contact. He's a BABIP correction waiting to happen.
