Seth Lugo is punching out batters at a 33.3% clip over the past week — up from 21.5% over the last 30 days — and at just 30.7% rostered, the window to add him for free is closing fast.

Today's Top Adds

Seth Lugo (P, KC) — Add Now

The K-rate spike is the headline: 33.3% over seven days against a 21.5% 30-day baseline, translating to a gaudy 12.6 K/9. His 1.50 FIP backs up the strikeout surge as legitimate, not luck-driven. Lugo logged 5.0 IP in his last seven days of work and posted a 3.6 ERA — a surface number that actually undersells how sharp he's been underneath. At 30.7% ownership and actually cooling off by 2.4 points over the past week, managers are sleeping on a pitcher whose underlying metrics scream breakout. This is a three-game sample, so we're early, but the FIP-to-ERA gap suggests better results are coming. Add him before the roster percentage catches up to the performance.

Watch List

Bryce Elder (P, ATL) — Watch

Ownership has exploded 24.6 points in a week to 33.2%, and the data supports the frenzy. Elder's K-rate has jumped to 33.3% from 27.7% over 30 days, his FIP sits at a pristine 1.24, and he threw 7.0 IP this past week with a 0.00 ERA and 10.29 K/9. Two-game sample demands patience, but these are elite-level indicators. He's the top watch-to-add candidate if one more start confirms the trend.

Kodai Senga (P, NYM) — Watch

Senga is flashing top-of-rotation stuff with a 34.0% K-rate, 12.31 K/9, and a 1.65 FIP across 11.7 IP in the past week. The 3.08 ERA is solid, and the workload signals a full starter's leash. At 40.9% owned and ticking up, he won't be available everywhere much longer. Two starts is still early — monitor the next outing.

Steven Matz (P, TB) — Watch

The most dramatic K-rate jump on today's board: 36.4% over seven days against a 23.0% 30-day mark. That's a 12.0 K/9 rate paired with a 1.50 ERA and 1.43 FIP. At 2.9% rostered, he's essentially free. The three-game sample is razor-thin, but these are the exact low-ownership, high-upside profiles that win waiver wars.

Kyle Freeland (P, COL) — Watch

Yes, he pitches in Colorado. But a 27.3% K-rate (up from 16.9% over 30 days), a 1.30 FIP, a 1.8 ERA, and 10.8 K/9 across 5.0 IP deserve attention regardless of zip code. Freeland is 1.1% rostered. If the K-rate holds for one more start, he's a viable add in deeper formats.

Brock Burke (P, CIN) — Watch

A 54.5% strikeout rate. Read that again. Burke has nearly doubled his 30-day K-rate (28.6%) in the past week, posting a 0.00 ERA, 14.59 K/9, and a 0.67 FIP across five appearances. The 0.3% ownership tells you nobody is paying attention yet. Reliever eligibility limits his ceiling, but the ratios are absurd.

Gabriel Arias (SS, CLE) — Watch

Arias is the lone position player earning a serious look. His wOBA has surged to .466 over seven days (up from .288 over 30 days), powered by a 103.0 mph average exit velocity and 90.0% hard-hit rate. He's hit two home runs with a .312 average, and his strikeout rate has actually ticked down (33.3% from 34.9%) while walks are up (11.1% from 9.3%). Five games is a respectable sample for a hitter — this isn't noise.

Sam Moll (P, CIN) — Watch

Burke's Cincinnati bullpen-mate is also surging: 37.5% K-rate over seven days (up from 20.0%), a 0.00 ERA, 11.74 K/9, and a 1.80 FIP. At 0.1% rostered, he's a pure speculative add in deep leagues only.

Calvin Faucher (P, MIA) — Watch

A 45.5% K-rate and 15.0 K/9 over the past week with a 0.00 ERA and 1.77 FIP. Faucher's 30-day K-rate was already elite at 38.9%, and it's climbed further. At 0.5% owned, there's zero cost to stash him if you need ratios.

Masataka Yoshida (LF, BOS) — Watch

Yoshida continues to quietly produce: .427 wOBA, .308 average, an 11.1% strikeout rate, and a 27.8% walk rate over the past week. The exit velocity (97.4 mph) and hard-hit rate (72.9%) aren't elite, so the power ceiling is capped, but the plate discipline is extraordinary. At 1.1% rostered, he's an OBP-league goldmine.

Gary Sánchez (C, MIL) — Watch

Two home runs, a .552 wOBA, 101.3 mph exit velocity, and an 83.3% hard-hit rate in five games. Sánchez's strikeout rate has dropped to 27.3% from 33.3% over 30 days while walks have spiked to 27.3%. The catcher pool is shallow enough that a 1.4%-owned backstop mashing this hard warrants attention.

Jeremiah Estrada (P, SD) — Watch

Estrada owns a 38.5% K-rate, 11.25 K/9, 0.00 ERA, and 0.60 FIP over the last week. At 18.6% rostered, he's the most owned reliever on this list but still available in most leagues. The 0.60 FIP across five appearances is borderline ridiculous.

Iván Herrera (C, STL) — Watch

Herrera's wOBA has jumped to .421 from .304, fueled by a 29.6% walk rate and consistent playing time (27 PA in seven days). The exit velocity (92.7 mph) won't wow anyone, but 10.3% owned catchers with everyday at-bats and a .421 wOBA don't stay on waivers long.

Gavin Sheets (LF, SD) — Watch

Sheets is hitting .375 with an 11.8% strikeout rate and .415 wOBA over the past week — a massive improvement from his .301 30-day wOBA. The 91.6 mph exit velocity and 51.7% hard-hit rate temper enthusiasm. Contact-driven hot streaks at this exit velocity profile tend to fade. Monitor, don't chase.

Stream of the Day

No streaming-specific signals triggered today. With a pitching-heavy watch list full of sub-5% owned arms, your best streaming proxy is Steven Matz — a 1.50 ERA, 1.43 FIP, and 12.0 K/9 at 2.9% ownership. He's technically on the watch list, but if you need innings this week, the risk-reward at near-zero roster cost is as good as it gets.

Ownership Movers

  • Bryce Elder (ATL): +24.6% to 33.2% — The biggest mover by a mile, and it's entirely justified. A 1.24 FIP and 10.29 K/9 will do that. The only question is whether two games is enough to trust. The data says yes, the sample says wait one more start.
  • Kodai Senga (NYM): +2.5% to 40.9% — Steady climb reflecting steady production. The 11.7 IP workload over seven days shows he's stretched out and trusted. The ownership curve should steepen if the next start matches.
  • Steven Matz (TB): +0.5% to 2.9% — Criminally under-owned for a pitcher with these peripherals. The 36.4% K-rate should be generating far more adds than a half-point bump.
  • Kyle Freeland (COL): +0.3% to 1.1% — The Coors stigma is keeping ownership suppressed. The 1.30 FIP says don't ignore him.
  • Brock Burke (CIN): +0.2% to 0.3% — A 54.5% K-rate reliever at 0.3% ownership is market inefficiency in its purest form.

Quick Hits

  • Brock Burke's 54.5% seven-day K-rate is the highest on today's board — nearly double his 28.6% 30-day baseline. His 0.67 FIP suggests he's not just getting lucky swings-and-misses.
  • Gabriel Arias is averaging 103.0 mph exit velocity with a 90.0% hard-hit rate. For a 0.6%-owned shortstop, that's the kind of batted-ball data that precedes a sustained power surge.
  • Cincinnati's bullpen is a goldmine: Both Burke and Sam Moll carry 0.00 ERAs this week with combined K-rates above 37%. Deep-league managers should be mining the Reds' pen.
  • Masataka Yoshida's 27.8% walk rate over the past week is elite-tier plate discipline. In OBP or points leagues, he's a borderline must-add at 1.1% owned.
  • Cody Laweryson (MIN) has the weakest profile on today's list — a 5.4 ERA despite a 1.90 FIP and 10.8 K/9. The FIP-ERA gap suggests bad luck or sequencing issues, but the 0% ownership and small sample make him a deep-league-only stash.
