Tristan Peters is the top pickup in fantasy baseball this morning — the White Sox outfielder posted a .586 wOBA over the past seven days with a 92.4 mph average exit velocity, and at 40% ownership he's still available in more than half of leagues despite a staggering +37% ownership surge in the last week. If he's on your wire, he won't be for long.

Today's Top Adds

Tristan Peters (OF, CWS) — 40% Owned

Peters is doing everything right over the last five games: .429 AVG, 3 HR, a .586 wOBA that's jumped from an already-strong .448 over 30 days. His strikeout rate has dropped to 12.5% from 16.7% while his walk rate ticked up to 12.5%. The hard-hit rate of 52.1% and 92.4 mph exit velocity confirm this isn't hollow batting average — he's squaring the ball up with authority. A 128 wRC+ and 24 plate appearances in seven days mean he's locked into the lineup. Ownership has exploded from 3% to 40% in a week. This is the last call before he's universally rostered.

Lawrence Butler (OF, ATH) — 60% Owned

Butler's wOBA has surged from .386 to .508 over the past week, fueled by elite plate discipline — a 25.9% walk rate that nearly doubled his 13.3% 30-day mark. He's hitting .400 with a homer, posting a 54.1% hard-hit rate and 91.9 mph exit velocity across 27 plate appearances. At 60% ownership he's already widely rostered, but if you're in a league where he slipped through the cracks, this is a priority add. The walk rate spike suggests a hitter seeing the ball exceptionally well, not just getting lucky on contact.

Coby Mayo (1B/3B, BAL) — 10% Owned

Mayo remains widely available at just 10% ownership despite a .406 wOBA, .300 AVG, and 2 HR over the past seven days. His 50.0% hard-hit rate is solid, and his 22 plate appearances confirm he's getting consistent run in Baltimore's lineup. The 30-day wOBA of .366 shows this isn't a one-week mirage — he's been productive over a longer window too. Corner infield eligibility adds roster flexibility. At 10% owned, he's the highest-upside add on this list relative to his availability.

Watch List

Paul Blackburn (SP/RP, NYY) — 9% Owned

Blackburn's strikeout rate has climbed to 26.7% from 22.4% over 30 days, and his 1.75 FIP over the last week is elite. The Yankees affiliation gives him a long leash. Monitor for one more start before committing a roster spot, but if the K-rate holds, he becomes a must-add.

Adrian Morejon (RP, SD) — 23% Owned

A 31.6% strikeout rate and 1.90 FIP over 5.0 innings in the last seven days — Morejon posted a 0.00 ERA and 10.8 K/9. He's in a relief role, which limits his ceiling, but the ratios are elite. Worth monitoring for saves or holds eligibility.

Lars Nootbaar (OF, AZ) — 2% Owned

Nootbaar is the sneakiest name on this list. His wOBA jumped from .327 to .481 in a week, and the quality metrics scream legitimacy: 66.7% hard-hit rate, 99.3 mph exit velocity. He's hitting .333 with 2 HR across 20 PA. At 2% owned, nobody is watching — which means you have time. One more strong week and he's a priority add.

Jonah Heim (C, ATH) — 3% Owned

Heim's wOBA has nearly doubled from .208 to .365 in a week. A 58.3% hard-hit rate and 92.8 mph exit velocity support the .312 AVG and 1 HR. Catcher is a wasteland — if you're streaming the position, Heim deserves a look. His strikeout rate dipped to 17.6% from 18.4%, a modest but directionally correct move.

J.T. Realmuto (C, PHI) — 19% Owned

Realmuto's strikeout rate cratered to 10.5% from 18.2%, and his walk rate climbed to 10.5% from 9.1%. The .376 wOBA (up from .275) is backed by 2 HR and a 50.0% hard-hit rate. At 19% owned, the name recognition hasn't translated to roster percentage — likely injury-related attrition earlier in the season. He's worth a speculative add in two-catcher leagues right now.

Joc Pederson (1B, TEX) — 5% Owned

Pederson's hard-hit rate of 70.8% and 95.1 mph exit velocity are the best contact quality numbers on this entire report. His .370 wOBA includes 2 HR on a .200 AVG — classic Joc: low average, high damage. Ownership is actually cooling (-2% in 7d), which creates a buy-low window if the batted-ball data sustains.

Clayton Beeter (RP, WSH) — 14% Owned

Beeter's K-rate spiked to 27.8% from 21.6%, and his 2.25 FIP supports the 1.91 ERA and 9.57 K/9 over the last week. Ownership dipped 2%, which is counterintuitive given the performance. Worth a watch in leagues that reward holds or where closer volatility could push him into save opportunities.

Stream of the Day

No streaming-specific signals triggered today. The algorithm didn't flag any spot starters or matchup-driven one-week plays worth chasing. If you need pitching help, Paul Blackburn is the closest thing — his 1.75 FIP and 26.7% K-rate make him a viable streaming arm if he's lined up for a start this week, though he carries SP/RP eligibility, so confirm his role before plugging him in. Otherwise, check back tomorrow.

Ownership Movers

  • Tristan Peters (CWS): 40% (+37% in 7d) — Completely justified. A .586 wOBA, 52.1% hard-hit rate, and declining strikeouts across a five-game sample make this the most legitimate ownership spike of the week. The train is leaving the station.
  • Lawrence Butler (ATH): 60% (+11% in 7d) — Also justified. A 25.9% walk rate and .508 wOBA show a hitter in complete control of the strike zone. He should be closer to 80%.
  • Coby Mayo (BAL): 10% (+7% in 7d) — The move is right, but the pace is too slow. A .406 wOBA from a 10%-owned player with dual positional eligibility in Baltimore's lineup? This ownership should be triple what it is.
  • Paul Blackburn (NYY): 9% (+4% in 7d) — Early movers are on to something. The 1.75 FIP is hard to ignore, though the small sample warrants caution. Justified as a speculative add.
  • Adrian Morejon (SD): 23% (+1% in 7d) — Flat ownership despite a 31.6% K-rate and sub-2.00 FIP. The reliever discount is real, but in leagues that count holds or K/9, he's an asset.

Quick Hits

  • Lars Nootbaar's 99.3 mph average exit velocity over the past week is the highest on this entire report — and he's rostered in just 2% of leagues. That's a market inefficiency.
  • Joc Pederson's 70.8% hard-hit rate is elite by any standard, yet his ownership dropped 2% this week. The .200 AVG is scaring off managers, but the power metrics say the homers are coming in bunches.
  • Jonah Heim went from a .208 wOBA to .365 in seven days — the largest wOBA jump among catchers on today's report. At 3% owned, he's essentially free.
  • J.T. Realmuto's strikeout rate dropped from 18.2% to 10.5% in a week. That's a dramatic shift in approach that, if it holds, makes him a top-10 catcher again.
  • Lawrence Butler's 25.9% walk rate over the past seven days is more than double his 30-day rate of 13.3%. That kind of patience spike usually precedes a sustained hot streak — pitchers are either afraid of him or he's laying off everything outside the zone. Either way, it's bullish.
