Nolan Arenado is hitting .286 with a .422 wOBA over the last seven days while walking at a 19.2% clip — and he's sitting at just 25% ownership. If you need a corner infielder for the stretch run, this is the move. Here's everything our signals flagged in the last 24 hours.

Today's Top Adds

Nolan Arenado (3B, AZ) — 25% Owned

Arenado's seven-day wOBA of .422 represents a massive jump from his .281 mark over the past 30 days, and the underlying process supports the surge. His strikeout rate has dropped from 18.9% to 15.4% while his walk rate has more than doubled — from 8.4% to 19.2%. That's a hitter who has recalibrated his approach at the plate. Two home runs across 26 plate appearances in a solid five-game sample give this real substance. At 25% ownership with no meaningful movement in either direction, you have a clean window to add before the weekend slate generates attention. He's the top priority this morning.

Watch List

Coby Mayo (1B/3B, BAL) — 19% Owned

Three home runs in the last week with a .485 wOBA, and the plate discipline indicators are trending hard in the right direction: strikeout rate down from 26.4% to 19.0%, walk rate up from 8.0% to 14.3%. He's knocking on the door of an Add Now tag. If he keeps this K-rate suppression going through the weekend, he's a priority claim by Monday.

Cam Smith (OF, HOU) — 11% Owned

Smith posted a .579 wOBA over the last seven days — the highest on today's board — with a .389 average, three home runs, and a 58.3% hard-hit rate across 20 plate appearances. His walk rate jumped from 5.1% to 10.0%. The raw power output is eye-catching, but at 11% ownership and with no ownership trend data showing acceleration, this is still a monitor. Houston's lineup gives him opportunity; the question is sustainability.

Jared Triolo (1B/2B/3B/SS, PIT) — 1% Owned

A .555 wOBA with a .600 batting average and a 0.0% strikeout rate in the last week is the kind of stat line that screams small sample. And it is — but the multi-position eligibility and the leap from a .310 30-day wOBA make Triolo worth monitoring in deeper leagues. His 89.8 mph exit velocity and 50.0% hard-hit rate suggest the contact quality is real even if the average will regress.

Victor Mesa Jr. (OF, TB) — 3% Owned

Mesa has been quietly mashing: .409 average, two homers, .487 wOBA, and a 91.1 mph exit velocity over the last seven days across 23 plate appearances. The 53.1% hard-hit rate supports the production. At 3% ownership, he's essentially free. Worth a speculative add in leagues with deep benches.

Nathaniel Lowe (1B, CLE) — 3% Owned

Lowe's .446 wOBA and 92.2 mph exit velocity over the past week are backed by two home runs and a 41.7% hard-hit rate. The average sits at just .250, but the walk rate has nearly doubled from 8.2% to 15.0%, suggesting improved selectivity. With 20 plate appearances confirming consistent playing time, he's generating real value at a 3% ownership threshold.

Luis Campusano (C, SD) — 1% Owned

Catcher-needy managers, take note. Campusano has a .438 wOBA over the past week with a .333 average and two home runs. His strikeout rate plummeted from 22.7% to 12.5%, and he's logged 24 plate appearances in five games — clear everyday usage. At 1% ownership, he's the cheapest catcher producing at this level.

Joe Mack (C, MIA) — 2% Owned

Mack's 94.4 mph exit velocity is the hardest contact on today's entire report. His wOBA is up from .294 to .346 with a 50.0% hard-hit rate and a declining strikeout rate (26.2% to 23.5%). One homer and a .294 average won't blow the doors off, but the exit velocity data is a leading indicator worth watching at the catcher position.

Hagen Smith (SP/RP, CWS) — 13% Owned

Smith's 41.7% strikeout rate over the last seven days is elite by any standard, and his 0.24 FIP screams that the results are backed by dominant stuff. He logged 7.0 innings in the last week, indicating rotation-level workload. The question is opportunity and role clarity on a rebuilding White Sox roster. If he locks into starts, he's a must-add.

Brent Headrick (RP, NYY) — 18% Owned

A 40.0% strikeout rate, a 1.25 FIP, and a 0.00 ERA over the last seven days from a reliever on the Yankees. Headrick's K-rate rose from 33.3% to 40.0%, and he's generating swings and misses at an accelerating clip. His 13.33 K/9 is filthy. The reliever tag limits upside in some formats, but in leagues that reward holds or ratios, he's a high-value add.

Stream of the Day

No streaming-specific signals were detected today. With the pitching watch list featuring Hagen Smith and his 0.24 FIP, he's the closest thing to a streaming option if you're willing to bet on a short track record. Check back tomorrow for targeted two-start pitcher recommendations heading into the new week.

Ownership Movers

Ownership movement was remarkably flat across the board over the past seven days, which is why the window is open on several of these players. Brent Headrick ticked up 1% to 18% — justified by a 40.0% K-rate and 1.25 FIP, but the market hasn't caught up to the dominance. Hagen Smith sits at 13% with no recorded ownership change despite a 41.7% K-rate and a 0.24 FIP — this is a market inefficiency in leagues that track strikeouts. Nathaniel Lowe at 3% with zero movement and a .446 wOBA is nearly invisible to most leagues. Cam Smith at 11% hasn't budged despite a .579 wOBA week. The lack of ownership momentum on these names means you have time — but probably only through the weekend before the Sunday night transaction rush.

Quick Hits

  • Jared Triolo's 0.0% strikeout rate over the past week (down from 12.0% over 30 days) is the most extreme K-rate suppression on today's board. Unsustainable, but the contact ability is real — a .600 average doesn't happen by accident even in small samples.
  • Joe Mack's 94.4 mph exit velocity leads all hitters in today's report, outpacing Nathaniel Lowe's 92.2 mph and Victor Mesa Jr.'s 91.1 mph. The catcher position premium makes this particularly notable.
  • Nolan Arenado's walk rate surge — from 8.4% to 19.2% in seven days — is the largest walk rate jump on the board. When a veteran hitter suddenly starts taking more walks while also hitting for power, that's usually a sign of improved pitch recognition, not luck.
  • Two catchers appear on the Watch List today — Luis Campusano (.438 wOBA) and Joe Mack (.346 wOBA) — both at 1-2% ownership. If you've been streaming catchers all season, these are stabilizing options.
  • Hagen Smith's 0.24 FIP is the lowest on today's report, edging out Brent Headrick's 1.25. Both are generating elite strikeout numbers with K-rates above 40%. The pitching wire hasn't been this interesting in weeks.
