Trevor Larnach: The Signal Keeps Showing Up

Trevor Larnach is posting a .463 wOBA over his last 7 days, and while the sample is tiny — 18 PA across that stretch — this isn't the first time WaiverScout's algorithm has flagged the Twins outfielder. We've had eyes on Larnach since early June, when he was rostered in just 2% of leagues. The signal has kept appearing, and now it's getting louder.

The Rolling Windows Tell a Story

Start with the trajectory. Over 30 days (80 PA), Larnach is hitting .342 with 3 HR and a .409 wOBA. Narrow to 14 days (29 PA), and the line tightens: .370 AVG, 2 HR, .441 wOBA. The most recent 7-day window? A .412 AVG with a .463 wOBA. The trend is unmistakable — performance is accelerating, not regressing.

The strikeout rate deserves attention, though not all of it is encouraging. His 30-day K% sits at a strong 13.8%, but that number has climbed to 17.2% over 14 days and 22.2% over the last 7. That uptick could be noise in a small window, or it could signal pitchers adjusting. Worth watching closely.

On the flip side, his walk rate has moved in the opposite direction — 8.8% over 30 days, down to 6.9% over 14 and 5.6% over 7. The plate discipline profile is getting more aggressive. Whether that's a feature or a bug depends on whether the hard contact keeps showing up.

The Batted Ball Data

And the hard contact is showing up. Larnach's 14-day hard-hit rate is 50% with an average exit velocity of 90.6 mph. Zoom out to 30 days and those numbers get even better: 55.6% hard-hit rate and a 96.4 mph average EV. That 30-day exit velocity is elite-level stuff. The quality of contact is real, even if the recent dip in EV from the 30-day to 14-day window warrants monitoring.

WaiverScout Has Been Tracking This

We first flagged Larnach as a watch on June 18, when he was available in 98% of leagues. He's cycled between watch and deprioritize signals multiple times since — the algorithm reflecting a player whose underlying skills kept flashing but whose consistency hadn't locked in. That pattern is important context: Larnach isn't a sudden breakout. He's a slow build. The skills have been present; the playing time and results are now aligning.

Ownership Window

At just 8% rostered with no movement in the last 7 days, the fantasy industry hasn't caught on yet. Most major outlets — ESPN, RotoWire, FantasyPros — have Larnach on their pages, but he's not generating meaningful pickup buzz. That's your window. If you're hunting for upside at outfield over alternatives like George Springer or deeper-league plays like Chandler Simpson, Larnach's power profile could be emerging as the more interesting bet.

Verdict: Watch

We're at 29 PA of confidence here — early signal territory, full stop. But early signs suggest Larnach could be emerging as a legitimate fantasy contributor. A .409 wOBA over 80 PA is not a fluke. A 55.6% hard-hit rate and 96.4 mph exit velocity over that same stretch are not flukes. The classification stays at Watch because we need to see the strikeout rate stabilize and the playing time hold. But if you have a watchlist spot, Trevor Larnach belongs on it. The signal has been building for weeks. Don't wait for 20% ownership to act.
