Trent Grisham Is Scorching — and WaiverScout Called It Three Weeks Ago

Trent Grisham is slashing .562 with a .636 wOBA over the last seven days, and if you've been following WaiverScout, this shouldn't surprise you. We flagged Grisham as an Add Now back on May 4th when he was rostered in just 40% of leagues. The signal has only strengthened since then, and the data is clear: this isn't a mirage.

The Numbers Have Shifted — Fast

Let's walk through the rolling windows, because the progression tells the story. Over his last 30 days (102 PA), Grisham posted a .247 AVG with a .332 wOBA — respectable, but not league-winning. Zoom into the 14-day window (40 PA) and it jumps to .314 AVG and a .383 wOBA. Now look at the last seven days: .562 AVG, a .636 wOBA, and a strikeout rate that's cratered to just 5.9% — down from 15.7% over 30 days and 20.0% over 14 days.

That strikeout rate decline is the key. Grisham isn't just getting lucky. He's making more contact, putting more balls in play, and punishing what he swings at. Across his last five games, he's gone 10-for-19 with a homer, collecting multi-hit performances in three of those contests. The 3-for-7 line on May 26th included a home run and two RBI. The 3-for-5 outing on May 22nd was pure contact. This is a hitter locked in.

The Skills Data Backs It Up

This is where skeptics get silenced. Grisham's seven-day exit velocity sits at 97.2 mph with a 50.0% hard-hit rate. That's elite-level contact quality. Even his 30-day hard-hit rate of 42.3% and exit velocity of 91.2 mph suggest a player whose underlying skills were already solid before this hot streak ignited.

The combination of declining strikeouts and rising exit velocity is one of the strongest predictive signals in fantasy baseball. It means a hitter is both identifying pitches better and doing more damage when he connects. With 40 plate appearances over the last 14 days providing a solid sample, this isn't a two-game fluke we're overreacting to.

The Ownership Window Is Still Open — Barely

Grisham sits at 41% rostered, essentially unchanged from where he was when we first flagged him. His ownership velocity has actually been cooling off, meaning the broader fantasy community hasn't caught up to what's happening. That's your window. When a player with these numbers is available in more than half of leagues, you act.

While FantasyPros noted his recent three-hit game and some preseason outlets like Fantasy Baseball Today were already debating his upside back in January, the mainstream fantasy conversation hasn't fully embraced the breakout yet. That's exactly the kind of gap WaiverScout exists to exploit.

In the Yankees outfield alongside Juan Soto, Grisham has a clear everyday role, and he's adding stolen base value too — 2 SB over the last 30 days gives him category flexibility beyond the power and average surge.

Verdict: Add Now

Trent Grisham is an Add Now. A .636 wOBA backed by a 97.2 mph exit velocity and 50.0% hard-hit rate is not noise — it's a hitter whose approach and power have converged. The strikeout rate dropping from 15.7% to 5.9% tells you the plate discipline is real. We identified this signal on May 4th, and every data point since has confirmed it. At 41% rostered, he should be owned in every competitive league. Stop waiting for consensus. The numbers already gave you the answer.
