Trent Grisham Is Surging — And WaiverScout Called It Three Times Already

Trent Grisham is slashing strikeouts, barreling everything, and posting a .382 wOBA over the last seven days. If you've been ignoring the signal, the data is making it harder to look away.

WaiverScout first flagged Grisham as an Add Now back on May 4th, when his roster percentage sat at just 40%. We flagged him again on May 26th at 41%, and again on June 13th at 50%. Each time, the underlying skills said this player deserved a roster spot. Now, sitting at 46% rostered, he's still available in more than half of leagues — and the signal has only strengthened.

The Numbers Have Shifted — Fast

Look at the 7-day vs. 30-day split and the story writes itself:

  • wOBA: .382 over the last 7 days, up from .341 over 30 days
  • K%: Dropped from 23.1% (30-day) to just 10.5% over the last week
  • BB%: Climbed from 7.7% to 10.5% in the same window
  • AVG: .294 over the last 7 days vs. .257 over 30

A hitter who cuts his strikeout rate in half while increasing his walk rate is making a real mechanical adjustment. This isn't noise. Over 39 plate appearances in his last 5 games, Grisham has demonstrated improved plate discipline alongside legitimate power — 1 HR, 1 SB, and a batting line that demands attention.

The Statcast Data Validates Everything

This is where Grisham's surge moves from interesting to actionable. His hard-hit rate over the last seven days sits at 73.3%, with an average exit velocity of 100.0 mph. Even his 14-day numbers are strong: 65.6% hard-hit rate and 99.2 mph exit velocity. These aren't fluky bloop singles propping up a batting average. Grisham is driving the ball with authority, and the quality of contact supports the surface-level production.

A .382 wOBA backed by elite exit velocity and a 73.3% hard-hit clip is real. The data is clear — this isn't a three-game mirage built on BABIP luck. The contact quality underneath gives this surge a foundation.

Ownership Window Is Still Open

At 46% rostered with only a +1% change over the last week, the broader fantasy community hasn't caught up yet. The ownership velocity is stable, meaning you still have time — but not much. ESPN has Grisham hitting .236 on the season, which is exactly why managers are sleeping on him. Season-long averages are hiding the recent breakout in plate discipline and contact quality.

For managers weighing outfield options, Grisham's combination of power, patience, and hard contact makes him a more compelling add right now than fringe options like Jordan Walker, who carries higher name recognition but may not match Grisham's current production floor. If you're in a league where Randy Arozarena is unavailable, Grisham fills a similar profile — a switch-capable outfielder with pop and improving discipline.

Verdict: Add Now

Grisham is an Add Now. A .382 wOBA, 100.0 mph exit velocity, 73.3% hard-hit rate, and a strikeout rate that's been cut from 23.1% to 10.5% — this is the profile of a hitter figuring it out. WaiverScout identified this signal in early May. The skills have persisted and now the results are catching up. He's still sitting on waivers in more than half of fantasy leagues. That won't last. Pick up Trent Grisham before the ownership spike makes this conversation moot.
