Trent Grisham Is Locked In — And the Data Says This Time It's Real
Trent Grisham is posting a .382 wOBA over the last seven days with a 10.5% strikeout rate, and if you've been ignoring our alerts, you're running out of time to act. WaiverScout first flagged Grisham as an Add Now back on May 4 when he was rostered in just 40% of leagues. We said it again on May 26. And again on June 13. The signal has only strengthened. At 46% rostered, he's still available in more than half of competitive leagues, and the underlying numbers say that window is closing.
The Rolling Window Tells the Story
Over his last 19 plate appearances (7 days), Grisham is slashing .294 with a home run, a .382 wOBA, and — here's the number that matters most — a 10.5% strikeout rate. Compare that to his 30-day mark of 23.1%. That's not a small dip. That's a hitter who has fundamentally tightened his approach at the plate. His walk rate has simultaneously climbed to 10.5% over the last week, up from 7.7% over 30 days. He's swinging at better pitches, making more contact, and taking his walks when pitchers don't give him anything to hit.
The 14-day and 30-day lines are identical — .257 AVG, 2 HR, 1 SB, .341 wOBA across 39 PA — which tells us the recent seven-day surge is genuinely new. This isn't noise from one fluky game. Look at the game log: Grisham went 2-for-4 with a homer and 2 RBI on July 11, followed by 2-for-5 with an RBI on July 9. He's been consistently putting the bat on the ball and doing damage.
The Statcast Data Backs It Up
This is where skeptics need to pay attention. Grisham's hard-hit rate over the last seven days sits at 73.3% with an average exit velocity of 100.0 mph. Those are elite-tier contact quality numbers. Even his 14-day marks are strong — 65.6% hard-hit rate and 99.2 mph exit velocity. He's not getting lucky. He's barreling the baseball with consistency and authority. When a hitter pairs that kind of exit velocity with a sub-11% strikeout rate, you're looking at a recipe for sustained production, not a mirage.
Ownership Context: The Window Is Still Open
At 46% rostered with essentially flat ownership velocity (just +-1% change over the past week), the broader fantasy community hasn't caught on to this surge yet. FantasyPros lists him as a ranked outfielder, and Fantasy Baseball Today posed the "buy Grisham" question months ago. WaiverScout didn't pose the question — we answered it, three times over.
If you're comparing outfield options on the wire, Grisham's combination of contact quality and plate discipline gives him a higher floor than volatile alternatives like Chandler Simpson and a safer profile right now than buy-low candidates like Jordan Walker. Even Randy Arozarena owners should take note — Grisham is producing in a Yankees lineup that provides consistent run-producing opportunities.
Verdict: Add Now
The data is clear. A .382 wOBA. A 73.3% hard-hit rate. A strikeout rate that's been cut in half over the last week. An exit velocity sitting at a round 100 mph. This is a hitter who has refined his approach and is squaring up premium contact. WaiverScout identified this trend at 40% rostered and has tracked every escalation since. At 46%, Grisham is still sitting on your waiver wire in most formats. That's a mistake. Pick him up now — before the ownership spike makes this article a retrospective instead of an opportunity.
