Vaughn Grissom Is Surging — and Nobody's Paying Attention
Vaughn Grissom just posted a .468 wOBA over the last seven days while cutting his strikeout rate in half. He's rostered in 3% of leagues. That disconnect won't last if this keeps up.
The Signal Is Clear
Look at the rolling windows and the trend jumps off the screen. Over the last 30 days, Grissom carried a .338 wOBA with an 18.2% strikeout rate and a 6.4% walk rate. Decent but unspectacular. Then something clicked. Over the last seven days: a .468 wOBA, an 8.3% strikeout rate, and an 8.3% walk rate across 24 plate appearances. That's not a guy getting lucky on bloopers — he went 2-for-4 with a homer on September 23rd and 3-for-4 with two RBI the day before. He's barreling the ball and putting it in play with authority.
The 14-day numbers (.349 wOBA, .244 AVG, 3 HR) show this isn't a one-game blip. Grissom has been building toward this over the past two weeks, and the last seven days represent the sharpest version of it. The strikeout rate dropping from 18.2% to 8.3% is the most important number here. When a hitter with multi-position eligibility (1B, 2B, 3B) starts making more contact and more hard contact simultaneously, you pay attention.
Skills Check: What the Contact Quality Says
The hard-hit rate tells a nuanced story. At 43.1% over the last seven days, Grissom is hitting the ball significantly harder than his 33.2% 30-day mark and his 28.5% 14-day number. That's a meaningful jump. The exit velocity has ticked up modestly — 87.7 mph over seven days versus 86.3 mph over 30 — which suggests the quality of contact is improving even if he's not elite in raw power metrics. Six homers over the 30-day window at that exit velocity profile tells you he's getting to pitches and elevating, not muscling mistakes.
This is real, but it's the kind of real that needs one more week of confirmation before you burn a priority claim on it.
WaiverScout Has Been Tracking This
We first flagged Grissom as a Watch back on July 12th when he was rostered in just 1% of leagues. We upgraded him to Add Now on July 31st at 6% ownership when the skills flashed. The signal faded and we downgraded him through August, most recently classifying him as Deprioritize on September 16th. But the underlying talent never disappeared — it just went dormant. Now the bat is waking up again, and no other fantasy outlet is talking about it. This signal is ahead of the mainstream.
That history matters. Grissom has shown he can produce in bursts — six homers in 110 plate appearances over 30 days is legitimate pop. The question has always been consistency, and this latest seven-day stretch is the best version of his approach we've tracked: fewer whiffs, more walks, harder contact.
The Ownership Window
At 3% rostered with stable ownership velocity, there is no rush to grab Grissom right now. Nobody else is racing to add him. That's your advantage. You have time to watch one more week and see if the strikeout rate holds below 15% and the hard-hit rate stays elevated. If both conditions persist, the classification likely moves up.
If you're in a deep league or need multi-position flexibility, Grissom is already worth a speculative add over alternatives like Sal Stewart or Royce Lewis depending on their current form and your roster construction.
Verdict: Watch
The data is clear — Grissom's last seven days represent a genuine skills surge, not noise. A .468 wOBA paired with an 8.3% strikeout rate and 43.1% hard-hit rate across 24 plate appearances is a profile worth monitoring closely. The 30-day power (6 HR) provides a floor. Keep him at the top of your watchlist and be ready to move fast if this holds through the next series. At 3% rostered, you have the luxury of patience — but don't sleep through the window.
