Vaughn Grissom Is Heating Up — And Nobody's Paying Attention

Vaughn Grissom just posted a .468 wOBA over the last seven days while cutting his strikeout rate in half, and he's sitting on the waiver wire in 97% of leagues. The data is clear: something has clicked for the Angels' multi-position eligible bat, and the fantasy world hasn't noticed yet.

The Rolling Numbers Tell the Story

Look at Grissom's trajectory across the rolling windows and the improvement is unmistakable:

  • 7-day: .350 AVG, 2 HR, .468 wOBA, 8.3% K%, 8.3% BB% across 24 PA
  • 14-day: .244 AVG, 3 HR, .349 wOBA, 18% K%, 8% BB% across 50 PA
  • 30-day: .242 AVG, 6 HR, .338 wOBA, 18.2% K%, 6.4% BB% across 110 PA

That strikeout rate plummeting from 18.2% over 30 days to 8.3% over the last week is the headline. Grissom went from a free-swinging liability to someone making consistent, quality contact. His last five games back it up: he's struck out just twice while going 7-for-19 with two homers and five RBI. The plate discipline is real — his walk rate has climbed alongside the drop in punchouts, suggesting a genuine approach adjustment, not just batted-ball luck.

Skills Check: What the Underlying Data Says

Here's where you need to temper some enthusiasm. Grissom's hard-hit rate spiked to 43.1% over the last seven days, a solid number, but his 14-day mark sits at 28.5% and his 30-day at 33.2%. The exit velocity tells a similar story — 87.7 mph over seven days versus 86.3 mph over 30 days. That's a modest uptick, not a dramatic shift. The power is showing up in the results (6 HR over 30 days is legitimate), but the batted-ball quality needs to sustain this recent surge for the breakout to hold.

The 30-day .338 wOBA is a perfectly respectable baseline, and the 6 homers across 110 PA show the pop is there. What makes this week interesting is the combination of improved contact quality and improved plate discipline happening simultaneously.

WaiverScout Has Been Tracking This

This isn't the first time our algorithm has flagged Grissom. WaiverScout first identified him as a Watch back on July 12 at just 1% ownership. We upgraded him to an Add Now on July 31 when the signals aligned, then cycled him through Deprioritize windows during cold stretches. The pattern is telling — Grissom keeps generating signals because the underlying talent keeps flashing. He was classified as Deprioritize just a week ago on September 16, and now he's surged right back onto the radar. The volatility is the story, but so is the upside ceiling.

The Opportunity Window

At 3% rostered with stable ownership velocity, no one is rushing to grab Grissom. No mainstream fantasy outlets are talking about him right now — this signal is ahead of the curve. His multi-position eligibility (1B, 2B, 3B) adds roster flexibility that raw stats alone don't capture, especially in deeper formats where a hot bat you can slot into multiple positions is gold.

With 24 PA over the last seven days, he's getting consistent run with the Angels — this isn't a pinch-hit cameo. He's in the lineup and producing. If you're looking at similar profiles at the hot corner, names like Sal Stewart and Royce Lewis offer comparable positional value, but neither is matching Grissom's last-week surge.

Verdict: Watch

Grissom belongs on your watchlist, not your roster — yet. The 7-day numbers are electric, but the underlying batted-ball data hasn't fully caught up to the stat line. The hard-hit rate and exit velocity improvements are real but modest. If the strikeout rate stays suppressed and the hard contact sustains through another week of games, this becomes an add. For now, monitor daily and be ready to move fast. At 3% ownership, you have time — but not much.
