Vaughn Grissom Is Heating Up — and the Numbers Back It Up

Vaughn Grissom just posted a .361 wOBA over the last seven days, a massive spike from his .257 mark over the past month. At 1% rostered, almost nobody is paying attention. That's exactly why you should be.

The Signal: A Real Breakout or Another Tease?

Let's be honest about Grissom's track record this season. WaiverScout flagged him as a deprioritize four separate times between mid-April and mid-May. The bat was lifeless — a .188 average and .257 wOBA over 90 plate appearances across the last 30 days told a grim story. We weren't interested, and we told you as much.

But something shifted. We upgraded him to Watch on May 11, then downgraded him again on May 18 when the data didn't hold. Now he's back on the Watch list, and this time the signal is stronger. The last five games tell the story: 7-for-20 with a home run, 11 RBI, and consistent contact. That May 26 explosion — 3-for-5 with a homer and six RBI — wasn't just a fluke game propping up empty numbers. He followed it with three more multi-RBI performances in his next four contests.

Rolling Window Breakdown

The progression across windows is what matters here:

  • 30-day: .188 AVG / .257 wOBA — the ugly baseline everyone sees
  • 14-day: .216 AVG / .279 wOBA — early signs of life
  • 7-day: .292 AVG / .361 wOBA — this is real production

That 7-day wOBA of .361 doesn't just represent improvement — it represents above-average offensive production. The strikeout rate has remained disciplined throughout, sitting at 14.3% over the last week and never exceeding 12.2% over the full 30-day window. He's not selling out for contact at the expense of plate discipline either, maintaining a 7.1% walk rate over the past seven days.

Skills Validation: The Hard Contact Is Legit

Here's what separates this surge from empty BABIP luck: the hard-hit quality is consistent across all three windows. Grissom is posting a 55.6% hard-hit rate over the last seven days, 54.2% over 14 days, and 55.1% over 30 days. The data is clear — he's been hitting the ball hard all month. The results are simply catching up to the quality of contact.

His exit velocity of 88.8 mph over the past week sits within range of his 91.0 mph 30-day average, suggesting he's squaring balls up at a steady clip rather than riding a handful of barreled balls. This is a skill-based foundation, not a mirage.

Opportunity and Ownership Window

Grissom logged 28 plate appearances over the last seven days, confirming consistent playing time in the Angels' lineup. Bettor In Green noted earlier this year that the Angels have been experimenting with Grissom's positional versatility, and his 1B/2B/3B eligibility makes him a flexible roster asset. CBS Sports recently covered his two-RBI performance Friday, but the broader fantasy community hasn't caught on yet.

At 1% rostered with stable ownership velocity, there's no rush to the wire. But that's also the window. If this hard-hit profile continues translating into results for another week, that number moves fast.

Verdict: Watch

Grissom is a Watch, not an add — yet. The hard-hit data has been elite all month, and the results are finally aligning. The 42 plate appearances over five games give us a solid sample to trust the trend, but we need to see this .361 wOBA sustain beyond one hot week given his ugly 30-day baseline. Multi-position eligibility and everyday at-bats make him a compelling stash candidate in deeper leagues. If the surface stats match the underlying quality of contact for one more week, expect an upgrade. Keep him on your shortlist — WaiverScout is watching closely, and if you're in a competitive league, you should be too. Consider him ahead of players like Sal Stewart at the hot corner if the signal strengthens.
