Vaughn Grissom Is Hitting .348 Over the Last Week — and WaiverScout Has Been Watching Since May
Vaughn Grissom is posting a .408 wOBA over the last seven days, and his ownership just spiked from 1% to 6% in a week. If you've been following WaiverScout's alerts, none of this is a surprise. We first flagged Grissom as a watch back on May 11 when he was rostered in just 1% of leagues. We kept him on the radar through June and into July, even as his profile bounced between watch and deprioritize. On July 28, we elevated him to watch again at 2% ownership. Now, the signal has strengthened enough to upgrade him to Add Now. The data is clear.
The Rolling Window Tells the Story
Grissom's numbers have been building momentum across every timeframe. Over the last 7 days: a .348 AVG, 1 HR, and a .408 wOBA across 26 plate appearances. Zoom out to 14 days and you see .312 with 2 HR and a .365 wOBA over 51 PA. The 30-day line is a .333 AVG, 3 HR, and a .374 wOBA across 81 PA. This isn't a two-game blip — it's a sustained rise with the most recent window being the strongest.
His plate discipline is trending in the right direction too. His strikeout rate has ticked down from 23.5% over 30 days to 23.1% over the last week — a modest but meaningful drop. More importantly, his walk rate has jumped from 4.9% over 30 days to 7.7% in the last seven. That's the kind of approach improvement that suggests a hitter finding his timing and making better swing decisions at the plate.
The Quality of Contact Is Improving
This is where the case gets even more compelling. Grissom's exit velocity has climbed from 85.3 mph over 30 days to 92 mph over the last 14 days — a massive jump that indicates real mechanical improvement, not just luck. His hard-hit rate tells the same story, rising from 27.8% at the 30-day mark to 33.3% over the last two weeks. He's squaring balls up with more authority, and the results are following.
That 3-for-5 game against the Astros on July 27, which included a homer and two RBI, wasn't an outlier — it was the peak of a trend that's been building for weeks. FantasyPros noted that performance, and the broader fantasy community is starting to take notice.
Positional Versatility and Playing Time
Grissom carries 1B, 2B, and 3B eligibility, which is roster construction gold on the waiver wire. The Angels have been experimenting with his versatility all season, and he's been rewarded with consistent playing time — 26 PA in the last 7 days and 81 over 30 days confirms he's in the lineup regularly. That playing time floor makes his production profile actionable, not speculative.
If you're weighing Grissom against other multi-position options on the wire, consider how he stacks up against names like Sal Stewart or Royce Lewis at the hot corner. Grissom's .408 wOBA over the last week is hard to ignore regardless of the competition.
The Window Is Closing
At 6% rostered with a +5% surge in the last week, ownership is accelerating. This is the inflection point — where a player goes from hidden gem to consensus add within days. WaiverScout identified this signal when Grissom was at 1%. The numbers have only gotten stronger since.
Verdict: Add Now
Grissom is a clear add in all formats. A .408 wOBA backed by rising exit velocity, improving plate discipline, multi-position eligibility, and consistent playing time — this is the profile you want off the wire. The data supports the breakout. The ownership velocity confirms you're running out of time to act. Pick him up before the rest of your league catches up.
