Vaughn Grissom Is Hitting — And WaiverScout Saw It Coming

Vaughn Grissom is slashing at a .408 wOBA over the last seven days, his walk rate is climbing, and he's rostered in just 6% of leagues. If you've been following WaiverScout's signals, none of this is a surprise. We've had eyes on Grissom since late May, flagging him as a watch candidate repeatedly through June and July while he sat at 1-2% ownership. The signal kept building. Now it's screaming. This is an Add Now.

The Rolling Window Tells the Story

Start with the trend lines, because they're all moving in the right direction. Over the last 30 days, Grissom has posted a .333 AVG and .374 wOBA across 81 plate appearances — strong production over a legitimate sample. Zoom into the last seven days and the numbers get better: a .348 AVG, .408 wOBA, and a walk rate that's jumped from 4.9% (30-day) to 7.7%. His strikeout rate has actually ticked down slightly, from 23.5% to 23.1%. He's not selling out for contact — he's being more selective and doing more damage.

The power is showing up too. Grissom has 3 home runs over the last 30 days, including 1 in his last seven. On July 27th, he went 3-for-5 with a homer and 2 RBI. Two days ago he drove in 2 more runs. The production is consistent, not spiked by one freak game.

Statcast Backing: Exit Velocity Is Surging

Here's what makes this sustainable rather than fluky. Grissom's average exit velocity over the last 14 days sits at 92 mph with a 33.3% hard-hit rate. Compare that to his 30-day numbers: 85.3 mph EV and 27.8% hard-hit rate. That's a massive jump in quality of contact over the more recent window. He's not getting lucky — he's squaring the ball up harder and more frequently. The batted-ball data validates the surface stats.

Opportunity Is Locked In

Grissom logged 26 plate appearances over the last seven days, confirming consistent playing time in the Angels' lineup. Earlier this season, the Angels experimented with Grissom in left field alongside Oswald Peraza, suggesting the organization values his bat enough to find ways to keep it in the lineup. At 2B, he offers a position where the waiver wire often runs dry, making his current 6% roster rate all the more absurd.

The Ownership Window Is Closing

Grissom's ownership has jumped +5% in the last week alone, and the velocity is rising fast. At 6%, he's still widely available, but that won't last. For context, if you need middle-infield help, the alternatives most managers are considering — players like Brice Turang, Nico Hoerner, or Bryson Stott — are far more widely rostered without producing Grissom's recent numbers. A .408 wOBA at this roster rate is a market inefficiency, plain and simple.

WaiverScout first flagged Grissom as a watch candidate on May 11th when he was rostered at 1%. We watched through the noise — periods where the algorithm deprioritized him when the skills weren't supporting the signal. But starting in late July, every indicator aligned: performance, plate discipline, quality of contact, and playing time. On July 28th, we moved him from watch to the cusp of an add. Now, with 81 PA of data confirming the trend, the data is clear.

Verdict: Add Now

Vaughn Grissom is a priority add in all formats. The 30-day wOBA is .374. The 7-day wOBA is .408. Exit velocity has jumped nearly 7 mph between his 30-day and 14-day windows. The strikeout rate is stable, the walk rate is improving, and he's playing every day. At 6% rostered, this is one of the clearest adds on the wire right now. The numbers back it up — go get him before your league catches on.
