Vaughn Grissom Is Heating Up Again — 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 rostered in just 3% of leagues. The data is clear: this is a real surge, and the mainstream fantasy world hasn't noticed yet.

The Signal: A Week That Demands Attention

Grissom's last seven days have been electric. He's slashing .350 with 2 home runs, a .468 wOBA, and an 8.3% strikeout rate across 24 plate appearances. Compare that to his 30-day line — .242 AVG, .338 wOBA, 18.2% K rate — and you're looking at a player who has meaningfully tightened his approach at the plate. His walk rate has ticked up to 8.3% from 6.4% over the 30-day window, suggesting this isn't just a hot streak built on luck. He's being more selective and doing more damage when he swings.

Look at the recent game log: 2-for-4 with a homer on September 23rd, 3-for-4 with 2 RBI the day before. Over his last five games, Grissom has gone 7-for-19 with 2 homers, 5 RBI, and just 2 strikeouts. That's a hitter locked in.

Skills Check: Real or Mirage?

This is where we pump the brakes slightly. Grissom's hard-hit rate sits at 43.1% over the last seven days — a solid number — but his 14-day mark is just 28.5%, and his 30-day figure is 33.2%. The exit velocity tells a similar story: 87.7 mph over the past week versus 86.3 mph over 30 days. There's improvement, but it's modest on the Statcast side. The contact quality hasn't exploded the way the surface stats have. That gap between the batting line and the underlying quality metrics is what keeps this a Watch rather than an immediate add.

What's encouraging is the plate discipline shift. Cutting your K rate from 18.2% to 8.3% while maintaining an 8.3% walk rate speaks to a genuine adjustment, not just balls finding holes. If that discipline holds for another week and the hard-hit numbers climb with it, this becomes a much louder signal.

WaiverScout Has Been Tracking This

This isn't the first time our algorithm has flagged Grissom. We've been monitoring him since mid-July, when he was rostered in just 1% of leagues. We issued a Watch signal on July 12th, July 20th, and July 28th before upgrading him to Add Now on July 31st at 6% ownership. Since then, he's oscillated between hot and cold stretches — we downgraded him as recently as September 16th when the numbers went flat. Now the signal is rising again, and the pattern is familiar: Grissom runs hot when his approach tightens, and right now his approach is as tight as we've seen it.

The Opportunity

Grissom logged 24 PA in the last seven days, confirming consistent playing time for the Angels. His multi-position eligibility (1B, 2B, 3B) adds roster flexibility that's valuable down the stretch. At 3% rostered with no movement in ownership velocity, this is a player hiding in plain sight. No major fantasy outlets are talking about him right now — this signal is ahead of the curve.

The Verdict: Watch

Grissom is a Watch, not an add — yet. The surface production over the last week is outstanding, but the hard-hit data at 43.1% and 87.7 mph exit velocity needs another week to confirm the breakout is backed by real quality contact improvement. If you're in deeper leagues or need positional flexibility, he's worth a speculative grab now. In standard formats, keep him on your radar and check back. The plate discipline numbers are real. If the Statcast catches up, this escalates fast.

For similar multi-position options, keep an eye on Sal Stewart and Royce Lewis, though Grissom's current trajectory and playing time make him the most interesting of the group right now.
