Zack Gelof Is Surging — and WaiverScout Called It First

Zack Gelof is slashing with authority again, posting a .407 wOBA over the last seven days with three home runs, two stolen bases, and a strikeout rate that's been cut nearly in half. At 17% rostered, the window to grab him is closing fast — but it's still open. This is an Add Now.

We've Been on This Since April

WaiverScout first flagged Gelof as a watch back on April 29, when his ownership was sitting at 0%. We escalated him to Add Now on May 8 at just 5% rostered. Since then, ownership has more than tripled to 17% with a +5% jump in the last week alone. The signal has only strengthened at every checkpoint. If you acted on our earlier alerts, you're already reaping the rewards. If you didn't, this is your last comfortable entry point before he becomes a consensus add.

The Rolling Numbers Tell the Story

Look at the trajectory across Gelof's rolling windows:

  • 7-day: .296 AVG, .407 wOBA, 13.8% K%, 3 HR, 2 SB in 29 PA
  • 14-day: .280 AVG, .382 wOBA, 24.1% K%, 4 HR, 2 SB in 54 PA
  • 30-day: .271 AVG, .357 wOBA, 21.5% K%, 6 HR, 3 SB in 93 PA

Every metric is moving in the right direction. The wOBA jump from .357 to .407 in the most recent window is significant, but what stands out most is the strikeout rate plummeting from 21.5% over 30 days to 13.8% over the last seven. That's not a small fluctuation — that's a hitter who's locked in and making better swing decisions. When contact quality goes up and strikeouts go down simultaneously, the data is clear: this isn't noise.

The Batted Ball Data Backs It Up

Gelof's 56.9% hard-hit rate over the last seven days is elite-level contact. Pair that with an 88.7 mph average exit velocity, and you're looking at a hitter who isn't just making contact — he's barreling baseballs. The 30-day hard-hit rate of 49.5% with an 89.5 mph exit velocity shows this isn't entirely a hot-streak mirage either. The underlying quality of contact has been there for a full month. The recent surge is the outcomes catching up to the skills.

Playing Time Is Secure

With 29 PA in the last seven days and 93 over 30 days, Gelof is firmly entrenched in the Athletics' everyday lineup. His multi-position eligibility at 2B, 3B, and OF adds significant roster flexibility — a quietly massive edge in leagues where lineup construction matters. He's not a platoon piece or a streaky bat riding the bench every third day. He's playing. Every day.

The Fantasy World Is Catching On

The Athletic recently highlighted Gelof as a waiver wire target, calling him a "fantasy blast from the past." That mainstream attention is exactly why ownership is accelerating. When major outlets start writing about a player we flagged three weeks ago, the free agency window slams shut fast.

Verdict: Add Now

This is real. A .407 wOBA over a solid 54 PA sample with a collapsing strikeout rate, elite hard-hit numbers, power-speed production (6 HR, 3 SB in 30 days), and locked-in playing time — Zack Gelof checks every box. At 17% rostered, he's still available in the vast majority of leagues, but that number is rising fast. Don't wait for 40% ownership to confirm what the data already tells you. Get him now.
