Joel Kuhnel: The Strikeout Spike Is Real, But Patience Is Required

Joel Kuhnel's strikeout rate has surged to 23.5% over the last seven days, up from 17.0% over the past 30 — and paired with a 1.85 FIP in that window, the Athletics reliever is flashing the kind of skills profile that demands attention. WaiverScout is upgrading him to Watch status after previously classifying him as "deprioritize" in five consecutive signals dating back to April 11.

What Changed

Let's be blunt: Kuhnel was unrosterable for most of April and early May. We flagged him as deprioritize when he was rostered in 27% of leagues on April 22, again at 21% on May 1, again at 14% on May 9, and twice more after that. Ownership has cratered to just 9%, and most managers have moved on. That's exactly the kind of environment where an early signal can turn into a league-winning pickup — if the skills are real.

The rolling numbers tell a compelling story of improvement:

  • Last 7 days: 0.00 ERA, 9.0 K/9, 1.85 FIP across 4 IP
  • Last 14 days: 3.00 ERA, 10.5 K/9, 3.43 FIP across 6 IP
  • Last 30 days: 2.08 ERA, 6.23 K/9, 3.87 FIP across 13 IP

That FIP trajectory — from 3.87 to 3.43 to 1.85 — is the number that matters most. ERA can lie over small samples. FIP strips away the noise and isolates what the pitcher is actually doing with strikeouts, walks, and home runs allowed. A 1.85 FIP over any window, even a small one, tells you the underlying performance has been legitimately elite.

The Caveats Are Obvious

We're working with just 4 innings in the 7-day window and 13 innings over 30 days. This is an early signal with limited confidence, and anyone claiming certainty here is selling you something. The K/9 jump from 6.23 to 9.0 to 10.5 (in the 14-day window) early signs suggest something mechanical or pitch-mix related may have clicked, but it could also be a hot stretch against weak lineups.

It's also worth noting that Kuhnel signed a minor league deal with Oakland in December 2025, per MLB.com, and worked his way up through Las Vegas. This isn't a prospect with a pedigree — he's a journeyman reliever who has to earn every opportunity. RotoWire didn't even publish a 2026 outlook for him, and Pitcher List has his data available but he's hardly generating mainstream buzz. This player isn't on anyone's radar yet — which is precisely the point.

Ownership Window

At 9% rostered with stable velocity in ownership trends, Kuhnel is freely available in virtually every league. He's not competing for FAAB dollars against names like Mason Miller or Raisel Iglesias. He's a zero-cost speculative add — or in this case, a zero-cost watch-list addition.

Verdict: Watch

WaiverScout is not recommending a pickup yet. The sample is too thin and our confidence level reflects that. But the trend reversal is undeniable: five consecutive deprioritize flags followed by a legitimate skills spike deserves respect. If Kuhnel maintains this strikeout rate and FIP over another 5-7 appearances, he could be emerging as a viable fantasy reliever in deeper formats. Add him to your watch list now, check back in a week, and be ready to move before the 9% ownership number starts climbing. The best waiver adds are the ones you see coming.
