Anthony Nunez Is Striking Out Everyone — And Nobody's Paying Attention

A 55.6% strikeout rate over the last seven days. A FIP of -0.60 in that same window. An ERA of 0.00 across 2.7 innings. Anthony Nunez is flashing elite stuff out of the Baltimore bullpen, and he's rostered in just 1% of leagues. The sample is tiny. The signal is loud.

What WaiverScout Is Seeing

We first flagged Nunez on April 8th, classifying him as a deprioritize at 0.3% ownership. At the time, the profile hadn't materialized yet. Since then, the strikeout rate has exploded — jumping from 34.5% over 30 days to 55.6% over the last seven — and the underlying skills have followed. His 7-day FIP sits at an absurd -0.60, which isn't sustainable but tells you he's been utterly dominant in a small window. The signal has strengthened enough to upgrade him to Watch.

Rolling Window Breakdown

The progression across Nunez's rolling windows tells a compelling story of an arm finding another gear:

  • 7-day: 0.00 ERA, 16.67 K/9, -0.60 FIP in 2.7 IP
  • 14-day: 3.16 ERA, 11.05 K/9, 3.45 FIP in 5.7 IP
  • 30-day: 2.34 ERA, 11.69 K/9, 2.58 FIP in 7.7 IP

The 30-day line is the one to anchor to. A 2.34 ERA with a 2.58 FIP and nearly 12 K/9 across 7.7 innings suggests the performance isn't purely luck-driven — the skills are legitimately backing up the results. And the most recent stretch has been his best work yet. That 16.67 K/9 over the last week is absurd for any reliever, let alone a 24-year-old who just made his MLB debut on March 28th, per MLB.com.

The Profile

Nunez is operating as a middle reliever in the Baltimore bullpen, according to FanGraphs, who lists his current role as Bullpen: Middle Relief. That limits his ceiling in traditional leagues — he's not getting save opportunities ahead of guys like Raisel Iglesias. But in leagues that value strikeouts, ratios, and holds, this kind of performance profile has real value.

The broader fantasy industry hasn't caught up yet. FantasyPros and RotoWire have player pages up but there's no significant buzz. This is exactly the kind of early signal WaiverScout exists to surface — before the rostership spike, not after.

The Caveats

Let's be clear: we're working with 7.7 total innings. That's an early signal, not a proven commodity. The recent game log shows some batting stats mixed in (likely pinch-hitting appearances), and the overall confidence level is low. Nunez could be a guy who settles into a 9 K/9 arm with a 3.50 ERA, which is fine but not a league-winner. Or he could be a reliever whose stuff plays up enough to maintain elite strikeout numbers. We don't know yet.

His ownership velocity is stable — the +0.6% move over seven days isn't panic-inducing. You have time. But that window narrows fast once a reliever posts a few more dominant outings on the Baltimore stage.

Verdict: Watch

Anthony Nunez is a Watch, not an add — yet. Early signs suggest he could be emerging as a high-strikeout weapon in a competitive bullpen. The 55.6% K rate and -0.60 FIP over the last week are worth monitoring closely. If you're in a deep league or a holds league, he's worth a speculative stash now. In standard formats, keep him on your shortlist. We flagged him at 0.3% ownership. He's at 1% now. If the next two weeks look anything like the last seven days, that number is going to move fast.
