Jack Perkins | Fantasy Outlook

Jack Perkins struggles with ratios despite high strikeout upside in Oakland's bullpen.

Jack Perkins has endured a rough stretch for the third-place Athletics, posting a bloated 9.12 ERA and 1.49 WHIP over his last 30 days despite an impressive 18 strikeouts in 14.8 innings. While Oakland deployed him as a key high-leverage arm earlier in the spring, his recent struggles have caused his fantasy rostered percentage to plummet from 34% in early May down to just 6%.

Perkins' elite strikeout stuff—yielding a superb 12.32 K/9 this season—flashes high upside, but his 6.95 ERA and 1.44 WHIP in 2026 are a far cry from his solid 4.24 ERA and 1.18 WHIP from last year. Given the severe ratio damage he is currently inflicting, our models suggest fantasy managers should expect regression toward his career baselines before trusting him in active lineups.

Looking at the week ahead, the Athletics have an empty weekly projection for Perkins with no scheduled appearances locked in, suggesting a highly unstable schedule. Because of his current ratio risk and lack of guaranteed save opportunities, he is not a viable option for active rosters right now. Verdict: Sit.
