John Perkins

Jack Perkins is an Oakland Athletics relief pitcher who started the 2026 season strong as the team's primary closer with a 1.72 FIP and 11.48 K/9 through early May. However, his performance has deteriorated significantly in mid-May. He has blown 2 saves and taken 2 losses in his last 4 outings, surrendering 5 earned runs during this stretch. Most notably, on May 15th against the Cardinals, Perkins blew a save in the 9th inning, allowing 2 runs on 3 hits including a hit-by-pitch that led to the tying and go-ahead runs. His season ERA has risen to 4.11 with a 1.24 WHIP across 15.1 innings with 3 saves and 1 blown save. While he maintains strikeout ability (21 K in 15.1 IP), his control and consistency have become concerning.
