Kumar Rocker is a starting pitcher for the Texas Rangers. In 2026 he struck out 138 batters over 148.0 innings across 30 appearances, 27 of them starts, going 6-11. His ERA of 4.38 is 4.8% higher than the league average of 4.18 — 10th of 16 on his team, and 323rd of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 4.31 FIP suggests the ERA was no fluke. He missed bats on 26.1% of swings (12.5% of every pitch he threw), walked 9.5% of the batters he faced and struck out 21.4%. His 1.4 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.
