Brandon Eisert is a relief pitcher for the Chicago White Sox. In 2026 he struck out 49 batters over 44.0 innings across 40 appearances, going 3-3. His ERA of 5.52 is 32.2% higher than the league average of 4.18 — 16th of 18 on his team, and 452nd of 538 among MLB pitchers with 20+ innings. Stripping out defence, his 3.67 FIP suggests he pitched better than his ERA shows. He missed bats on 30.6% of swings (14.0% of every pitch he threw), walked 7.4% of the batters he faced and struck out 25.9%. His 0.5 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.
