Francis Martes is a relief pitcher for the Houston Astros. In 2017 he struck out 69 batters over 54.1 innings across 32 appearances, going 5-2. His ERA of 5.80 was 33.0% higher than the league average of 4.36 — the second worst on his team, and 450th of 527 among MLB pitchers with 20+ innings. Stripping out defence, his 4.45 FIP suggests he pitched better than his ERA shows. He missed bats on 30.5% of swings (13.6% of every pitch he threw), walked 12.4% of the batters he faced and struck out 27.7%. His 0.2 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.
