Aroldis Chapman
Chapman at 38 just turned in the best season of his career, posting a microscopic 1.17 ERA that translates to an ERA+ of 356 — meaning he was more than three times better than league average. For a pitcher who's been elite for over a decade, finding another gear this late in his career defies every aging curve in baseball.
The Cuban flame-thrower has always been about velocity and strikeouts, but his 2025 campaign with Boston represents pure mastery. His 85 strikeouts maintained the dominance that's produced 1,331 career punchouts across 821 innings, while his improved command has pushed his ERA nearly a full run below his career 2.52 mark.
Eight All-Star selections tell the story of sustained excellence, but this latest chapter suggests Chapman isn't just surviving Father Time — he's embarrassing him. The question isn't whether he can maintain this level, but how much longer he wants to prove that elite velocity paired with seasoned guile remains baseball's most lethal combination.

Each pitch type this pitcher throws regularly, placed by how the ball moves — sideways break across, rise or drop down the side. Each dotted ring holds about the middle 85% of the league’s pitches of that type, so a cluster sitting outside its ring is movement most pitchers don’t have.
The dots — a sample of this pitcher’s regular-season pitches, placed by movement: left–right is horizontal break, up–down is induced vertical break (what the pitch does beyond gravity). The view is handedness-neutral — positive break is toward the pitcher’s arm side for lefties and righties alike, so every sinker runs right and every sweeper breaks left, whoever throws it.
The dotted rings — about the middle 85% of where each pitch type lands league-wide (a 2-standard-deviation spread), measured from 7.5 million regular-season pitches since 2015. A cluster sitting well outside its ring is movement most of the league doesn’t get. Spring training and the postseason are excluded.
