4. Corey Kluber
Goodbye and good riddance, Mr. Kluber.
Kluber signed a one-year, $10 million deal with the Red Sox last offseason, and it was immediately a disaster from Day 1. By the middle of the season he’d become unplayable, mercifully landing on the IL in late June before he could do any more damage to Boston’s season.
A two-time Cy Young winner before he joined the Red Sox, Kluber was one of the worst pitchers in baseball this year, going 3-6 with a hideous 7.04 ERA and a 1.64 WHIP in 55 innings.
Boston has a team option on him for 2024, but there’s a 0% chance it gets exercised on the 37-year-old. Kluber won’t be back next season, and frankly I’d be surprised if he’s back in the majors at all.
