Barnes was the closer for a significant portion of the season, even taking home AL Reliever of the Month honors early in the season. In the first half of the season, he held opposing lineups to a .174/.238/.280 line and .518 OPS in 38 games. By midseason, the Sox announced that they had signed the first-time All-Star to a lucrative extension.
However, Barnes struggled to a 13.50 ERA over 11 August appearances and only made six appearances in September, due in part to a stint on the COVID IL during the team outbreak. Over those six appearances, he threw a total of five innings, struck out six, and allowed two earned runs. The Red Sox still won the games in which Barnes allowed runs, but it certainly didn’t help his case.
By season’s end, Barnes’ numbers were nearly identical to the three full seasons before the pandemic. Between 2017-2019, he had an ERA between 3.65-3.88, pitching between 62-70 appearances in each of those seasons. This year, he had a 3.79 ERA over 60 appearances, though he finished a career-high 44 games and earned 24 saves.
