The Boston Red Sox defeated the Baltimore Orioles 3-1 on Sunday afternoon to complete the four-game sweep of Baltimore and effectively end their playoff hopes. Boston's All-Star closer Aroldis Chapman logged the 33rd save of his season and the 400th of his 17-year career, becoming just the ninth pitcher in major league history to reach the mark. 

Chapman took the mound with the Boston clinging to a two-run lead in the ninth inning and made light work of the top of the Baltimore lineup. Orioles second baseman Blaze Alexander led things off, battling to a 2-2 count before flying out to left fielder Jarren Duran. After falling behind Baltimore slugger Pete Alonso 1-0, the All-Star first baseman ripped a single to left, giving Baltimore a glimmer of hope. However, Chapman quickly shut things down, striking out both designated hitter Coby Mayo and third baseman Christian Encarnacion-Strand on 10 total pitches to lock down the save. 

Chapman becomes just the third active player to reach 400 saves, joining a pair of former Boston closers, Craig Kimbrel and Kenley Jansen. 

Overall, the 38-year-old has continued to defy Father Time in a Red Sox uniform, posting a 2.03 ERA in 48.2 innings of work, going 33-for-35 in save opportunities en route to his ninth career All-Star appearance. 

Reaching 400 saves is just the latest in a long line of accomplishments that the closer has achieved in 2026 as he continues to mount his Hall of Fame case. In the Red Sox' May 18 win over Kansas City, Chapman logged the 378th save of his career, passing former Minnesota Twins closer Joe Nathan for 10th most saves ever. Chapman again moved closer to Mariano Rivera's record-setting 652 saves on July 24, as he recorded his 390th career save, passing former Red Sox pitcher and Hall of Famer Dennis Eckersley for the ninth-most in history. 

The 38-year-old also became the all-time strikeout leader among relief pitchers, recording the 1,364th punchout of his career in the Red Sox's Fourth of July victory over the Los Angeles Angels, passing Hall of Famer Hoyt Wilhelm. 

The Red Sox will look to make it five straight wins in a Labor Day Monday matinee as they welcome the Los Angeles Angels to Fenway Park for a three-game set. Grayson Rodriguez (4-6, 6.03 ERA) will get the start for the Angels, while the Red Sox have not yet officially named a starter; Brayan Bello is expected to work in either a bulk relief role or as a traditional starter. First pitch from Fenway is set for 1:35 p.m. ET.
