                    Control continues to be a major issue for Chapman, who issued 39 free passes over 61.2 innings with the Pirates in 2024. His 14.7 percent walk rate was the worst among qualified relievers, but he still posted an impressive 22.3 K-BB percentage that was a top-25 mark. The veteran southpaw averaged 99.8 miles per hour on his sinker, inducing a 32 percent whiff rate that is consistently near the top of the leaderboard for that pitch type. He struck out 98 batters and racked up 14 saves, proving he can still get the job done in the ninth inning. Chapman, who will turn 37 years old in February, signed a one-year, $10.75 million deal with Boston. He'll be a candidate to close for the Red Sox alongside Liam Hendriks and Justin Slaten.

                  Picks up four-out save
Chapman gave up three hits while striking out two batters across 1.1 scoreless innings to record the save in Tuesday's 3-1 win over the Yankees. He did not issue a walk.
                  Analysis
With Boston up two runs entering the bottom of the ninth, Chapman made things interesting by allowing three consecutive singles to Paul Goldschmidt, Aaron Judge and Cody Bellinger to begin the inning. The veteran reliever then retired the next three batters he faced to preserve the win and secure the 11th postseason save of his career. After posting a career-best 1.17 ERA and 0.70 WHIP during the regular season, Chapman is a safe bet to receive the vast majority of save opportunities for the duration of the BoSox's postseason run.

Stat Review
    
                How does Aroldis Chapman compare to other relievers?
            
            This section compares his stats with all relief pitcher seasons from the previous three seasons (minimum 30 innings)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.
* Exit Velocity, Barrels/BBE %, Balls Hit 95+ MPH %, and Spin Rate are benchmarked against 2019 data (min 30 IP). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

		            Chapman finished with 100-plus strikeouts for the fifth time in his career, but for the first time since 2015. The veteran showcased increased velocity early in the season, hitting 103.8 mph on the radar gun with his devastating sinker (101.1 mph average) that yielded a 43.3% whiff rate, the league's highest mark for that pitch type. Walks were still an issue, but Chapman still had the third-highest K-BB percentage among qualified relievers at 26.9%. Ultimately, the southpaw proved he was effective enough during his age-35 season to maintain a high-leverage role for both Kansas City and Texas. Chapman only had six saves last year, and it seems unlikely that he will take away closing duties from David Bednar after signing a one-year deal with the Pirates in January. The Cuban Missile can still be an asset in leagues scoring holds, NL-only formats and even deep mixed leagues for his ratios and strikeouts.

Latest Fantasy Rumors
     
                  Wins accolade in American League
Chapman has been named the American League Reliever of the Month for August, Jason Foster of MLB.com reports.
                  Analysis
Chapman didn't allow a single hit in any of his 12 outings in August, covering 11 innings. He surrendered only one walk, during an Aug. 19 outing against the Orioles, but other than that, he was perfect. Some additional proff of how unhittable Chapman was in August was that opponents had an average exit velocity of just 84.4 mph when putting the ball in play. Chapman hasn't blown a save since July 23, with his 28 saves this year being his highest total since 2021.
