Former Yankees Closer Turns Career Around with Rival Club

Chapman defected from Cuba and made his way to the United States, where he became a star with the Cincinnati Reds. The big lefty’s adversities continued, as he was faced with a severe injury after being hit in the head with a line drive back to the mound. 

He then signed a huge deal with the Yankees in 2015 and became a superstar.  The left-hander spent seven total seasons with the Yankees in two stints. Some were memorable, some were forgettable. 

Chapman’s last few seasons in the Bronx were not ones to remember. It is now 2025, and he is reborn as a trustworthy closer in Boston. 

From the Bronx to Boston: Aroldis Chapman’s Career Resurgence

Aroldis Chapman was a three-time All-Star with the Yankees. His role as a closer was solidified, and in all three of those All-Star seasons, Chapman recorded 30-plus saves. Where did things go downhill? Well, in two instances: when hitters figured out his pitch repertoire, and when his maturity got in the way of his performance.

Chapman was a rocket fastballer, which is why he was labelled a “missile.” He got up to 102 mph, and stayed almost consistently in the triple-digits. At one point, it seemed that his sole reliance was on his velocity, which didn’t last long. 

102 mph in was 111 mph out, if caught flat in the zone, which was typically the case. In 2021 and 2024, his hard-hit percentage was over 40%.

Command was also an issue for the left-hander, as wild pitches and bases-on-balls were consistent. Chapman maintained a walk percentage above 14% for five seasons dating back to 2018. 

He was not only with the Yankees in this span, but also spent time with the Texas Rangers, Kansas City Royals, and Pittsburgh Pirates. 

Chapman’s maturity was testing the Yankees organization. The structured environment was breached many times by immature and selfish decisions by Chapman. The closer got a tattoo in-season, which caused an infection, disallowing his activity. 

He was also defiant, deciding to skip mandatory team workouts based on his own thought process. Chapman was later disregarded and put up on the trade market. Fast forward to the present day, where Chapman closes for the Boston Red Sox, and has made changes. 

Chapman’s Present-Day Self is Valuable 

Now 37 years of age, Chapman’s overall character has leveled out to be a competitor, good teammate, and effective closer. He has been kept in line by a strict Red Sox environment. His performance has followed suit as well.

From 2018 to 2024, Chapman’s walk rate averaged around 14%. In 2025, he currently holds a 7% rate, slashing that average in half. 

He maintains his velocity, increasing up to 105 mph and clocking consistently at 103 mph. Age has not ruined this feature. Chapman has improved his repertoire, commanding the fastball better, staying in and out of the zone. 

He also incorporated a splitter and is utilizing his sinker and slider more effectively. Chapman currently holds a 1.04 ERA with 26 saves, 74 strikeouts, 14 walks, and a 4-2 record in 52 innings pitched. 

The southpaw closer has revived his profile and is in the running for a postseason opportunity on the dark side (for Yankees fans, anyway) of the American League East.
