Aroldis Chapman continues to capture the baseball world's attention. At 37 years old, the Boston Red Sox closer is not just relying on his veteran experience—he's making MLB history with every pitch. Let's explore how Chapman is redefining what it means to be a dominant closer in today's game.

Aroldis Chapman's Incredible Fastball Streak

Aroldis Chapman has always been known for his lightning-fast pitches. In early May 2025, he delivered a 103.8 mph fastball, setting a new franchise record for the Boston Red Sox. According to Sports Illustrated, that pitch was not just the fastest ever by a Red Sox player since pitch tracking began—it was also the hardest thrown in the majors that season.

His ability to maintain this velocity is astonishing. Chapman’s average two-seam fastball speed stands at 100.6 mph, an increase from the prior season. This velocity allows him to overpower hitters and remain one of the most formidable closers in baseball.

Overcoming Career Challenges

Many assumed Chapman was past his prime after leaving the New York Yankees in 2022. Injuries, inconsistent performance, and off-field issues led to doubts about his future. But after closing out wins for the Red Sox, he's proven doubters wrong and reclaimed his reputation as a game-changer.

Chapman’s journey has included stints with the Kansas City Royals, Texas Rangers—where he won a second World Series title—and the Pittsburgh Pirates. Everywhere he’s gone, his fastball has made headlines. His perseverance is a testament to his work ethic and love for the game.

Impact on the Boston Red Sox

Chapman's contributions to the Red Sox go beyond his speed. He provides much-needed stability at the end of games. In 2025, he's been a perfect five-for-five in save opportunities and boasts a 2.19 ERA. His presence in the bullpen offers confidence to the entire team, and his leadership sets a standard for younger pitchers.
