Kenley Jansen

Kenley Jansen has been one of the most dominant closers of the 21st century. He surpassed 400 career saves while maintaining elite strikeout numbers during his prime. From 2011 through 2017, he was arguably baseball’s best closer. His 2017 season included a 1.32 ERA with 109 strikeouts and only seven walks. Jansen’s cutter-heavy approach drew comparisons to Rivera. His career ERA+ ranks among the best of modern closers. He delivered in high-pressure postseason situations despite a few setbacks. His consistency across more than a decade stands out. Sustained excellence secures his place inside the top ten.
