This Eephus League Baseball scorebook was signed by Sean Doolittle in 2012, while he was with the Athletics and they were visiting Cleveland for a three-game weekend series.
Doolittle has had a great career. Since making the majors in 2012, he has had four seasons of at least 22 saves, led the league in games finished in 2019 (55!), selected to two All-Star teams and was on the World Series winning 2019 Washington Nationals. He owns a career 3.23 ERA/129 ERA+/1.024 WHIP. Doolittle is more than likely entering the twilight of his career, but even in 2021 he was still a solid arm who ended the season with more strikeouts (53) than innings pitched (49.2).
