Sean Gilmartin Autographs
Sean Gilmartin is a professional baseball player from California. Born on May 8, 1990, Gilmartin attended Crespi Carmelite High School and then went on to play college ball at Florida State University. In 2011, the New York Mets drafted him in the first round, 28th overall, and he made his MLB debut with the team in 2015.
Gilmartin spent his first season in the majors as a relief pitcher for the Mets, appearing in 50 games and earning a record of 3-2 with a 2.67 ERA. He pitched in the postseason that year as well, helping the Mets reach the World Series. However, the following year Gilmartin struggled and was ultimately sent down to the minors. He bounced around between the minors and majors for a few seasons before being traded to the Baltimore Orioles in 2018, where he spent the rest of the season in Triple-A.
After spending the 2019 season in Triple-A with the Tampa Bay Rays organization, Gilmartin signed a minor league contract with the Oakland Athletics for the 2020 season. He wasn't called up to the majors during the shortened season, but was re-signed to a minor league deal for the 2021 season. Throughout his professional career, Gilmartin has proven to be a reliable left-handed pitcher, able to contribute both as a starter and a reliever. Despite being known for his pitching, Gilmartin also has a strong reputation as a mentor and leader in the clubhouse.
