Early life and amateur careerEdit

Gsellman is the son of Bob Gsellman, a former minor league catcher drafted by the Philadelphia Phillies in the 23rd round of the 1984 MLB Draft from Culver City High School in California.[2][3] Gsellman attended Westchester High School in Los Angeles where he played both basketball and baseball. He was a California Interscholastic Federation state champion in basketball as a junior and voted team captain as a senior.[4][5] As a junior baseball player, he had a .649 batting average and 1.67 ERA.[4] He was also named to ESPN RISE's Underclassmen All-California team.[6] As a senior, he finished with a .608 batting average with eight home runs and a 1.70 ERA.[6] He verbally committed to Los Angeles Harbor College as a senior.[7]

Professional careerEdit

Gsellman was drafted by the New York Mets in the 13th round of the 2011 Major League Baseball draft.[8][9] He signed with the Mets and made his professional debut with the Gulf Coast Mets. From 2012 to 2015 he played for the Kingsport Mets, Brooklyn Cyclones, Savannah Sand Gnats, St. Lucie Mets and Binghamton Mets.[10] During 2015 with St. Lucie, he was named to the FSL mid-season All Star team, however, did not participate due to his promotion to Binghamton. The Mets added him to their 40-man roster after the season.[11] Also, the team announced that Robert Gsellman was named the Sterling Organizational Pitcher of The Year. For the year Gsellman went 13-7 with a 2.89 ERA in 24 combined starts for St. Lucie and Binghamton. He led the organization with 13 wins and was third in the organization in ERA among qualified pitchers.

Gsellman began the 2016 season with the Las Vegas 51s of the Class AAA Pacific Coast League.[12] The Mets promoted him to the major leagues on August 22 when Steven Matz was placed on the disabled list.[13] Gsellman made his Major League debut on August 23, 2016. Taking over for Jonathan Niese, who had left the game with left knee pain after pitching ​13 of an inning, Gsellman pitched 3 and ​13 innings, racking up 2 strikeouts, giving up no runs, and earning his first Major League win, the second Met rookie to do so in his debut in 2016, after Gabriel Ynoa.[14] Due to an injury to his labrum, Gsellman was unable to swing the bat during his 2016 Major League stint.[15] Nevertheless, on September 25 at Citi Field, Gsellman picked up his first Major League hit on a bunt off of Phillies pitcher Jake Thompson.[16]

Gsellman began the 2017 season as a member of the Mets starting rotation.[17] He was 8-7 with a 5.19 ERA. Batters reached base against him on errors 16 times, tops in the major leagues.[18]

Gsellman started the 2018 season in the bullpen for the Mets. He was 6-3 with a 4.28 ERA.
