 Biographical Information
Jhan Marinez debuted in the majors at age 21.
Marinez, who is often mistakenly called "Martinez", was signed by scout Sandy Nin for the Florida Marlins at age 17. He made his pro debut with the 2006 DSL Marlins, going 2-1 with a save and a 7.00 ERA but walking 26 and throwing 8 wild pitches in 36 innings. He split 2007 between the DSL Marlins (2-3, 4.70, 25 K, 19 BB, 14 H in 23 IP) and GCL Marlins (5 R in 3 1/3 IP). In 2008, he was 1-1 with a save and a 6.11 ERA for the GCL Marlins, giving out 14 walks in 17 2/3 innings.
Moving up to the Jupiter Hammerheads in 2009, Jhan made major strides, going 1-1 with a save and a 3.14 ERA while allowing a .185 opponent average. He quickly rose through the ladder in 2010, pitching for Jupiter (0-1, 4 Sv, 1.48, 41 K in 24 1/3 IP) then the Jacksonville Suns (1-0, 4 Sv, 2.30, 19 K in 15 2/3 IP). That earned him a shot at the big leagues, replacing Dan Meyer.
In his MLB debut on July 16, 2010, Jhan relieved Taylor Tankersley in the 7th inning with a 4-0 deficit and two out in a game against the Washington Nationals. He got Cristian Guzman to fly out, then was pinch-hit for by Mike Lamb. he pitched 4 times for Florida, all in relief, with a record of 1-1 and a 6.75 ERA in 2 2/3 innings. He then did not return to the big leagues until 2012, when he appeared in two games for the Chicago White Sox and did not allow a run in 2 2/3 innings.
It was not until 2016 that Jhan faced big league batters in a regular season game again. After bouncing around several organizations, he had been pitching in the Tampa Bay Rays system for a little over a year when he was called up on April 24th. he made three relief appearances, and in spite of doing well (2 hits and 1 run in 3 2/3 innings), he was designated for assignment in early May, at which point the Milwaukee Brewers purchased his contract. That turned out to be a blessing, as the Brewers actually had some use for him, and he began to pitch regularly out of their bullpen, finally seeing regular playing time six years after making his debut.
