Jenrry Manuel Mejía (Spanish pronunciation: [ˈxenri meˈxi.a]; born October 11, 1989) is a Dominican professional baseball pitcher for the Saraperos de Saltillo of the Mexican League.

[1] Mejía later submitted an application for reinstatement, as allowed under MLB's drug policy, which was granted by Commissioner Rob Manfred in July 2018.

[2] Growing up, Mejía lived with his parents and younger brother in a neighborhood called Herrera, near Santo Domingo's former airport of the same name.

[3] When he was 15 years old, he started playing baseball, becoming interested in the sport once he realized that players were able to earn a large signing bonus.

[3] He drew some interest from several teams, including the Boston Red Sox and New York Yankees, but was not seen at that time as a top talent, because he was small and slight of build.

After the 2009 season, the Mets assigned him to the Surprise Rafters of the Arizona Fall League,[4] where he posted a 12.56 ERA in six starts.

[9] After posting a 2.60 ERA in 30 relief appearances, on June 20, 2010, Mejía was optioned to Double-A Binghamton to become a starter, with Bobby Parnell taking his spot in the Mets bullpen.

[10] On September 4, Mejía made his first major league start for the Mets at Wrigley Field against the Chicago Cubs.

He was diagnosed a few days later with a complete tear of his ulnar collateral ligament and required Tommy John surgery, which put him out of reach for the remainder of the 2011 season.

He pitched 7 scoreless innings, giving up 7 hits, striking out 7, and walking none en route to his first win of the season.

[14] In 2014, Mejía won the Mets' fifth starter role out of spring training, beating out Daisuke Matsuzaka and John Lannan.

[15] Mejía's first start and win came on April 4 at Citi Field against the Cincinnati Reds in which he went 6 innings striking out 8 and allowing 4 hits, 1 run, and 5 walks.

In the first game, Mejía gave up a run off a fielder's choice to Diamondbacks shortstop Chris Owings in the top of the 9th inning.

[20] On April 11, it was announced that Mejía was suspended for 80 games by MLB after testing positive for use of stanozolol, a performance-enhancing drug (PED).

[22] On July 28, 2015, Major League Baseball announced that Mejía had been suspended for 162 games after failing a test for stanozolol and Boldenone.

[28] On November 1, 2017, Mejía returned to professional baseball when he signed a contract to play in the Venezuela Winter League for the Navegantes del Magallanes.

[1] He subsequently made two appearances with the Dominican Summer League Mets, pitching a total of seven innings without allowing any runs.

[33] After spending spring training with Boston, he was assigned to the Triple–A Pawtucket Red Sox, and also made appearances with the Double–A Portland Sea Dogs and Low–A Lowell Spinners.

[36] Mejía returned to action in 2021, appearing in 26 games and posting a 2–3 record and 3.81 ERA with 26 strikeouts and 14 saves over 28+1⁄3 innings of work.
