Right-handed pitcher Adonis Rosa signed with the New York Yankees as an International Free Agent on December 19, 2013.  Rosa, 22, is an under-the-radar prospect in the system and while he doesn’t get the attention like some other prospects he has proven to be a solid contributor to any team he is on.


In his first professional season in 2014, Rosa was assigned to the Dominican Summer League Yankees.  In the DSL, he earned a 1-0 record with a 1.62 ERA striking out 31 batters in 39 innings of work.  That season opponents .232 against him and he had a WHIP of 0.95.

Rosa did not allow a run in five games on the road that season in 16 innings in five games.  At home, he had a 2.74 ERA in 7 games and 23 innings.  He did not pitch more than four innings a game that season with most of his appearances being three innings which are not uncommon in the DSL.


Rosa earned a promotion to the Pulaski Yankees of the Appalachian League in 2015, by passing the Gulf Coast League.  With Pulaski, he earned a 7-2 record with a 3.93 ERA in 11 starts, striking out 42 batters over 55 innings.


Adonis Rosa started the 2016 season in extended spring training before reporting to Staten Island to start the New York-Penn League season in June.  Rosa was the opening day starter for the Staten Island Yankees, allowing two runs over six innings and striking out six Cyclones.  He went on to earn a 2-1 record with a 1.32 ERA in six games, five starts, striking out 27 over 34 innings with the Baby Bombers.

His strong performance earned him a promotion to the Charleston RiverDogs on July 22, 2016.  With the RiverDogs he earned a 2-5 record with a 2.86 ERA in eight starts.  He struck out 46 over 44 innings.  He ended his season with a six-inning shutout on September 1 against Hagerstown.

Rosa split the 2017 season between three different teams, including a brief two-game cameo in Triple-A with the RailRiders.  Overall he had an 8-3 record with a 3.06 ERA and 102 strikeouts in 111 2/3 innings pitched over 26 games, 13 starts.

He spent the majority of the season with the Single-A Charleston RiverDogs of the South Atlantic League where he was 4-3 with a 3.04 ERA in 21 games, 8 starts, striking out 79 batters in 83 innings pitched.  He had three games with the Tampa Yankees, winning all three and pitching to a 4.32 ERA with 16 strikeouts in 16 2/3 innings.

In his two games in Triple-A, Rosa allowed just two earned runs in 12 innings of work, striking out seven.


Rosa opened the 2018 season with the Tampa Tarpons, spending the majority of his season with the team where he was 12-3 with a 3.84 ERA in 20 games, 15 starts, and e struck out 89 batters in 96 innings pitched.

He was promoted to the Thunder in August, where he started just two games for Trenton, earning a 0-2 record with a 4.63 ERA and five strikeouts in 11 2/3 innings.  On August 30, the Yankees promoted Rosa once again to Triple-A where he was 2-1 with a 3.92 ERA in four games for the RailRiders.  He struck out 14 batters in 20 2/3 innings.

Overall, Adonis Rosa went 14-6 with a 3.93 ERA in 26 games, 21 starts, with 108 strikeouts in 128 1/3 innings.  He led the entire Yankees organization with 14 victories and was third in the organization in innings pitched.  His 128 1/3 innings was a career high for him, as he heads into an offseason where he will be eligible for the Rule 5 draft.
