Domingo German was signed by the Florida Marlins as an international free agent out of San Pedro de Macoris, Dominican Republic in 2009. German was only 17 years old at the time, and he signed for $40,000. He opened last season as the New York Yankees #45 prospect, but he enters the 2018 season as the team’s #17 prospect according to Pinstriped Prospects.
German spent five years in the Marlins organization before being acquired by the New York Yankees on Dec. 19, 2014, in a trade that sent Martin Prado and David Phelps to the Marlins in exchange for Nathan Eovaldi and Garrett Jones — in addition to German. At the time of the trade, MLB.com had ranked German as the Marlins’ No. 8 overall prospect.
German spent his first two seasons playing professional baseball for the Dominican Summer League Marlins. In 2010, he appeared in 18 games out of the pen and pitched to a 3.69 ERA over 46.1 innings. He finished with 43 strikeouts, 27 walks, and a 1.21 WHIP. He followed that up in 2011 by appearing in eight games (six starts) and finished with a 1.82 ERA over 34.2 innings where he fanned 40, walked 13, and posted a 1.47 WHIP.
In 2012, German arrived in the US and opened the season in the Gulf Coast League (GCL). In 13 relief appearances that year, German struggled with his command as he walked 16 and surrendered 17 hits in 22.1 innings pitched. He did, however, strike out 29 and posted a 1.61 ERA and 1.48 WHIP.
German started the following year back in the GCL, but his improved performance earned him a mid-season promotion to the New York-Penn League where he continued to shine. German finished 2013 (combined) with a 1.61 ERA in 13 games (all starts) where he struck out 61 and walked only 10 over 67 innings and posted an astounding 0.87 WHIP.
German was promoted once again the following year and opened the 2014 season with the Class-A (Low) Greensboro Grasshoppers. German started 25 games for the Grasshoppers and dominated over 123.1 innings to the tune of a 2.48 ERA where he struck out 113 batters and averaged only a single BB per-nine-innings. He finished the year with a 1.14 WHIP and a 3.26 FIP. German was also selected to the 2014 All-Star Futures Game where he pitched a scoreless inning and struck out two of baseball’s highly regarded prospects at the time: Kris Bryant and Joey Gallo.
After being acquired by the Yankees, German missed the entire 2015 season after undergoing Tommy John surgery.
German was non-tendered by the Yankees on Dec. 3, 2015 in a move that appeared to be strategic for New York one day ahead of the Rule 5 draft. Had he been listed on the team’s 40-man roster he would not have been protected and most likely would have been taken by another team. Instead, the Yankees re-signed German on Dec. 11 to a Minor League contract.
German began his 2016 campaign with the Class-A (Low) Charleston RiverDogs. In five starts in Charleston, German looked like his old self as he struck out 18 batters and walked just two over 26 innings while surrendering only nine earned runs (3.12 ERA) and posting a career-best 0.65 WHIP. Those numbers earned him a promotion to the Class-A (Advanced) Tampa Yankees on July 24, 2016.
German continued his dominance in Tampa: pitching to a 3.04 ERA in five starts (23.2 IP) where he struck out 20, walked nine, and finished with a 1.48 WHIP.
German was invited to Major League Spring Training and appeared in two games there. He tossed three shutout frames with the big league club where he surrendered just two hits, struck out four, and walked one.
German was then optioned to the Double-A Trenton Thunder on Monday (3/13) and reported to minor-league camp.
German opened the season in Trenton and after posting a 3.00 ERA in six starts, he was promoted to Scranton on May 18. In 14 games with the RailRiders, German went 7-2 with a 2.83 ERA in 76.1 innings. Over that span he struck out 81 while walking only 22 and finished with a 1.06 WHIP.
German was recalled to the big leagues four different times throughout the season – including a late September call-up – and he appeared in seven games with the Yankees. In that time, he threw 14.1 innings and posted a 3.14 ERA while only giving up 11 hits with 18 strikeouts and a 1.40 WHIP.
