Domingo Germán Polanco (Spanish pronunciation: [xeɾˈman]; born August 4, 1992) is a Dominican professional baseball pitcher who is a free agent.

He has previously played in Major League Baseball (MLB) for the New York Yankees and Pittsburgh Pirates.

Germán was signed by the Florida Marlins as an international free agent in 2009 and made his MLB debut in 2017 with the Yankees.

Just over a month later, Germán was placed on the restricted list by the Yankees after a violent clubhouse confrontation while allegedly drunk.

Domingo Germán Polanco was born on August 4, 1992, in San Pedro de Macorís, Dominican Republic.

Germán pitched for the Batavia Muckdogs in 2013, and had a 2–3 win–loss record with a 1.76 earned run average (ERA) in eight games started.

[7] On December 19, 2014, the Marlins traded Germán, Nathan Eovaldi, and Garrett Jones to the New York Yankees in exchange for Martín Prado and David Phelps.

[9] He made 10 starts split between the Single–A Charleston RiverDogs and High–A Tampa Yankees, accumulated a 3.08 ERA with 38 strikeouts across 49+2⁄3 innings pitched.

[18] On January 2, 2020, Germán was suspended for the first 63 games of 2020, making his punishment for 81 games including time served in 2019 due to violating the league's personal conduct policy, the harshest suspension levied to a player on domestic violence allegations, but not formally charged.

Against the Boston Red Sox on July 25, Germán took a no-hitter through seven innings until a lead-off double by Alex Verdugo ended the chance.

Germán's performance marked the fourth perfect game by a Yankees pitcher, the most by a single team in major league history.

On August 2, the Yankees announced that Germán agreed to voluntarily submit to inpatient treatment for alcohol abuse.

[24] It was later revealed that prior to this transaction, Germán was acting belligerent in the Yankees clubhouse where he had a confrontation with manager Aaron Boone, overturned furniture, and smashed a TV.

[28] He made 11 starts split between the Single–A Bradenton Marauders and Triple–A Indianapolis Indians, accumulating a 4–4 record and 5.13 ERA with 52 strikeouts over 54+1⁄3 innings pitched.

Sources revealed that Germán slapped his girlfriend at the event, but an investigation by Major League Baseball focused primarily on what happened at his home later that night.

According to multiple league sources, including a person with knowledge of the MLB investigation, Germán was intoxicated and became physically violent toward his girlfriend until she hid in a locked room.
