The New York Yankees originally drafted right-handed pitcher Nick Green in the 35th round of the 2013 draft out of high school but chose not to sign. He went to Indian Hills Community College for one season before being drafted by the Texas Rangers in the seventh round of the 2014 draft and signing for a $5,000 signing bonus.
After two and a half years playing in the Rangers organization, he found himself traded to the New York Yankees along with Dillon Tate and Erik Swanson for Carlos Beltran.
Green made his professional debut in 2014 with the Arizona League Rangers where he owned a 4-3 record and a 3.83 ERA in 14 games, five starts. Over 42 1/3 innings pitched he struck out 32 batters, walked 18 and limited hitters to just a .193 batting average against.
In 2015 Green earned a promotion to the Spokane Indians of the Northwest League, the Rangers Class A Short-Season affiliate. There he struggled, going 0-3 with a 7.11 ERA over ten games, nine starts, and striking out just nine batters in 31 2/3 innings.
The 2016 season saw Green return to the Spokane Indians where in seven games hit struck out 44 batters in 34 1/3 innings and earning a 2-2 record with a 4.98 ERA. After being traded to the Yankees on August 1, he pitched in two games for the Staten Island Yankees where he struck out seven in 10 2/3 innings earning a 1-1 record with a 1.69 ERA.
The Yankees chose to promote him to the Charleston RiverDogs on August 17 where he would spend the rest of the season. With the RiverDogs, Green started three games allowed just two runs and struck out 14 batters in 17 innings. He earned three wins and a 1.06 ERA.
Green returned to the Charleston RiverDogs for the 2017 season. The right-hander went 8-9 with a 4.49 ERA over 26 starts in the South Atlantic League, including the first complete game of his career. He pitched a career-high 126 1/3 innings while striking out 112 batters.
He fared much better in the first half of the 2017 season where he was 404 with a 2.7 ERA in 13 starts. In the second half of the season, he went 4-5 with a 6.31 ERA. On May 6 he pitched a career-high eight innings in a game against the Delmarva Shorebirds, allowing just a hit while striking out nine batters on 83 pitches, 59 strikes.
