The Detroit Tigers selected Green in the 11th round of the 2013 MLB draft.[9] He made his professional debut that year with the GCL Tigers, and after two games, was promoted to the Lakeland Flying Tigers where he finished the year with a 3–0 record and a 3.63 ERA in 17+1⁄3 innings pitched. He pitched for the West Michigan Whitecaps in 2014[10] where he was 6–4 with a 3.11 ERA in 23 starts.

The Yankees promoted Green to the major leagues on May 14, 2016.[14] He made his major league debut on May 16.[15] After being called up as a reliever, the Yankees shifted Green to the rotation. After four starts, the Yankees shut down Green for the season when he suffered a sprained elbow ligament.[16] Green appeared in 12 games (eight starts), with a 2–4 record, 4.73 ERA and 52 strikeouts in 42+2⁄3 innings.
Green reported to spring training in 2017 as a starter.[17] Instead of naming a fifth starter, the Yankees optioned him to the minors and carried an extra reliever instead.[18] On May 8, Green was called up to the Yankees.[19] Green made his season debut with the Yankees on May 9 and was used primarily as a reliever for the season. On June 11, Green made his first start of season, a spot start, against the Baltimore Orioles. He allowed two runs in two innings, striking out three.[20] Green ended the season with a 5–0 record, 1.83 ERA and 103 strikeouts in 69 innings. He and Dellin Betances became the sixth pair of teammates to strike out 100 batters as a reliever.[21] In the first inning of the 2017 American League Wild Card Game, Green relieved Luis Severino with two runners on base after three runners had scored. Green ended the inning with consecutive strikeouts and later pitched a scoreless second inning before being taken out in the third inning. In two innings pitched, Green allowed one earned run and struck out four.[22] He finished the 2017 season with a 5–0 record, a 1.83 ERA, and a 0.74 WHIP in 40 games.[23]
Green spent the entire 2018 season with the big league club. Following the acquisition of Zack Britton on July 24, Green was pushed down in the pecking order.[24] He fell into mid-season skid where he posted a 6.75 ERA across 12 appearances. To get out of it, he reintroduced a changeup into his repertoire.[25]
Green struggled in April 2019, allowing 14 earned runs in 7+2⁄3 innings pitched. The Yankees optioned Green to Scranton/Wilkes-Barre on April 24.[26] He made his return on May 12, recording three strikeouts in the ninth inning to close out a 7–1 win against Tampa Bay Rays.[27] For the 2019 season, Green was 4–4 with a 4.17 ERA. He appeared as the Yankees' "opener" 15 times.[28] After throwing 4+2⁄3 scoreless innings in the playoffs, he allowed a three-run homer to Carlos Correa of the Houston Astros in Game 4 of the 2019 ALCS.[29] He was the team's opener in Game 5, allowing a three-run home run to Yuri Gurriel in the first inning.[30][31]
On August 28, 2020, Green allowed three home runs in one inning against the Mets.[32] He recorded a 3.51 ERA, 32 strikeouts, and 11.2 K/9 in 25+2⁄3 innings pitched across 22 appearances that year.[33] In 2021, Green posted a 3.12 ERA, 99 strikeouts, and 10.6 K/9 across 83+2⁄3 innings pitched. He had a 10–7 record, as well as a career high six saves, across his 67 appearances out of the bullpen.[34]
Green started the 2022 season recording a 3.00 ERA, 16 strikeouts, and a 1–1 record with a save across 14 appearances.[35] However, Green exited the Yankees' May 19 game against the Orioles due to right forearm discomfort.[36] Three days later, the team confirmed that Green would undergo Tommy John surgery, ending his season.[37]
Toronto Blue Jays
On January 31, 2023, Green signed a two-year, $8.5 million deal with the Toronto Blue Jays. Given that he was still recovering from Tommy John surgery at the time, the deal has a unique structure. The first year of the contract guarantees $2.25 million. After that, the Blue Jays can pick up a club option that locks him in at $27 million over three years with $1 million in performance bonuses based on innings pitched. If the team declines its option, Green can trigger a player option for $6.25 million with up to $2 million in performance bonuses for 2024. If he declines that option, then the Blue Jays can bring him back at $21 million over two years with $1 million in performance bonuses.[38][39][40] He was activated from the injured list on September 1, and made his Blue Jays debut on that same day.[41] Following the 2023 season, Toronto opted to exercise its two-year, $21 million option, after the first two options were declined.[42]
