Luis Perdomo

Perdomo won a spot in the Padres' 2018 starting rotation. On April 11 of that year, in a game against the Colorado Rockies, Perdomo threw a pitch behind Nolan Arenado, causing Arenado to charge towards Perdomo. Perdomo flung his glove at Arenado and dodged in a split second to avoid the tackle, leading to a bench-clearing brawl. On April 13, Perdomo was suspended for five games. He was placed on the disabled list on July 28 with a right shoulder strain. He ended the season 1–6 in 12 appearances (10 starts). He had an ERA of 7.05 in ​44  ⁄3 innings. In 2019, Perdomo pitched exclusively out of the bullpen, totaling 47 appearances while making just 1 start. He was 2-4 with an even 4.00 ERA.

Perdomo was named the Padres fifth starter coming out of Spring Training in 2017. After missing some time with a sore shoulder in April, Perdomo remained in the starting rotation for the remainder of the year. He posted an 8-11 record and a 4.67 ERA in 29 starts, with 118 strike-outs in 163 ​⁄3 innings pitched. He was 3rd on the club in innings pitched, behind Clayton Richard and Jhoulys Chacín, and led the National League in ground ball rate.

As a Rule 5 selection, Perdomo was added to the Padres bullpen for 2016 despite being hit hard in Spring Training and never having pitched above the A-Advanced level. He was moved into the rotation in June as the Padres lost other starting pitchers to trades or injuries. On August 28, he threw his first complete game, earning a 3–1 victory over the Miami Marlins. Perdomo finished the season with a 9-10 record and a 5.71 ERA, although he improved over the season and had a better ERA as a starter (4.85) than as a reliever (9.10).

Perdomo was selected by the Colorado Rockies in the 2015 Rule 5 draft, and then traded to the San Diego Padres for a player to be named later or cash considerations.

Perdomo signed with the St. Louis Cardinals as an international free agent in November 2010. He made his professional debut in 2011 with the Dominican Summer League Cardinals. After spending 2012 and 2013 with Rookie League clubs, in 2014 Perdomo made 2 starts with the Class A-Short Season New York–Penn League State College Spikes and 11 starts with the Class A Midwest League Peoria Chiefs, putting up a 4.43 ERA between the two levels. In 2015, Perdomo started the year with the Chiefs. He was named the Cardinals Minor League Baseball Pitcher of the Month for May, posting a 1.42 ERA and striking out 33 in 31 ​⁄3 innings. In July, he was the Cardinals representative at the All-Star Futures Game, taking the place of the injured Alex Reyes. After posting a 3.68 ERA in 17 starts with the Chiefs, Perdomo was promoted to the Class A-Advanced Palm Beach Cardinals in August, where he made 5 starts and had a 5.13 ERA.
