The Los Angeles Dodgers selected the contract of left-hander Adam Kolarek from Triple-A Oklahoma City and optioned right-hander Andre Jackson.
In an additional move, the Dodgers moved outfielder Trayce Thompson to the 60-day injured list to make room on the 40-man roster for Kolarek.
Kolarek, 34, returns to the Dodgers for the first time since pitching for the club from 2019 to '20. He was 0-3 with a 2.18 ERA at Oklahoma City this season after signing with the club in December. In 170 career major league relief appearances, he is 11-4 with a 3.77 ERA for the Tampa Bay Rays (2017-19), Dodgers and Oakland Athletics (2021-22).
Jackson was just recalled Saturday and pitched three scoreless innings against the Philadelphia Phillies to earn his second three-inning save of the season. He was returned to Triple-A as the Dodgers look for more innings coverage during a planned bullpen game Sunday against the Phillies.
Jackson, 27, has a 6.62 ERA over seven relief appearances this season and is 0-1 with a 4.15 ERA in 14 career relief appearances for the Dodgers over the past three seasons.
Thompson, 32, has been on the IL since June 3 with an oblique injury. He was batting .155 with five home runs and 14 RBIs over 36 games.
According to the Orange County Register, Los Angeles right-hander Alex Reyes underwent a second shoulder surgery and will not pitch this season. An All-Star closer with the St. Louis Cardinals in 2021, Reyes did not pitch last season while having shoulder surgery. Reyes, 28, signed a $1.1 million deal with the Dodgers as he recovered before further shoulder damage was found.
