Hatcher was sidelined since late June with thoracic inflammation. He finished up a minor league rehab assignment this week with Triple-A Oklahoma City. In a total of five games between rookie-level Arizona and Triple-A, Hatcher allowed one run on four hits in six innings, with nine strikeouts and one walk.
The right-hander last pitched on Wednesday, throwing a scoreless inning for OKC on the second of back-to-back nights.
In 26 games with the Dodgers this season, Hatcher has a 4.66 ERA and 4.26 FIP in 26 games, with 43 strikeouts and 12 walks in 36⅔ innings. Hatcher has mostly been limited to non-important situations, with the lowest average leverage index among pitchers on the staff with at least five relief appearances.
To make room for Hatcher, the Dodgers optioned catcher Kyle Farmer to Triple-A. Farmer appeared in 10 games for the Dodgers, going 4-for-10, including a walk-off double in his major league debut on July 30 against the Giants.
Farmer didn’t see any time behind the plate in his first major league stint, but did play two innings at third base.
