Casey Fien has been activated from the disabled list by the Dodgers, who optioned Brock Stewart to Triple-A Oklahoma City to make room on the roster.
Fien went on the DL on July 19 with elbow tendonitis, following a stretch in which he allowed six runs (including four home runs) in 3 2/3 innings. Before that, Fien had a 1.96 ERA with 16 strikeouts in 18 1/3 innings as a Dodger.
Stewart allowed a run in three innings after relieving Brett Anderson in the second inning Sunday against Pittsburgh. It was Stewart’s first big-league relief appearance after two starts.
The Dodgers also released Zach Walters, who had been designated for assignment Sunday.
