The Dodgers optioned pitcher Eric Surkamp to Triple-A Oklahoma City, one day after he absorbed 3 ⅓ innings in relief of Yimi Garcia, and recalled left-hander Ian Thomas.

Thomas last pitched on Thursday for Oklahoma City, allowing four runs on five hits in 4 ⅔ innings (100 pitches). He’s 3-1 with a 4.46 ERA in 15 combined games (five starts) with OKC and Atlanta’s minor league affiliates in Gwinnett (Triple-A) and Mississippi (Double-A).

Thomas, acquired in the May trade that sent Juan Uribe to the Atlanta Braves, has appeared in one game with the Dodgers June 2 in Colorado. He’s 0-1 with a 6.48 ERA in six combined big league games with Atlanta and Los Angeles this season.

Surkamp was charged with four runs in his Dodgers debut Monday.
