PHOENIX -- The Arizona Diamondbacks recalled outfielder Peter O'Brien from Triple-A Reno and optioned left-handed pitcher Edwin Escobar to Reno.
O'Brien was in the starting lineup for Friday's game vs. the Marlins, playing left field and batting fifth. Manager Chip Hale said he would be a regular in the lineup, at least for the short term.
O'Brien leads all minor leaguers in home runs (17) and total bases (142), while hitting .330 with 52 RBI and a 1.025 OPS in 51 games with the Aces. In his last 10 games, he is batting .432 (19 for 45) with four doubles, five homers and 21 RBI.
O'Brien spent three games in uniform with the D-backs last month but batted just once. He played in eight games for the D-backs last September, going 4 for 10 with a home run and 3 RBI.
Escobar was 0-2 with a 14.14 ERA in two starts for the D-backs and was expected to stick with the team as a second left-hander in the bullpen.
Hale said the D-backs will call up Zack Godley to start in Saturday's game vs. the Marlins. A corresponding roster move will be made prior to the game. With only 11 pitchers on the active roster, it's likely that a position player will be moved.
