Dodgers optioned RHP Michael Petersen to Triple-A Oklahoma City.
Peterson compiled a respectable 4.66 ERA, 1.24 WHIP and 6/5 K/BB ratio across 9 2/3 innings (six appearances) in his first taste of the majors after being called up back in mid-June. The unheralded 30-year-old righty figures to return in a couple weeks, if the opportunity is still there in Los Angeles.
