The Los Angeles Dodgers optioned right-hander Michael Petersen to Triple-A Oklahoma City and outrighted left-hander Jose Hernandez to the minor leagues on Thursday.

The moves could allow the Dodgers to activate right-hander Joe Kelly to the active roster. Kelly, who has not pitched since May 5 because of a right-shoulder strain, has made five rehab appearances in the minor leagues with manager Dave Roberts saying his return is imminent.

Petersen, 30, made his major league debut June 18 and went 3-0 with a 4.50 ERA in nine appearances.

Hernandez, 26, was acquired from the Pittsburgh Pirates on June 13 in a cash deal, with his outright taking him off the 40-man roster after not pitching for the club. Kelly is on the 60-day injured list and would need a 40-man spot in order to return to the active roster.

Kelly, 36, had a 4.73 ERA in 15 relief appearances for the Dodgers earlier this season.

The Dodgers also are close to seeing left-hander Clayton Kershaw make his season debut after offseason shoulder surgery, while right-hander Brusdar Graterol (shoulder) also is close to making his season debut.
