Rearick was optioned to Triple-A El Paso on Sunday. Rearick scuffled mightily to begin the season, allowing four earned runs on six hits and two walks, including two home runs. He'll head to the minors in favor of Cory Mazzoni, who was recalled Sunday.

Rearick had his contract selected by the Padres on Friday and will join the big league bullpen in the short term, the Union-Tribune's Dennis Lin reports. Ian Kennedy (hamstring) was placed on the DL and Odrisamer Despaigne moved from the bullpen to take Kennedy's rotation spot. Rearick held left-handed hitters to a .136 average at Triple-A El Paso last season, and his role with the Padres will be to come in and get outs against southpaws in the middle innings.

Rearick has been reassigned to minor league camp, the Union-Tribune reports. Rearick was one of two left-handed relievers remaining in camp after Alex Torres was dealt to the Mets earlier in the week. He performed well through spring training, posting a 3.52 ERA over 7.2 innings of work. All three of his earned runs came from a single bad outing against Seattle on Sunday. He'll head down to minor league camp and likely start the season at Triple-A El Paso.
