Peralta was designated for assignment Thursday, Greg Johns of MLB.com reports.

EDGE Analysis

Peralta came on to help put out the fire Wednesday in San Diego after starter James Paxton allowed eight runs (three earned) over 3.2 innings. However, Peralta only fanned the flames as he allowed three earned runs on four hits over 1.1 innings of work. His ERA on the season ballooned nearly three full runs over the last month, finishing out at 5.40. He'll now be subject to waivers and could have some interest from teams across the league, but the 40-year old reliever is unlikely to make much of a fantasy impact the rest of the season.
