Left-hander Wandy Peralta and not Canning will be the Padres' starter against the Dodgers on Saturday.
Canning was originally slated to start Saturday, but he'll now serve in a piggyback role after Peralta tosses one or two innings to open the contest, per Jeff Sanders of The San Diego Union-Tribune. Canning has struggled on the mound this season with a 7.09 ERA, 1.66 WHIP and 46:28 K:BB across 47 innings in 11 appearances (nine starts).
