The Padres recalled Vasquez from Triple-A El Paso on Saturday ahead of his start versus Arizona.
Vasquez allowed nine earned runs over 4.1 innings during his last MLB start Aug. 31 and turned in a 7.20 ERA over 15 frames to finish the season in Triple-A, but he'll be called upon nonetheless to get San Diego through its penultimate regular-season game Saturday. On top of his poor performance, the 25-year-old will match up against a Diamondbacks offense that boasts an .818 OPS since the start of September, making him a rather unappealing streaming option. Alek Jacob was optioned to El Paso in a corresponding move.
