Stock was optioned to Triple-A El Paso on Thursday. Stock failed to make an appearance during his most recent stint with the Padres, which lasted just one day. The right-hander was shipped to the minors to free up a roster spot for Thursday's starter, Matt Strahm, who was activated from the injured list.
Stock has been called up from Triple-A El Paso, Kevin Acee of The San Diego Union-Tribune reports. The Padres optioned Chris Paddack to High-A Lake Elsinore for rest purposes Wednesday, so Stock has been recalled in the corresponding move. The right-hander gave up six earned runs in six big-league innings this season before getting sent down in April.
The Padres optioned Stock to Triple-A El Paso on Sunday. San Diego will swap out Stock and Gerardo Reyes ahead of Sunday's series finale against the Diamondbacks for a pair of fresh relief arms in Phil Maton and Luis Perdomo. Stock surrendered runs in three of his most recent four appearances, prompting the demotion.
Stock struck out three in his 1.2 innings of scoreless relief work in the Padres' 10-3 loss against the Diamondbacks on Monday. It wasn't of any consequence in a lopsided defeat for the Padres, but Stock's performance was notable as he punched out three batters in a dominant ninth inning, needing just 12 pitches to do so. His fastball topped out at a blistering 100.6 miles per hour, and he also showcased a filthy 84-mph slider. The 29-year-old had a two-run hiccup in San Diego's March 30 game against the Giants, leaving his ERA at 6.75, but he posted a 2.56 mark over 39.2 innings last year. If he can build on Monday's strong effort, Stock could emerge as a solid contributor out of the Padres' bullpen.
Stock fired three scoreless innings while allowing a hit and striking out five in Tuesday's 6-3 loss to the Mets. Tuesday's stellar outing was a stark contrast to Stock's last appearance (four runs in less than an inning July 20). The 28-year-old is an intriguing bullpen arm based on his ability to dial his fastball up to triple digits at times (97.4 mph average). The righty has struck out 11 batters with no walks over 6.2 innings in the majors so far, but he was limited to a pedestrian 2.5 K/BB in 24 games with Triple-A El Paso. Stock should get plenty of opportunities in the Padres' bullpen as they continue to sink in the standings, but he will have to rail off a series of consistent outings before being trusted in a higher-leverage role.
