Before taking on the Rays in the second of a four-game series at Fenway Park on Tuesday night, the Red Sox have recalled right-hander Robert Stock from the club’s alternate training site in Pawtucket and in a corresponding move, optioned left-hander Jeffrey Springs to that same alternate training site.
Stock. 30, was originally claimed by Boston off waivers from the Phillies late last month after he was designated for assignment by Philadelphia on July 23.
Prior to this year, the University of Southern California product appeared in 42 games for the Padres across the 2018 and 2019 seasons, posting an ERA of 4.11 and FIP of 3.27 over 50 1/3 total innings pitched. His rookie campaign was much more effective than his sophomore one, though.
While working out at the Sox’ alternate training site at McCoy Stadium, Stock fanned a pair and reached 100 mph with his four-seam fastball in a sim game appearance over the weekend.
Per Statcast, the former second-round pick of the St. Louis Cardinals back in 2009 works with a four-seamer, slider, changeup, and sinker. The average velocity of his heater this past season was 97.9 mph.
If Stock gets into a game during this series against the Rays, I would expect it to come in a low-leverage situation. Of course, he’ll likely be available to work in Thursday’s bullpen game.

As for Springs, the 27-year-old southpaw was sent down to Pawtucket less than 24 hours after surrendering three runs on five hits in just 1 1/3 innings of relief against Tampa Bay on Monday.
Through his first four appearances with the Red Sox after making his first career Opening Day roster, Springs owns an unsightly 15.43 ERA and 1.164 OPS against over 4 2/3 innings of work.

With Springs now in Pawtucket, the Red Sox currently have two left-handed pitchers on their 28-man roster, and one of them is Martin Perez. Perhaps Darwinzon Hernandez and Josh Taylor are close to returning.
