The Red Sox have made a minor pitching transaction ahead of Tuesday's game against the Rays.
Right-hander Robert Stock has been recalled and lefty Jeffery Springs has been optioned to the alternate training site.
Stock was profiled in a recent story by WEEI.com's Rob Bradford, who noted his 100 mph fastball and also at 13 years old he was named by Baseball America as the best baseball player in the country for his age group.
He was claimed off waivers from the Phillies on July 26. Stock made his major league debut in 2018 and posted a 2.50 ERA in 32 appearances—all in relief—with the Padres. Although he made their Opening Day roster last season, he spent the bulk of the year in Triple-A.
The 30-year-old was a catcher before transitioning to pitching in 2012.
