The Red Sox made a roster move Tuesday in the wake of going through six relievers in Monday’s 113-12 victory over the Blue Jays, recalling lefthanded pitcher Fabio Castro from Triple-A Pawtucket and optioning righthander Scott Atchison.
The 25-year-old Castro was a starter for Pawtucket this season, going 0-1 with an 8.10 ERA.
Atchison has a 6.10 ERA with the Red Sox this season in seven appearances over 10 1/3 innings.
The team faces a Friday deadline to decide whether to promote lefthanded reliever Alan Embree from Pawtucket. The 40-year-old has indicated he will exercise an out clause in his contract if not called up by Friday.
Embree has been excelling with the PawSox. In his last five outings, he has pitched five scoreless innings and has not allowed a hit or walk while whiffing three.
