BOSTON -- The Red Sox swapped out lefties Wednesday, optioning Jalen Beeks to Pawtucket and recalling Robby Scott.

Beeks made his second appearance with Boston on Tuesday, allowing three earned runs in 2.1 innings of relief against the Rangers. He has allowed nine earned runs in 6.1 major-league innings this year, putting his ERA at 12.79.

Beeks will return to Pawtucket's rotation, where has been solid all year.

Scott has made just one appearance in the bigs this year, allowing two earned runs in 0.1 innings on June 19 in Minnesota. He owns a 3.64 ERA in 65 major-league appearances since debuting in 2016.

Scott may be sent back to Pawtucket this weekend, when Boston will need a roster spot for Brian Johnson. Johnson is expected to start Sunday after spending a few days on the disabled list with hip inflammation.
