The Oakland A’s are swapping a fresh arm into their bullpen.
The A’s called up pitcher Adam Oller on Thursday, the team announced. To make room on the active roster, lefty reliever Sam Selman was optioned to Triple-A Las Vegas.
This is the third time we’ve seen Oller in the majors this year. He cracked the Opening Day rotation and made three starts in April, then briefly returned in May to start one half of a doubleheader. However, this time around he “is going to pitch out of the bullpen, likely long relief,” reports insider Martin Gallegos.
