There was no corresponding move, but right-handed reliever Neil Wagner, acquired via trade from the Indians last year for cash, is expected to be selected from Triple-A on Tuesday and join Oakland's bullpen to fill out the active roster. Wagner has not yet appeared in a Major League game.
The club has to wait a day to make the transaction because lefty Jerry Blevins -- designated for assignment on Saturday -- needs to clear waiver options before a spot on the 40-man opens. Though that will happen Tuesday, it doesn't mean Blevins will be taken off the roster. The A's could choose to transfer Daric Barton (right shoulder) to the 60-day disabled list.
Wagner, who has quietly posted impressive numbers with Sacramento since his promotion from Double-A on June 25, would be the 14th relief arm used by the A's this year. He is 2-1 with a 3.10 ERA in 22 appearances for the River Cats and has compiled 34 strikeouts in 29 innings.
Godfrey's move was expected, as he was recalled following the first game of Saturday's doubleheader in Boston to start the second contest. He took the loss, allowing three runs on six hits in four innings before an hour-long rain delay ended his night.
Overall, the righty is 1-2 with a 4.71 ERA in four starts with the A's this year.
"It's about getting the opportunity and consistent chance at the big league level," manager Bob Melvin said. "He definitely has the stuff to be able to do it. It's just refining it and maintaining consistency with it."
