SURPRISE, Ariz. -- A's reliever Joey Devine has been sidelined for a week while dealing with right biceps soreness, manager Bob Melvin confirmed to MLB.com on Thursday.
Devine last pitched on March 8 against the Dodgers and struggled with command, walking three and surrendering four runs in just two-thirds of an inning, following scoreless outings in each of his previous two spring appearances.
According to pitching coach Curt Young, Devine threw from 100 feet on Thursday and also tossed 15 pitches from flat ground, coming out of the day feeling healthy. However, there is still no timeline for his return to games, and the oft-injured reliever's most recent setback could affect where he begins the season.
Coming into camp, it appeared injury would be the only thing preventing the 28-year-old, out of options, from landing on the Opening Day roster. Just how many more days Devine misses will determine his readiness for the season, and considering he's compiled just 2 2/3 innings this spring, the A's may decide it best to keep him in extended spring should that time be lengthy.
Back spasms interrupted Devine's season last year, his first full season since 2008 after missing the previous two while rehabbing from Tommy John surgery.
The A's, already counting on bullpen arms Brian Fuentes, Grant Balfour and Fautino De Los Santos, have several options for the other spots, including right-handers Ryan Cook, Andrew Carignan and Travis Schlichting and southpaws Jerry Blevins and Jordan Norberto, among others.
