Crisp to miss several days with neck strain

ANAHEIM -- A's outfielder Coco Crisp was missing from Sunday's lineup for a second consecutive game because of a neck strain and will remain out "a few days," according to manager Bob Melvin.

Like he did at the beginning of the month, Crisp could potentially receive several trigger point injections to help treat the neck issue once the club returns home. No matter the length of his recovery, he won't need to go on the disabled list with 25-man rosters expanding Monday.

Crisp aggravated his neck while making a stellar effort to rob the Angels' Chris Iannetta of a homer in Friday's game.

Sam Fuld and Craig Gentry will continue to alternate in center field in his stead.

Worth noting

• Shortstop Jed Lowrie (fractured right index finger) is expected to be activated off the disabled list in time to start Monday's series opener against the Mariners at the Coliseum.

Lowrie is among several players who will join the club, with rosters expanding Monday for the final month of the regular season. The A's are anticipating to call up a handful of Minor Leaguers, none of whom were named Sunday since they had yet to be informed.
