Cespedes back in lineup, thumb sprain not an issue

ARLINGTON -- The right thumb sprain that kept Yoenis Cespedes out of Thursday's lineup was no longer an issue Friday, when the A's welcomed back their slugger to the starting lineup for the start of a three-game set against the host Rangers.

Coco Crisp was missing from it, though, because of a routine day off, so manager Bob Melvin started Cespedes in center field, with Brandon Moss manning left.

Cespedes snapped his career high-tying 25-game homerless streak with his fifth career two-homer game Wednesday and entered the day 8-for-21 with four extra-base hits since the All-Star break. He was 0-for-19 before that.

Crisp has routinely been given rest this season to offset his injury-prone ways. The 34-year-old has started just 68 of the club's 102 games.

A's could seek help at second base

ARLINGTON, Tex. -- Baseball's best team isn't flawless, but could it be with second-base help?

That's the only area the A's may look to upgrade in advance of the July 31 Trade Deadline, even though manager Bob Melvin says, "I like the team we have."

Oakland's front-office army is on the hunt for help, anyway, and at a time when Eric Sogard is finally providing production at the plate. His ability to keep it up likely won't alter their stance before the Deadline, but it's significant for the here and now.

Sogard compiled as many hits in his first 11 at-bats after the All-Star break as he totaled in his previous 35 trips to the plate, earning him a third straight start at second base Friday. He started just three other games total in the month of July.

"Sogard's starting swinging the bat here recently, and we've seen that when he plays well, he can really contribute, defensively, on the bases," said Melvin. "That's what's being bantered about out there. I don't think we necessarily have to do something there. That's just me."

The A's are also expected to welcome back Alberto Callaspo (right hamstring strain) as soon as Sunday, after he makes a rehab start with Class A Advanced Stockton on Saturday. Sogard is a candidate to be optioned when that happens.

Worth noting

• The A's on Friday acquired right-hander Deck McGuire from the Blue Jays for cash and optioned him to Triple-A Sacramento.

McGuire was 6-9 with a 4.21 ERA in 20 starts between Double-A New Hampshire and Triple-A Buffalo.

Kyle Blanks, stationed on the disabled list with a left calf strain since June 24, is still at least a week away from a rehab stint. The A's first baseman isn't expected to be sent out for one until the team returns home at the end of the month, Melvin said.

Stephen Vogt remains unavailable behind the plate because of a right foot issue but will continue to see time at first base and designated hitter.
