OAKLAND -- A day after collecting five RBI on two home runs in a game he left early due to injury, Yoenis Cespedes is not in the lineup for Thursday afternoon's series finale against the Houston Astros.
He is, however, available off the bench, and manager Bob Melvin is hopeful the slugger will be able to start Friday night in Texas.
X-rays came back negative after Cespedes sprained his right thumb when it took the brunt of a fall he braced for with both hands.
"He's better than I thought," Melvin said, "It's not so much the swelling as it is the soreness in the joint."
In five games after Cespedes won his second consecutive Home Run Derby over the All-Star break, he is batting .381 (8-for-21) with two doubles, two home runs, five RBI and six runs scored.
Callaspo on his way
Alberto Callaspo, rehabbing from a strained hamstring suffered against Seattle before the break, will play baseball this Saturday. Where he will play is yet to be determined, but it will likely be as close to Arlington, Texas as possible. The plan is to have him ready to join the A's for Sunday's game against the Rangers.
"Full go, hopefully, on Sunday," Melvin said. "I'm probably getting ahead of myself, but that's the plan."
Melvin, citing Callaspo's "low maintenance swing," said it's all about his running ability.
The 31-year-old nine-year veteran was hitting .234 with three home runs and 31 RBI in 83 games with the A's this year.
Rest for the 'pen
Melvin said he expects "a few guys" to be unavailable after the A's bullpen worked 8 1/3 innings over the first two games of the Houston series.
Sean Doolittle, Luke Gregerson, Dan Otero and Ryan Cook have all appeared in both games.
Getting a fresh arm in Evan Scribner, who was recalled to fill the space vacated by Jim Johnson, will help.

"He's a part of this team," Melvin said of Scribner. "We're always keeping an eye on him."
Scribner, 29, is 4-1 with a 3.35 ERA in 31 Triple-A appearances this year, collecting 14 saves along the way.
Josh Reddick was productive in his first start since being activated from the DL, with a double, a single, a walk and three runs in the A's 9-7 win over the Astros.

"He looks balanced at the plate," Melvin said. "No issues. He's not thinking about his knee, and hopefully that continues."
