HOUSTON -- A's lefty Brett Anderson took his rehab to a pitching mound in Houston on Monday, throwing a 35-pitch bullpen without any issues.
Anderson, missing from the rotation since April because of a stress fracture in his right foot, utilized all his pitches in the session with manager Bob Melvin looking on, and he continues to aim for an August return.
"It looked like there were no problems with his arm," Melvin said. "He threw the ball really well. You could tell he was excited to be out there, and [he] didn't have any issues with his foot."
Anderson, 25, will throw again on Wednesday, as he continually builds back arm strength. Not much of his strength was ever lost, though, since Anderson threw from one knee after suffering the injury.
"It was kind of depressing throwing on one knee, but that was probably the best thing I could've done to keep up the arm strength," he said. "That helped quite a bit, because I feel I didn't really lose any [strength].
"Today was good. Obviously a little different throwing off the mound than flat ground, so throwing some pitches took a little getting used to. But I'm happy about it. It's kind of like riding a bike."
Cespedes again sits, remains day to day
HOUSTON -- As expected, Yoenis Cespedes remained out of the A's lineup on Monday, and his chances of playing on Tuesday appear slim since he's yet to even take batting practice.
Manager Bob Melvin said the plan is for the left fielder, who is dealing with a sore left wrist, to take batting practice on Tuesday, making a Wednesday or Thursday return more likely.
But Melvin didn't rule out the possibility of Cespedes playing on Tuesday.
"If everything goes well, and he doesn't feel any soreness, he'll take batting practice tomorrow," Melvin said. "He did everything in the cage today, from soft toss to tee work, everything but live hitting, and felt good."
Cespedes has missed each of Oakland's four games since the All-Star break.
• In the wake of Monday's announcement that Brewers outfielder Ryan Braun has been suspended without pay for the remainder of the season after coming clean about violating the game's Joint Drug Prevention and Treatment Program, Melvin was asked whether he was concerned about the possibility of losing Bartolo Colon -- who, like Braun, has been connected to the Biogenesis clinic -- to a suspension.
Melvin said he remains "consistent with the stance that I've had all along," believing Colon, who served a 50-game suspension after testing positive for an elevated level of synthetic testosterone last year, has already paid his dues.
• Houston native Chris Young, batting second on Monday, entered the game as a career .339 hitter against the Astros, with 11 home runs and 45 RBIs in 44 games.
Young had done particularly well near his home confines, batting .404 with seven home runs in 21 games at Minute Maid Park.
He burnished those stats in Monday's 4-3 win, going 2-for-5 with a triple and his ninth homer of the year, a solo shot in the seventh off lefty reliever Travis Blackley, a former member of the A's.
"He does have some history here," Melvin said, smiling, before the game. "I'm sure the Chris Young fan club and family pack with be here in full force, as they always are here."
