HOUSTON — At a time when they should have been enjoying the fruits of a 9-3 victory over the Houston Astros and a three-game sweep at Minute Maid Park, the A's were more than a little on edge Sunday afternoon.

First, they had to send right fielder Josh Reddick for X-rays after he smashed his right hand against the right-field wall in foul territory while trying to make a diving catch. A little later, starting pitcher Brett Anderson made the same trip to have X-rays taken on his left thumb and wrist.

Fortunately for the A's, both sets of X-rays came back negative.

The word on Reddick returned first. The right fielder "was scared it could be really serious," but his wrist isn't broken. He probably will have to miss a little time while the sprain heals.

"I've always been taught to dive for balls like that," Reddick said, explaining why he didn't back off with the A's leading 8-0 in the fifth inning. "But I was scared, because I started to lose feeling in the hand."

Reddick said he put out his hand to brace for impact with the wall, which is covered by wire. The result wasn't pretty, and trainer Nick Paparesta and manager Bob Melvin came sprinting from the dugout.

"I'm sorry to have made them run so far so fast," Reddick said. "Bob gets out there quick."

Anderson was hit in the thumb in the second inning by Carlos Corporan's hard chopper up the middle, which went for a hit. After being checked out and saying he was good to go, Anderson lasted until the sixth inning.

That's when he was hit a second time, this time on his left wrist by J.D. Martinez's single. Anderson finished the inning, allowing two unearned runs, but he was done for the day after matching his personal best with 10 strikeouts.

"I reached for the first one, then was trying to pull my hand back out of the way," Anderson said. "It caught me on the thumb. The second one I was trying to get out of the way but didn't."

While he was explaining what had happened, Anderson went from sitting to standing, along the way ramming the back of his head into an open cupboard door above his locker.

"Other than getting hit (on the hand) twice and on the head," Anderson said, "it was a pretty good day."

That it was. Jed Lowrie had three hits, including his third home run, a two-run shot in the third. Coco Crisp had a double and a homer. Chris Young hit a three-run homer. Seth Smith started the scoring with a two-run double as the A's completed the sweep and stretched their winning streak to five games.

"We hit, we pitched well, and we played defense," Lowrie said. "It was a good series for us."

It was particularly good for Lowrie, who at this time a year ago was the Astros' starting shortstop. He finished the series with seven hits, including back-to-back three-hit games, and homered twice. And it was good for Crisp, who homered in all three games and who has five doubles and three homers in his first seven games.

Not that he is going to keep up his pace, but if he did, that would be 185 extra-base hits for the season, a feat that would put him in a new tax bracket.

  • Yoenis Cespedes was supposed to get the day off, but he played the second half of the game after Reddick was injured.

  • During the series, Reddick also got gashes on his right knee and the inner portion of his right elbow.

    "It wasn't a good series for my right side," he said.

  • Infielders Hiro Nakajima and Adam Rosales continue to do rehab work in the Bay Area and are likely to be there when the A's return home Friday after three games in Anaheim.

  • Right-handed pitcher Danny Ortero cleared waivers and will join Triple-A Sacramento. Oakland claimed him from the Yankees on March 29 but designated him for assignment on Friday when they needed space on the roster.
