OAKLAND -- Though health appears to be back on his side, A's shortstop Cliff Pennington will have to watch his club engage in three pivotal games with the Angels from afar with Triple-A Sacramento.

It's there where Pennington will continue a rehab stint this week, despite going a combined 3-for-7 with two walks and a stolen base in two starts at shortstop for the River Cats over the weekend.

"He'll probably play there the next three days, and then we'll see where we're at with him," manager Bob Melvin said Monday.

Melvin noted over the weekend that he'd like to bring back Pennington at a time when he's swinging well, given his season-long struggles. At the time of his left elbow injury, he was batting just .197 with a .259 on-base percentage.

In his stead recently, Eric Sogard and Adam Rosales have been sharing time at shortstop, going a combined 9-for-41 (.220). It's unknown whether Pennington will join the A's for their six-game road swing through Chicago and Kansas City beginning Thursday, though Melvin said, "I think anything's a possibility."

Cespedes out of starting lineup with wrist ailment

OAKLAND -- For the start of a three-game set against one of the league's best pitching staffs, Oakland was without its most feared hitter on Monday.

Yoenis Cespedes, still battling right wrist soreness, was held out of the A's lineup for their evening matchup with Angels righty Jered Weaver, owner of a career 2.63 ERA vs. Oakland.

After injuring the wrist when sliding into third base in the sixth inning of Friday's 15-inning affair vs. Toronto, Cespedes appeared in Saturday's game only as a pinch-runner. Upon Cespedes' return to the starting lineup Sunday, manager Bob Melvin said the wrist "bothered him a little bit."

"Especially the last couple of at-bats," Melvin said. "So we're going to try to give him a full day off today, not swinging in batting practice, and hopefully he'll feel that much better tomorrow."

Cespedes, who has battled numerous injuries in his first big league season, is batting .410 with five home runs and 18 RBIs in 21 games since the All-Star break. The A's are 46-29 with him in the starting lineup and 12-21 when he doesn't start.

Worth noting

• A's lefty Brett Anderson made his fourth rehab start on Sunday, giving up three runs on five hits, including one home run, with two walks and three strikeouts in 4 1/3 innings of work for Triple-A Sacramento. Anderson threw 70 pitches and is expected to increase that total to 90 in his next start with the River Cats. The team would like to see him throw 100 before deeming him ready to return to the A's rotation.

"Health is key with him, and he felt good after yesterday's outing," Melvin said.

Anderson has been out since last season following Tommy John surgery.

• Outfielder Seth Smith, placed on the 15-day disabled list Friday with a strained left hamstring, has yet to resume baseball activities.
