A's claim Parrino off waivers from Rangers

OAKLAND -- The A's and Rangers have done a bit of poaching from each other in recent years on the waiver wire.

In the latest move, Oakland claimed infielder Andy Parrino from the Rangers off waivers on Monday, sending him to Triple-A Sacramento and adding him to the 40-man roster. Parrino spent Spring Training in A's camp before being designated for assignment by the club on Feb. 27.

The Rangers picked him up on March 3 but then designated him for assignment on Friday after he batted .189/.271/.245 with no homers and five RBIs for Triple-A Round Rock. Parrino spent the 2013 season in the A's organization and played 14 games with Oakland.

"We do seem to maybe target the same type of players," Melvin said. "I'm not part of the front-office dynamic as far as claiming players and so forth. But a guy that we've had, we did have a 40-man roster spot open and a guy that we know a lot of about, so it made some sense to claim him."

The move is reminiscent of the situation with infielder Adam Rosales last year, who shuttled back and forth between the two AL West foes on the waiver wire.

A's trying to clean up defense

OAKLAND -- The A's entered play on Monday in a three-way tie for the most errors in the Majors this year, their total of 20 only matched by the Dodgers and Nationals.

On Sunday, Oakland committed two defensive miscues for the fourth straight game, and it marked the ninth consecutive contest where the team made at least one an error.

Manager Bob Melvin notices the trend, but sounds tired of discussing the subpar defense at this point.

"Like any hitter that may be is in a slump," Melvin said, "we just need to get a few games back to back together so we're not hearing about it all the time and I'm not addressing it and we're not having to do things that seem like they surround it all day long."

Melvin has also changed up the pregame schedule recently, giving his infielders a head start on the field before batters hit the cage. The infield has accounted for 15 of the team's errors, while outifelders have made three and pitchers and catchers have made two.

"It's a lot easier to take ground balls and so forth when nothing's going on out there," Melvin said.

The slick-fielding Josh Donaldson, who has still turned in a host of a highlight stops this young season, has a team-high five errors in 18 games, including a boot of a routine grounder on Sunday. Still, Melvin doesn't sound too concerned about his talented third baseman.

"These things take on a mind of their own sometimes when that's being written about every day, they're being asked about it every day," Melvin said. "It can. The play he makes the error on yesterday, he makes 499 times out of 500.

Injured Cespedes starts Texas series on bench

OAKLAND -- Slugging A's outfielder Yoenis Cespedes was on the bench to start Monday's series opener against the Rangers, a day after exiting early due to a bruised right heel. Left-handed hitting Brandon Moss made the start against Texas righty Yu Darvish in Cespedes' place, batting fifth.

Cespedes first showed signs of heel discomfort in the A's clubhouse following an April 6 contest against the Mariners, but still played in every inning of the season until leaving Sunday's contest.

"He's gone back and forth with it," manager Bob Melvin said. "Some days it bothers him and some days it doesn't. It hasn't for several days and then it popped up it again, so I think it's best served if we give him a day."

Cespedes has shown signs of wear and tear since beginning his MLB career in 2012, making two trips to the 15-day disabled list and missing 60 games in that span. Melvin said Cespedes' injury affects him especially when he's running, but that the outfielder would be a potential late-game substitution on Monday.

It's just the latest issue for what's been a banged up outfield for Melvin. Craig Gentry (back) started the season on the 15-day disabled list and has been getting more playing time lately now that starting center fielder Coco Crisp has been limited by left wrist issues.
