Donald recovering slowly from wrist ailment

KANSAS CITY -- Injured Cleveland infielder Jason Donald is not recovering from his wrist injury in rapid fashion.

Donald was hit in the right wrist with a pitch on Sept. 14 against Detroit, and he hasn't appeared in a game since.

"It's slow progress," Indians manager Manny Acta said. "He's going to swing the bat [Sunday], going to feel for it. But that thing got him pretty good. He was going through some numbness there. It was an issue to swing the bat and throw the ball 100 percent."

Acta wants to see better batting eye from Carrera

KANSAS CITY -- Indians outfielder Ezequiel Carrera has played pretty much every day since his promotion on Aug. 3. And, while manager Manny Acta said he's seen some improvement, he needs to see more.

"Carrera has come up this year, his swing is a little bit better, more consistent. But he still needs to continue in his control of the strike zone," Acta said. "His walk-to-strikeout ratio's not good. It's not just necessarily about walking. It's about controlling the strike zone so you can handle better pitches and get a higher on-base percentage. His game depends so much on being on base because of his velocity. He's made some improvement over last year, but he still needs to show more."

In his 42 games this season, Carrera has walked just six times compared to 33 strikeouts. He's hitting .242 with a pair of home runs and seven RBIs. He appeared in 68 games for the Tribe last season, batting .243, but his on-base percentage was .020 points higher (.301) than it is this season (.281).

When it comes to evaluating all his midseason call-ups, Acta said, the proof is in the numbers.

"You need to perform. That's the bottom line," Acta said. "This is not scouting school. I'm not sitting here evaluating how fast a guy is or anything like that. It's about performing. We've given guys opportunities. Some others haven't gotten as much of an opportunity that we'd like to. And you can look at the numbers. That's what this game is all about."

Quote to note

"I think he deserves a lot of credit for doing that. I think he scored a lot of points when it comes to character by doing that. I don't know how many people would do that. I respect him a lot more after that decision." -- Manager Manny Acta on Giants outfielder Melky Cabrera's request to be eliminated from contention for the National League batting title.

Smoke signals

• Travis Hafner's next home run will be his 200th as a member of the Indians. He hit one homer in his only season outside of Cleveland, 2007, with the Rangers.

• The last seven Cleveland wins have all come by one run, and the Indians are 22-10 in one-run games this season.
