CLEVELAND -- Kerry Wood was activated off the disabled list Friday. He'll be activated in the closer's role Tuesday.

Wood passed the final test of his rehab Sunday against the Tigers, when he made his second appearance in as many days and had no complications involving the back muscle that had landed him on the DL at the outset of the season.

In both appearances, Wood was brought out in the seventh inning, as manager Manny Acta opted to ease him back toward closing duties.

"Today was his last test," Acta said after the Tribe's 7-4 victory. "The move [to closing] will take effect Tuesday in Kansas City."

That means Chris Perez, who finished off his fifth save in seven opportunities Sunday, will move back to a setup role.

Wood, who saved 20 games in 26 opportunities last year, gave up two runs on a Miguel Cabrera single with two outs to break a seventh-inning tie in Saturday's 6-4 loss to the Tigers. He faced Cabrera again Sunday, with none on and two out in the seventh, and got him to pop out. That was the only batter he faced.

"I feel good," Wood said. "It helps that I'm getting better command of my breaking ball. I'm happy with where I'm at."

Valbuena's struggles following him to field

CLEVELAND -- Luis Valbuena was already slumping at the plate, and now he's slumping in the field.

Valbuena had a day off Sunday, and he might have needed it after committing four errors in three games at shortstop last week. With Asdrubal Cabrera back in the Tribe lineup for the series finale against the Tigers, Valbuena was given a day off and Mark Grudzielanek started at second.

Though he said he feels comfortable at short -- a position he started at 22 times last season -- he didn't always look it while filling in for Cabrera. And his struggles in the field only draw more attention to Valbuena in what has been a rough first full season in the big leagues.

"I'm working on things," Valbuena said. "I want to keep working and take it into the game. I'm working on my hitting and my fielding, and I need to put it all together."

Valbuena is batting just .167 (11-for-66) with a .616 OPS this season. He's currently mired in a 3-for-27 funk.

The hot start by Jason Donald at Triple-A Columbus put even more attention on Valbuena in the early going. Donald has cooled a little bit this past week, but he's batting .294 with an .862 OPS on the season, getting the bulk of his time at second base. A Donald callup does not appear imminent, but that doesn't mean veteran Mark Grudzielanek, who had a pair of RBIs in Sunday's 7-4 win over the Tigers, won't start to see more time at second base.

"We could be leaning that way," manager Manny Acta said. "[Grudzielanek] has already been playing more than we anticipated."
