MINNEAPOLIS -- Matt Capps said he felt good in his first appearance since returning from the disabled list despite some jitters.

Capps threw a scoreless eighth inning with one strikeout against Oakland on Saturday. He was activated from the DL on Friday after missing 15 games with right shoulder inflammation.

"A little bit of jitters that first time back out there, but I felt pretty good," he said. "It was nice to get that first one under the belt. Breaking ball and offspeed stuff felt pretty good and I was down with the fastball. All in all, for the first time back out there in three weeks, I felt pretty good out there."

The right-hander converted 14 of 15 save opportunities before the injury. Minnesota may ease him into another appearance with less pressure before using him as closer again.

"Obviously, the competitive side in me wants to get right back onto the saddle," Capps said. "But I'll take getting out there any time I can."

De Vries not worrying about future with team

MINNEAPOLIS -- Cole De Vries doesn't know how long his current stint on the Twins' big league roster will last, but he's trying not to worry about it.

The rookie right-hander is currently in his third stint with the club this year. His seventh outing of the season on Saturday was also his worst as Oakland battered him for a season-worst seven runs, five of which came from three home runs.

"I really try to not put anything into [how long I'll be here] because then it's going to put so much added pressure on myself," he said. "I think it's very hard to pitch when you put more pressure on than there should be."

Still, unlike his second stint -- which saw him allow only one run in six innings against the Royals in his only start -- De Vries will have at least one more start this time to make another impression as he's slated to get the ball on Wednesday against Baltimore.

De Vries is 2-2 with a 4.37 ERA, though he entered Saturday's game with a 3.00 ERA. His previous start, conversely, was his best. He threw seven shutout innings against the Rangers on July 8.

"I've had a few good outings -- my last ones," he said. "This is just one of those outings that wasn't very good. We all have them. That's why I'm going to try to make my next one as good as I can."

Dozier working through rookie-season struggles

MINNEAPOLIS -- Brian Dozier has made his share of nice plays for the Twins at shortstop, but his rookie season hasn't been without growing pains.

Offensively, Dozier's .303 average this month entering Sunday's game tops his .228 and .231 marks in May and June. Defense has seemingly come more slowly for the 2011 Twins Minor League Player of the Year. Dozier's 13 errors entered Sunday tied for the second-most among Major League shortstops.

Manager Ron Gardenhire said the staff continues to work with Dozier on not playing so deep in the hole at short.

"He's had his moments where he's OK," Gardenhire said. "I still think he gets sloppy with his glove a little too much. He makes plays a lot harder than they should be. He plays really deep. We've had conversations about shortening it up -- you have to make adjustments on these infields."

Even though Dozier's bat has been steady as a rookie shortstop, Gardenhire is also looking for situational improvements.

"Situations like putting hit and runs on, even though the pitch might be off the plate, you as the hitter have to find a way to put the bat on the ball," Gardenhire said. "You can't leave a runner out there. Those are situations that he's built for -- hit and runs and things like that. And he's got to get better at that."
