WASHINGTON -- After using five relief pitchers on Saturday, Ron Gardenhire believes he has enough to cover 18 innings of baseball on Sunday.

At least, he hopes so.

"None of them threw too much today," the Twins' manager said after Minnesota's 4-3, 11-inning victory, a win that had Gardenhire concerned about tomorrow's workload. "But I'll have to see how we're doing."

He's right about the workload, especially since the team had Friday off and will have Monday as well. Josh Roenicke threw 20 pitches in his inning of work, but that's the most of any reliever. Glen Perkins threw 17, Jared Burton and Casey Fien 11 apiece, and Brian Duensing just nine.

Baseball rules allow the Twins to add a 26th player to the roster tomorrow, but they called up Chris Colabello, an infielder, for that spot. "It would be tough to make a change, to get someone in here," Gardenhire said. "But we'll see."

Kevin Correia said his seven strikeouts were an indication that he's getting stronger, and he expects his total to keep going up -- "hopefully get a few more than the one or two I was getting" in April, he said.

Correia said he was focused in spring training on getting to the point where he could throw 100 pitches, but "you just naturally get to the point where you can do it and stay strong," he said.

At 3.7 strikeouts per nine innings so far this year, Correia is well below his career average of 5.9, although he spent his first 10 seasons in the National League, where facing pitchers make it easier to rack up strikeouts.
