De Vries excited for Thursday's debut

CHICAGO -- Cole De Vries got the news he had been waiting for his entire life on Monday.

The hard part? The right-hander couldn't tell anyone.

De Vries, a Minnesota native, was at Triple-A Rochester when manager Gene Glynn told him he was going to be promoted to the Majors the next day. Glynn also told De Vries he couldn't tell his teammates until after the game.

"So I'm sitting there just about having a heart attack because I'm so excited and he tells me that. I'm like, 'What? What am I supposed to do?'" De Vries said Tuesday at U.S. Cellular Field. "He's like, 'I don't care, you just have to sit here for a few minutes, calm down and go back out there and try to go through everything like it's normal.'"

De Vries was finally able to tell his teammates, friends and family Monday night and joined the Twins on Tuesday afternoon in Chicago, where they were set to begin a three-game series against the White Sox. De Vries, 27, will make his Major League debut in Thursday's series finale.

De Vries was 1-4 with a 4.24 ERA, allowing 47 hits with seven walks and 37 strikeouts in eight starts for Rochester and said he's ironed out a few small mechanical adjustments after his first couple of outings.

It's been a long road for De Vries, a 2003 graduate of Eden Prairie High School who pitched at the University of Minnesota before being signed by the Twins as a non-drafted free agent in August 2006. On Thursday, he'll make his Major League debut in front of a group of about 10 family and friends who plan to arrive in Chicago on Wednesday evening.

"I just can't say enough about how great this moment is for myself," De Vries said. "Just with all the hard work I've put in, this being my sixth year of pro ball and finally getting my opportunity is unbelievable. It really is."

Young arms to get a shot to fill holes

CHICAGO -- Twins manager Ron Gardenhire announced his upcoming rotation Tuesday, saying right-hander Cole De Vries will make his Major League debut Thursday against the White Sox with right-hander Anthony Swarzak pitching Friday's series opener against the Tigers.

Right-hander Carl Pavano, who has been dealing with a strain in the front of his throwing shoulder, will start Saturday in Minnesota, giving the righty two extra days of rest.

With Nick Blackburn on the disabled list with a left quad strain, Francisco Liriano in the bullpen and left-hander Jason Marquis designated for assignment Tuesday, Pavano now is the only starter remaining from Minnesota's Opening Day rotation.

Because of the various injuries and overall lack of execution, Gardenhire said he's willing to give youngsters like De Vries, Swarzak and right-hander P.J. Walters, Tuesday's starter, a shot in the rotation.

"We've had some injuries that hurt us out of the spring, but other guys have been scuffling, so you try to make adjustments as best as you possibly can," Gardenhire said. "Just have to ad lib and hopefully we'll have enough depth. Some guys have stepped up and thrown the ball well. It's not what you plan, that's the game. It doesn't always work out that way. You have to be able to ad lib and adjust a little bit and that's what we're trying to do."

Doumit returns to lineup as designated hitter

CHICAGO -- Ryan Doumit returned to the Twins' starting lineup for the first time since May 16 on Tuesday against the White Sox, batting sixth as the designated hitter.

Doumit, who has been dealing with a strained right calf, pinch-hit Saturday in Milwaukee but was lifted for a pinch-runner after drawing a walk.

Twins manager Ron Gardenhire said Doumit felt great and even caught a bullpen session earlier in the day, but Gardenhire cautioned him to take it easy on the basepaths.

"Let's get by the first few days here and see how his calf reacts to that," Gardenhire said. "But he feels good and it's nice to see him back in there."
