MLB.com: Prospect punctuates win for Marlins

Even in a relief role, Chris Volstad turned out being the Marlins’ much-needed stopper on Sunday afternoon. Volstad tossed two scoreless innings in his big league debut, and backed by Cody Ross’ five RBIs, the 21-year-old helped the Marlins salvage the series finale with the Rockies, 10-5, in front of 27,167 at Coors Field.

But the big boost came from Volstad, the first-round pick in 2005, who was called up from Double-A Carolina on Sunday morning. Projected to be a starter, he appeared in relief in the fifth and six innings, taking over for Mark Hendrickson, who gave up four runs in four innings.

“I found out last night about 11,” Volstad said of when he got the call. “I flew out [of Raleigh, N.C.] at 6 in the morning. I got here with enough time to play catch and get out to the bullpen.

After the game, Marlins manager Fredi Gonzalez announced that Volstad will move into the rotation, and get his first start on Friday against Los Angeles at Dodger Stadium. Hendrickson, meanwhile, will be moved to the bullpen, where he becomes the second lefty option.
