The New York Yankees acquired pitcher Shawn Chacon from the Colorado Rockies for a pair of minor-leaguers on Thursday night, filling the opening in their injury-ravaged rotation. In exchange for Chacon, a 27-year-old right-hander, the Rockies get Ramon Ramirez and Edwardo Sierra. "Saturday we have a starter now. It's as simple as that," Yankees general manager Brian Cashman said. "Our team is working hard on the field. We're working hard in the front office to be in a position to improve the club. It seems like we've been plugging holes on the run the last few weeks at an unusual pace." Chacon was an All-Star for the Rockies in 2003, when he had 11 wins at the All-Star break. But he didn't get another victory and finished 11-8 with a 4.60 ERA. Colorado moved him to the bullpen the following year and while he had 35 saves, he also had nine blown saves to go along with a 1-9 record and a 7.11 ERA. He is 1-7 with a 4.09 ERA this year in 12 starts and one relief appearance. "I pitched one inning in Yankee Stadium last year and it was an unbelievable experience as a visitor," Chacon said at Coors Field in Denver. "I can only imagine what it's like to have that as your home park. The atmosphere there is a little different from here. That brings up everybody's level of play. All that history, the electricity in the crowd, and I think everybody there tries to live up to that. You put on that uniform and it is all about winning."
