BOSTON -- Chris Sale said he isnt worried that he might not be the ace of the Boston pitching staff after being added to a Red Sox rotation that already includes David Price and reigning AL Cy Young winner Rick Porcello.We play for a trophy, not a tag, Sale said on a conference call Wednesday, a day after the AL East champions acquired him from the Chicago White Sox for a package of four minor leaguers that includes No. 1 prospect Yoan Moncada. It takes some pressure off of everybody. Just go out there and pitch, because you dont feel like you have this huge weight on your shoulders to win this game.A five-time All-Star who finished in the top six of the Cy Young voting the last five years, Sale was traded to Boston on Tuesday at the winter meetings for four prospects -- including Moncada, who was Baseball Americas minor leaguer of the year this season.

Asked before the official start of winter who his opening day starter will be, manager John Farrell said, Well have plenty of time to figure that out.Theres a surplus right now, he said on Tuesday. But when you think about the high end of it, this is an exciting group.Sale was 17-10 with a 3.34 ERA and 233 strikeouts this season, one year after his 274 strikeouts led the majors. He is scheduled to make $12 million next year, with club options that could keep him in Boston for two more years at $12.5 million and $15 million.The relatively affordable contact had contenders coveting him since last years trading deadline, and the White Sox knew he was their bes
