NEW YORK (AP) _ Five-time Cy Young Award winner Roger Clemens was traded by the Toronto Blue Jays to the New York Yankees today for David Wells, Graeme Lloyd and Homer Bush, a source familiar with the talks told The Associated Press.

Clemens agreed to the deal, but did not get an extension to his contract, which has two years to run and calls for him to be paid $16.1 million.

The deal will be announced later today, the source said, speaking on the condition he not be identified.

The deal shakes up the World Series champions on the day they start training camp. Wells, a quirky left-hander, was the toast of New York after pitching a perfect game against the Minnesota Twins last season.

While he clashed with owner George Steinbrenner and manager Joe Torre at times in 1997, he reached a tentative peace with them last year and became one of the team's most effective pitchers.

Clemens, coming off consecutive Cy Young awards, exercised a clause in a side agreement between himself and the Blue Jays, demanded a trade on Nov. 27, then withdrew the demand Dec. 22, criticizing Houston Astros general manager Gerry Hunsicker for blasting his request for a $27.4 million, one-year contract extension, which would have left the Astros owing him $43.5 million over three years.

Texas, Cleveland and Houston also expressed interest in the 36-year-old right-hander, who went 20-6 last season, leading the American League in ERA (2.65) and strikeouts (271), and tying for the lead in wins. His career record is 233-124 in 15 seasons.
