\New Phillies pitcher Roy Halladay puts on a hat during a news conference in Philadelphia Wednesday. Halliday was traded to the Phillies in part of a four-team trade that sent Cliff Lee to the Seattle Mariners.

PHILADELPHIA — Roy Halladay heard so many rumors last season he was being traded to Philadelphia, he couldn't help but imagine standing on the mound in red pinstripes when they played in the World Series.

"I can't lie," he said. "I did. I had quite a few dreams about it, too."

Halladay has a few more years to make it a reality now that he got his wish and was traded to the Phillies.

Philadelphia sent 2008 AL Cy Young winner Cliff Lee to Seattle Wednesday and acquired 2003 AL winner Halladay from Toronto as part of a complicated, four-team deal, marking the first time in history that two Cy Young winners were dealt on the same day.

"The biggest thing is having a chance to win and hopefully do it a couple of times," Halladay said at Citizens Bank Park. "For me, that was the biggest factor."

All it took was four teams, $60 million and a Cy Young swap to finish off Halladay's long and winding trade saga.

Oakland also was included in the nine-player swap, Money was a key factor, too. The Blue Jays sent $6 million to Philadelphia with Halladay, who then agreed to a $60 million, three-year contract extension through 2013.

"He is a pitcher we have coveted for a long time," Phillies general manager Ruben Amaro Jr. said.

Halladay has never pitched in the postseason in his 12-year career with the Blue Jays. He wanted the chance to play for the 2008 World Series champs.

Toronto sent the 32-year-old Halladay to Phillies for three minor leaguers: catcher Travis d'Arnaud, right-hander Kyle Drabek and outfielder Michael Taylor. The Blue Jays flipped Taylor to the Athletics for third baseman Brett Wallace.

The Phillies dealt Lee to Seattle for three prospects: right-hander Phillippe Aumont, outfielder Tyson Gillies and right-hander Juan Ramirez.
