In one of the most significant gambles in recent franchise history, the Mets traded National League Cy Young Award winner R.A. Dickey to the Blue Jays in a seven-player deal on Monday.

The Mets reached agreement Sunday on a trade of Dickey, and he and the Jays quickly negotiated a three-year, $29 million contract that will keep Dickey in Toronto through his age-40 season.

The deal also sent catchers Josh Thole and Mike Nickeas to Toronto for catchers Travis d'Arnaud and John Buck, pitching prospect Noah Syndergaard and Minor Leaguer Wuilmer Becerra.

Dickey is the seventh Cy Young Award winner to open the following season with a new team and the fourth to leave via trade. The most recent example came more than a decade ago, when the Jays shipped Roger Clemens to the Yankees prior to the 1999 season.

"It's a huge decision," manager Terry Collins said earlier this month. "There's a lot of things to consider -- your fan base, the team. But if you do something like that, it's for the benefit of the organization in the long term."

The Mets have now parted ways with the NL's reigning batting champion and Cy Young Award winner in consecutive offseasons. For the former, Jose Reyes, they received two Draft picks. For the latter, they are about to receive a significant haul of impact players.

D'Arnaud, 23, has long ranked among the top young talents in baseball, clocking in at No. 11 on's 2012 Prospect Watch. He is used to this sort of deal; the Jays acquired him from the Phillies in 2009 for another Cy Young Award winner, Roy Halladay. Batting .333 with 16 homers in 67 games at Triple-A Las Vegas, d'Arnaud might have made his Major League debut already had he not torn a left knee ligament in June, ending his season.

To replace Thole, the Mets acquired Buck, 32, who has seen his production tail off significantly since bashing a career-high 20 homers with the Jays in 2010. He played last season with the Marlins, but returned to Toronto in the trade that sent Reyes north of the border.

Syndergaard, 20, posted a 2.60 ERA with 122 strikeouts and 31 walks in 103 2/3 innings last season at Class A Lansing. The Jays' third-ranked player on's Prospect Watch, he figures to slot into the Mets' rotation at high Class A St. Lucie, putting him on track for a big league debut in late 2014 or early '15. He profiles as a mid- to top-of-the-rotation starter.
