Reigning NL Cy Young winner R.A. Dickey will pitch for Team USA at the World Baseball Classic, according to

The 38-year-old knuckleballer, acquired by the Blue Jays this offseason, will join a U.S. staff that includes San Francisco's Ryan Vogelsong and veteran lefty Andy Pettite, the league website reports.

The U.S. club, which will be managed by ex-Yankees bench boss Joe Torre, has yet to officially announce its roster, though Ryan Braun, David Wright and Joe Mauer have all committed to play.

Canada named 23 players to its provisional roster Saturday, including Jays' third baseman Brett Lawrie, Twins' DH Justin Morneau, Pirates catcher Russell Martin and Brewers' closer John Axford.

Etobicoke's Joey Votto, the 2010 NL MVP, is expected to be added to the roster once he passes an additional physical.

The World Baseball Classic runs March 2-19 with games in multiple countries. Canada, who will compete in Pool D with the U.S., Mexico and Italy, open the tournament against the Italians on March 8 in Phoenix, Az.

In addition to Dickey and Lawrie, other Blue Jays expected to participate in the tournament are Jose Reyes and Edwin Encarnacion, both for the Dominican Republic. Jose Bautista would like to participate, but the Jays are unlikely to grant him leave since he ended last season on the disabled list.
