David Waldstein of the New York Times explains:
[Russell] Martin, a Canadian citizen, told Greg Hamilton, the Baseball Canada head coach and director of the national teams, that he wants to play shortstop in the W.B.C. Hamilton was receptive to the idea.
Canada has two major league catchers on its current roster, including Martin and Oakland’s George Kottaras, who is from Scarborough, Ontario. But it does not have a major league shortstop.
Martin played shortstop in high school and college, and has logged 75 1/3 career major league innings at third base. It might not be the prettiest thing to watch, but the 29-year-old can probably pull it off.
“If it’s something that would help the team, I am willing to do it,” Martin told the Times on Saturday in a telephone interview from Montreal, Quebec. “I told Greg I want to do it, and he said he’s open to it.”
Martin is still an MLB free agent but has drawn interest recently from several teams. The Mariners, Rangers and Red Sox have been linked to him, and the Yankees should be ready to make some sort of offer soon.
