Beyond the baseball card: Ryan Dempster

The Red Sox introduce their newest starting pitcher on Wednesday, with Ryan Dempster meeting the Boston media. The 35-year-old has been a starter, a closer, then a starter again during a career that's now taken him to five big-league cities, so certainly with that breadth of experience there's a lot to know about him.

Notably, the Canadian pal of Kevin Millar was named by The Sporting News as one of the "99 Good Guys in Sports" back in 2001, and now one of his primary focuses is the Dempster Family Foundation, which is dedicated to raising awareness of 22q11.2 deletion (DiGeorge Syndrome/VCFS) and reaching out to families with children with the disorder, and the charities that support them. It's a cause near and dear to Dempster, whose infant daughter, Riley, was diagnosed with the syndrome back in 2009, and whose foundation is actively taking donations in creative denominations.

But aside from being an inning-eating hurler, Dempster may best be known for his spot-on impersonations. In Chicago, especially, his Harry Caray was a hit, though he does a darn good Matt Foley -- yes, the motivational speaker -- as well. Check out the clips below, and if you're thirsty for more laughs, there's plenty on YouTube. (And something tell us that by the end of his new deal, there'll be a Joe Castiglione imitation to add to the collection.)
