Tonight in Phoenix, Major League Baseball’s hardest hitters will battle it out to see who’s got the biggest bat of them all. The sport’s biggest stars will not only be swinging for the fences but interacting with fans via Twitter during the 2011 Home Run Derby. Get ready to ask the players questions, find out what’s on their minds, and maybe enjoy a little trash talk while watching the derby live. What’s next, players tweeting from the outfield of the World Series?

Here is a list of the players Twitter accounts thanks to Mashable.com:

American League captain David Ortiz (@davidortiz), Jose Bautista (@JoeyBats19) and Kemp (@TheRealMattKemp) will be tweeting on their accounts during the course of the event as participants, and so will other All-Stars including Heath Bell (@HeathBell21), Gio Gonzalez (@GioGonzalez47), Hunter Pence (@HunterPence9), Brandon Phillips (@DatDudeBP), Gaby Sanchez (@GabySanchez215), Justin Upton (@RealJustinUpton), Major League Baseball’s first Tweeter C.J. Wilson (@str8edgeracer), Howie Kendrick (@HKendrick47) and Joel Hanrahan (@hanrahan4457).

Whether there are computers in the dugout or Smartphone’s in their pockets I don’t know; but fans of the game and tweeters are guaranteed to have a blast. Grip it and Rip it!
