It sucks for the AL, but he's got my support. Sometimes you forget these players have lives outside of baseball, and the lengthy season can get in the way of key moments in a person's life, like the birth of a child or an illness. In Pedroia's case, both are at play.
Luckily for the Red Sox, they have 2 days off after the All Star game which will give him extra days to be with his wife.
He put out this release:
"I have a tremendous amount of respect for the game of baseball and for the All-Star Game and am incredibly honored that the fans voted me this year’s starting second baseman for the American League. I am disappointed that I will not be able to enjoy the amazing experience with the other All-Stars, especially with my Red Sox teammates, but it is important that I put my family first at this time."
Joe Maddon picked up his first baseman Carlos Pena in Pedroia's place. Does that mean Aaron Hill and Ben Zobrist will split duties at second base for the entire game? Not sure why another second baseman wasn't chosen--doesn't make a whole lot of sense, but Maddon seems to be rewarding his own guys.
