Giants catcher Buster Posey says it's "highly likely" he will miss the rest of the season after injuring his left leg and ankle in a collision at home plate. Posey said in a conference call that he is still committed to playing catcher when he returns. He also asked that Major League Baseball and the players' union look at ways to protect catchers at home plate. Posey is in the process of seeking a specialist to perform surgery on his ankle. He said he's in almost constant pain but confident he will make a full recovery, even if it's unclear exactly how long that will take. "I think we'll know more once we do some surgery," Posey said. "I think it's highly likely I probably won't be back (this season), from what I'm hearing."
