Former major league catcher Mike Matheny says the hit that knocked out San Francisco's Buster Posey for the rest of the season could have easily been avoided. Matheny's career was ended by concussions. "You know what, it wasn't a dirty play, he didn't come high spikes, he didn't come high elbow," Matheny said. "But it wasn't a necessary play. He was hunting. Buster gave him an option and he didn't take it." Matheny, 40, finished his career with San Francisco in 2007 and is a minor league instructor with St. Louis. Florida's Scott Cousins went out of his way to take out Posey in a play at the plate last week.
