KISSIMMEE, Fla. (AP) – Roger Clemens arrived at the Houston Astros’ minor league clubhouse on Tuesday and walked straight to a fenced-in bullpen to greet his oldest son, Koby, a catcher in the Astros’ system.He snapped at a photographer who started clicking pictures.

“This isn’t a zoo!” Clemens barked.The seven-time Cy Young Award winner was calmer a few minutes later, but refused to answer questions about the Mitchell Report or a possible criminal investigation into his denials of steroid use.

“Everything’s been said that needs to be said on that,” Clemens said. “We’re moving forward. It’s baseball time.”

Clemens will pitch batting practice from Wednesday through Friday to minor leaguers. He arrived one day after The New York Times reported a House committee had drafted a letter asking the Justice Department to look into whether Clemens committed perjury.

Clemens has repeatedly denied that he used steroids or performance-enhancing drugs, allegations brought by former personal trainer Brian McNamee.
