KISSIMMEE, Fla. — Roger Clemens might show up at Houston Astros spring training this week for a minor league minicamp that includes his son, Koby.

The minicamp begins tomorrow in Kissimmee and Koby Clemens, a catcher in the Astros' minor league system, is expected to participate. Minor leaguers could check in for the camp today, but neither Koby nor his father arrived before the minor league clubhouse closed at 5 p.m.

Roger Clemens has come to the spring camp with his son the past few seasons. He has a personal services contract with the Astros that will kick in when he officially retires.

Houston manager Cecil Cooper said he was expecting the seven-time Cy Young Award winner to attend the camp, but said he didn't know when he might arrive. Neither general manager Ed Wade nor assistant GM Ricky Bennett had any indication when Clemens would arrive or if he'd show up at all.

"I really don't know Roger's situation," Wade said.

Clemens threw batting practice at the Astros' weeklong minicamp in Houston that preceded spring training. Two weeks later, on Feb. 13, he testified before the House Committee on Oversight and Government Reform and again denied allegations by former trainer Brian McNamee that he used steroids or human growth hormone.
