The plot thickens

From the AP:

Andy Pettitte used human growth hormone to recover from an elbow injury in 2002, the New York Yankees pitcher admitted two days after he was cited in the Mitchell report.

Pettitte said he tried HGH on two occasions, stressing he did it to heal faster and not enhance his performance. He emphasized he never used steroids.

"If what I did was an error in judgment on my part, I apologize," Pettitte said Saturday in a statement released by his agent. "I accept responsibility for those two days."..

Hmmm. Roger, any thing to add?
