All wasn't lost for the prosecution in the Roger Clemens perjury trial, despite his former teammate Andy Pettitte saying on Wednesday that he could have misunderstood Clemens when he was told about his human growth hormone use.

Jeff Novitzky, a special agent for the Internal Revenue Service who investigates the distribution of performance enhancement drugs and was part of the BALCO investigation, testified that he received a tip of former Mets clubhouse attendant Kirk Radomski dealing PEDs and executed a search warrant on Radomski's house, which subsequently led to an investigation of McNamee.

Novitzky spoke on meetings he had with McNamee, saying Clemens was one of the people mentioned in the conversations which discussed the trainer's alleged involvement in distribution of PEDs. This, from baseball writer John Schlegel:

Novitzky also related the receipt from Emery of medical waste McNamee says he kept in a beer can that the government contends connects Clemens via DNA evidence to using steroids.

So gross.
