McNamee testifies before a grand jury

Roger Clemens's former personal trainer, Brian McNamee, was questioned for five hours yesterday by federal prosecutors and investigators building a perjury case against the seven-time Cy Young Award winner.

McNamee did not speak to reporters, only shaking his head when asked if he would comment, when he arrived in the morning at the US Attorney's office in Washington accompanied by his lawyers, Richard Emery and Earl Ward.

McNamee has told federal agents, baseball investigator George Mitchell, and a House of Representatives committee that he injected Clemens more than a dozen times with steroids and human growth hormone from 1998-2001. This, however, was McNamee's first meeting with Assistant US Attorney Daniel Butler, who is presenting evidence to the federal grand jury determining whether Clemens should be indicted on charges of lying to Congress when he denied using performance-enhancing drugs.

Emery would not say what was discussed and declined a request to interview McNamee.

The New York Yankees and Mets won their fight to get public backing for additional financing for their new ballparks that will save them hundreds of millions of dollars in interest payments.

The city's Industrial Development Agency approved additional public bond requests for the teams, which were given hundreds of millions in tax-exempt bonds when construction began in 2006.

The Yankees were granted another $259 million in tax-exempt bonds and $111 million in taxable bonds, on top of $940 million in tax-exempt bonds and $25 million in taxable bonds already granted for the $1.5 billion new Yankee Stadium in the Bronx.

The Mets got an additional $83 million, after the $615 million already approved for $800 million Citi Field.

Christopher De La Rosa, a 19-year-old outfielder in the Red Sox system, has received a 50-game suspension for testing positive for a performance-enhancing substance. Major League Baseball announced the suspension yesterday, along with the suspension of Mets Triple A pitcher Junior Guerra. De La Rosa, who was on the Sox' Dominican Summer League team, tested positive for metabolites of stanozolol.

De La Rosa signed with the Sox in 2007 and was not a significant prospect. He struggled last season, hitting .219 with one home run and 16 RBIs in 42 games, and was going to spend next season in the DSL.
