It was after midnight, during a sides-change in the fourth set of the quarterfinal U.S. Open epic between Andre

Agassi and James Blake when John McEnroe, working the match on USA Network, said, “Let’s take a quick look

at the match summary.”

A full screen stats graphic appeared. McEnroe paused for half a second, then said, “And we’ve looked at it, now let’s go back to the match.”

“He got me, got me good,” USA’s lead U.S. Open producer, John McGuinness yesterday told The Post. “I try not to stick graphics up there for any old reason, but McEnroe called me out on that one. He caught me.”
