Saturday' s tennis was memorable for one thing the weather wrought. That was the shriek of jet engines over Queens which other than the lack of a green court and quick camera views of Mayor Dinkins reminded us of how far the US Open has come. Federer is vulnerable but Nolo offered only passable resistance. In the booth during Federer's quarter final, Boris Becker and John McEnroe conversed in some of the best tennis analytics I have ever heard. Discussing how Federer is less confident, is playing several feet back from the base line and far less confident he can overwhelm his opponents. Far better discussion than the tedious repetition about about Uncle Tony, rankings, and Andy Murray's muscles.
