Match Of The Day

Match of the event, really. It's sure to get better down the road, but when Sam Querrey won 94% of all his service points to cruise past Stanislas Wawrinka 6-2 in the first set, I knew Stan would step up. It wasn't that he was playing poorly, after all, but Sam was on fire.

Second set was high-quality from both sides of the net. Sam cracked first, dropping his serve at 5-6 to surrender the set. By late in the third, the atmosphere turned Davis Cup-esque, though the fans were ultra courteous to the Swiss, who was giving them all sorts of reasons to applaud.

The tiebreak began thus: first 8 points, 8 first serves. Players exchanged one mini break. Then Stan double faulted, leaving the match on Sam's racquet at 5-4. Sam made a first serve, but retreated from the net on a forward approach and paid the price. A controversial overule on the sidellne gave Sam his first match point at 6-5. Forcing play brought Stan to match point at 7-6. Sam served back-to-back aces to lead 8-7. Stan had enough. He flashed his gonads and won the last three points of the match at the net.

That's what made all the difference:

Balls.
