(July 29, 2012) -- Andy Murray made short work of a very tricky competitor today as heavy rains beat down like a drum circle on Wimbledon’s roof.

Murray’s surprisingly uneventful 6-3, 6-3 victory over Stanislas Wawrinka was his first ever at the Olympic Games, and his first match since his heartbreaking yet endearing loss to Roger Federer in the Wimbledon final.

Murray will next face the winner of the Jarkko Nieminen-Somdev Devvarmen match in the second round.

Against a foe that has troubled him in the past (Wawrinka took Murray to five sets in their last Wimbledon encounter and upset him at the 2010 US Open), Murray broke a first-set stalemate in the eighth game as Wawrinka double faulted to give the Scot a break opportunity. Murray chased down a drop volley to land a backhand down the line to secure the break, then served out the next game without any trouble to snare the first set.

The presence of 17-time Grand Slam champion Roger Federer in his player’s box couldn’t spur Wawrinka to greater heights today, as he was broken again to start the second set, and from there Murray kept his grip on things, saving the only break point he would face in the second set and losing only six points out of 30 on his serve for the set.

With Wawrinka serving to stay alive in the match, the World No. 26 served two double faults from 40-15 to bring things to deuce, then made his final two errors of the day (all totaled, he committed 32) to end things with a murmur in one hour, twenty-nine minutes.

Djokovic, Tsonga Avoid Upset Scares

Both Novak Djokovic and Jo-Wilfried Tsonga found themselves in perilous positions on Sunday after each lost their first set tiebreakers. But both rose to the Olympic challenge to record hard-fought, three-set victories.

In a shaky first set on Court 1 Novak Djokovic missed on multiple set points against Fabio Fognini of Italy (and failed to serve out the set from 5-4), and the two broke for a three-and-a-half hour rain delay while deadlocked at 7-7 in the first-set tiebreaker. When they finally returned to action, Fognini reeled off two quick points, finishing the second with a backhand winner and a fist-pump to take the lead.

But Djokovic displayed his trademark fortitude in sets two and three. He didn't allow the Italian a sniff of a break point the rest of the way, breaking twice in each of the second and third sets to turn the potential shocker into a breezy 6-7(7), 6-2, 6-2 victory.

Tsonga also found himself a set down when he missed a backhand long to hand the explosive Thomaz Bellucci the first set after a tense tiebreaker in which mini-breaks were hard to come by.

But the Frenchman was whistling a different tune in the second and third sets as he found ways to break the Brazilian, and also did a wonderful job of holding serve despite steady pressure from Bellucci. Tsonga had to fight off three break points and hit 17 winners in the final set, and he finally sealed the 6-7 (5), 6-4, 6-4 victory with a diving backhand volley on match point.

Tsonga awaits the winner of the first-round match between Milos Raonic and Tatsuma Ito tomorrow, while Djokovic will play either Andy Roddick or Martin Klizan in the second round.

Rains Wipe Out All But Seven Matches on Sunday

The heavy rains wiped out much of play on Day 2. Only 7 men's singles were completed, and zero men's doubles matches. The good news? The roof made some play possible today. The bad news? Weather forecasts show at least a 40 percent chance of rain on three of the next six days.
