LONDON — Serena Williams hardly broke sweat in the Wimbledon heat as the world number one cruised into the third round with a 6-4, 6-1 victory over Hungary's Timea Babos on Wednesday. With sweltering temperatures reaching a Wimbledon record 35.7C (96.2F), five-time champion Williams kept her cool to dispatch world number 93 Babos with 12 aces and 23 winners in just 59 minutes on Centre Court. The 33-year-old, bidding for a third Grand Slam title of the year, will play Britain's Heather Watson for a place in the last 16. Wawrinka eases through with minimum fuss Stan Wawrinka moved seamlessly into the Wimbledon third round on Wednesday, wasting little energy to secure a 6-3 6-4 7-5 win over Victor Estrella Burgos in the evening sunshine on Court One. The French Open champion and winner of two of the last six grand slams strolled off court after a volleyed put-away clinched victory in an hour and 31 minutes. The fourth-seeded Swiss has only once reached the quarter-final at Wimbledon, losing to compatriot Roger Federer last year, and will face Spaniard Fernando Verdasco in the third round on Friday. — Agencies
