Roger Federer takes on Thomaz Bellucci tonight at the BNP Paribas Open in Indian Wells (23:30 GMT start).
Federer was given a bit of a scare on Tuesday as Milos Raonic threatened to end his winning streak. The Swiss admitted that the confidence he has from winning back-to-back tournaments last month had helped him to pull through, 6-7 6-2 6-4.
"I guess my experience helped me to stay calm and just weather the storm," said Federer.
"Maybe if I would be younger I'd be more panicky about him hitting aces left and right and making me feel uncomfortable. I have been there so many times before against some of the all time great servers that it was obviously not going to happen tonight. I just hoped to stay calm."
Bellucci may be unseeded and ranked 50 in the world but he's proved his mettle in Masters events in the past, beating Andy Murray and Tomas Berdych en route to the Madrid semis last year. However it's rare to see him doing this well on hard courts. He benefited from Nikolay Davydenko's withdrawal prior to their scheduled third round clash, but it's hard to see him going any further in the competition.
Prediction: Federer in two.
