MELBOURNE, Australia (AP) — Roger Federer relied on his Grand Slam experience during the most important points to beat Noah Rubin 7-5, 6-3, 7-6 (3) on Wednesday, maintaining his record of never failing to reach the third round at the 18 Australian Opens he’s contested.

After back-to-back wins over qualifiers, the degree of difficulty in his comeback from a six-month injury layoff will increase exponentially. Next up he faces 2010 Wimbledon finalist Tomas Berdych, who had a 6-3, 7-6 (6), 6-2 win over Ryan Harrison.

Also looming, potentially, is No. 5 Kei Nishikori, the 2014 U.S. Open finalist, who set up a third-round match against Lukas Lacko with a 6-3, 6-4, 6-3 win over Jeremy Chardy.

Federer didn’t play after his semifinal exit at Wimbledon last year, resting his injured left knee. He returned at the Hopman Cup exhibition in Perth this month, and opened at Melbourne Park with a win over another 35-year-old veteran, Jurgen Melzer.

Against Rubin, a 20-year-old qualifier and 2014 Wimbledon junior champion, the 17-time Grand Slam winner played the big points like the old pro that he is.

Rubin had his chances in the third set, breaking Federer in the second game and having two set points on the Swiss star’s serve when he led 5-2.

But Federer upped the tempo, winning four of the last five games to force a tiebreaker, which he dominated. Rubin moved well from the baseline, and hit 11 forehand winners, but was only able to convert one of his six break-point chances.

“I definitely got lucky winning that third set. He had a couple of set points on my serve,” Federer said. There were, “a lot of difficult points, which is what I need.”
