MELBOURNE, Australia (AP) — Stanislas Wawrinka was the first man through to the second round at the Australian Open, advancing after just 15 games Monday when Andrey Golubev retired with an injured left leg.

The No. 8-seeded Wawrinka, who lost 12-10 in the fifth set to eventual champion Novak Djokovic in the fourth round here last year in the longest Grand Slam match of 2013, was leading 6-4, 6-1 when his Kazakhstan rival quit. Golubev took a medical time out and had his lower left leg taped when he was down 5-2 in the first.

Wawrinka won the Chennai Open in India to start 2014 and is one of the big threats on the bottom half of the draw that includes three-time defending champion Djokovic and No. 3 David Ferrer. Wawrinka was only on court for 65 minutes and played 91 points, a lucky break at the start of the week where temperatures are expected to be steamy.

No. 18-seeded Kirsten Flipkens, a Wimbledon semifinalist last year, was the first woman to advance when she beat Britain’s Laura Robson 6-3, 6-0. In another fast-finishing first-rounder, Karolina Pliskova of the Czech Republic had a 6-0, 6-1 win over French wildcard Pauline Parmentier.

Flipkens made only four unforced errors against 32 for Robson, who was ranked 48th and knocked out 2011 Wimbledon champion Petra Kvitova in reaching the third round at last year’s Australian Open.

In other first-round matches, Venus Williams was on court against No. 22 Ekaterina Makarova and top-ranked Serena Williams had a night match against Australian teenager Ashleigh Barty.
