<div>Stan Wawrinka avoided becoming the first defending champion to lose first round at the French Open on Monday when he battled past combative Lukas Rosol in five tough sets.<br /><br />Third seed Wawrinka fired 56 winners but committed 46 unforced errors and saved eight break points to book a second round clash against Japan's Taro Daniel.<br /><br />Wawrinka, 31, had defeated 59th-ranked Rosol in the semi-finals of the Geneva clay-court tournament just last Friday.<br /><br />But Rosol went into the match on a chilly Court Philippe Chatrier with the pedigree of having famously stunned Rafael Nadal at Wimbledon in 2012.<br /><br />That free-swinging masterclass almost paid dividends again Monday but once he had let slip two break points at 2-2 in the fourth set, his hopes slowly slipped away.<br /><br />Spanish fourth seed Garbine Muguruza was also struggling on Court Suzanne Lenglen, coming back from a set down to defeat Slovakia's Anna Karolina Schmiedlova 3-6, 6-3, 6-3.<br /><br />Muguruza, who has made the quarter-finals for the last two years, will take on French wildcard Myrtille Georges, the world number 203, for a place in the last 32.<br /><br />But the 22-year-old Wimbledon runner-up was far from impressive in the two and a half hour encounter.<br /><br />After dropping the first set, Muguruza had to save nine break points just in the opening game of the second set.<br /><br />She then allowed her 37th-ranked opponent, who has won just one match all year, to claw her way back from 0-4 down to 3-4 in the decider before the Spaniard settled herself to see out the win.<br /><br />Muguruza fired 44 winners but hit 53 unforced errors and had to save 17 of 21 break points. Play started two and a half hours late Monday because of more rain with 12 of the 66 scheduled matches pushed back to Tuesday.<br /><br />However, there was plenty of time for notable firsts. Qualifier Cagla Buyukakcay beat Aliaksandra Sasnovich of Belarus 5-7, 7-6 (7/2), 6-2 to become the first Turkish woman in the Open era to reach the second round of a Grand Slam.<br /><br />The 26-year-old Buyukakcay, ranked at 83, had earlier this clay-court season become the first Turk to win a WTA title when she triumphed in Istanbul.<br /><br />Japan's Naomi Osaka won her first match at Roland Garros with a 6-4, 7-5 triumph over Latvian 32nd seed Jelena Ostapenko.<br /><br />Elsewhere, Canadian eighth seed Milos Raonic, a 2014 quarter-finalist, defeated Serbia's Janko Tipsarevic 6-3, 6-2, 7-6 (7/5). Tipsarevic, ranked at 686, was playing his first Roland Garros since 2013 after being treated for a benign tumour on his left foot.<br />Japanese fifth seed Kei Nishikori beat Italy's Simone Bolelli 6-1, 7-5, 6-3 on Court Philippe Chatrier on Sunday.<br /><br />Victory gave the 26-year-old Japanese his 50th Grand Slam win. Russia's Svetlana Kuznetsova, the 2009 champion, won her resumed match against Yaroslava Shvedova of Kazakhstan 4-6, 6-1, 6-4.<br /><br />There was also a win Monday for Croatia's Mirjana Lucic Baroni who first played the main draw in Paris in 1999. The 34-year-old knocked out 33-year-old Daniela Hantuchova of Slovakia 6-1, 6-2.</div>
