CAMERON Norrie failed to move past the first round of the BNP Paribas Open in Indian Wells after losing to Felix Auger-Aliassime.

The 23-year-old fell 6-3, 6-2 to the wildcard in just over hour.

The British No.2 dropped behind on his first service game in the opening set and failed to convert a break point to get back on serve five games later.

Auger-Aliassime, of Canada, broke twice more in the second set and overall won 80 per cent of his first-serve point to Norrie's 59 per cent.

Leonardo Mayer overcame wildcard Reilly Opelka to progress to the second round.

The Argentine battled past Opelka's big serve, prevailing 7-6 (6), 7-6 (2) despite facing 14 aces from the American.

Both players stayed on serve in the second set to force another tie-breaker, with Mayer outshining the world No.59 to wrap up the victory in one hour and 50 minutes.

Meanwhile, qualifier Marcos Giron, the world No.217, upset Jeremy Chardy, ranked No.37, overcoming the Frenchman 7-6 (3), 7-6 (1).

The American needed two hours to seal victory after both players held serve comfortably in the first set, with Giron claiming the first break in the fifth game of the second set.

Chardy maintained the pressure, forcing a second tie-breaker but ultimately was outclassed by Giron's serve in the decider.

Elsewhere, Sam Querrey needed three sets to defeat Matteo Berrettini 7-6 (5), 2-6, 6-4 and Jordan Thompson battled past Federico Delbonis 6-4, 6-7 (6), 7-6 (5).

Former Wimbledon semi-finalist Kirsten Flipkens, meanwhile, battled past Eugenie Bouchard to reach the second round of the WTP event.

The Belgian advanced after a three-set thriller lasting more than two and a half hours.

Flipkens had to use all her might to grab the opener after Bouchard drew level twice, with the American breaking Flipkens twice in the second and setting up the decider that lasted more than an hour.

Serving for the match at 5-4, Flipkens displayed mental strength when Bouchard grabbed a break, going on to win the last two games and clinching the victory 7-5, 3-6, 7-5. She will now face No.25 seed Danielle Collins.

Meanwhile, Venus Williams moved past Andrea Petkovic 6-4, 0-6, 6-3 to set up a second-round match against world No.3 Petra Kvitova.

After a dominant second set by Petkovic, Williams quickly turned things around at the start of the third, breaking Petovic in the first game and racing to a 4-1 lead.

Williams stumbled at 5-2, missing the opportunity to take the match, but broke straight back to wrap up the win in one hour and 46 minutes.

Monica Puig, Madison Brengle and Kristina Mladenovic also advanced to the next round.
