Day four of the French Open saw the start of the second round matches, highlighted by Andy Murray and Stan Wawrinka on the men's side, and featuring Agnieszka Radwanska, Garbine Muguruza, Simona Halep and Petra Kvitova on the women's.
Here's a roundup of the action from Wednesday at the French Open.
Murray struggles on otherwise untroubled day for seeds
Murray was the biggest name in action on day four, up against the unheard of Mathias Bourgue for a place in round three. Bourgue had never played a match above Challenger Tour level until this tournament, and was expected to submit easily to get Murray's campaign back on track after near defeat in round one.
However, some inspired play from the Frenchman alongside some baffling indifference from Murray saw Bourgue take a two sets to one lead - at one point winning six games in a row against the world number two.
As he has done so often, though, Murray was able to raise his game for the conclusion of the match, and eventually managed to overcome an opponent who had never played more than three sets before.
Stan Wawrinka was much improved from his first round match, overcoming Taro Daniel in three sets while hitting 62 winners. The defending champion will be delighted to find some form as he continues what seems unlikely to be a successful title defence.
In fact it was a strong day for seeded players overall, Kei Nishikori, Richard Gasquet and Milos Raonic also posting straight sets wins, while Ivo Karlovic eventually won his match with a 12-10 final set. John Isner put an end to Kyle Edmund's hopes with a straight-forward three set win over the British number three.
Benoit Paire at 19 was the highest ranked player to fall, Lucas Pouille the only other seeded player to be ousted.
Muguruza leads dominance of WTA elite
Muguruza put in the most impressive performance on the women's side, with a destructive 6-2 6-0 win over Myrtille Georges. The Spaniard lost just nine points on serve and broke her opponent five times in an incredibly one-sided match. Georges managed to win just 35% of points on her own serve, and gave up 22 unforced errors.
The women's seeds were just as dominant as their male counterparts, Kvitova, Radwanska - who defeated talented youngster Caroline Garcia - and Halep all posting straight sets wins on a day lacking in upsets.
Former champion Svetlana Kuznetsova put an emphatic end to British interest in the women's draw with a 6-3 6-1 destruction of Heather Watson. The often underestimated Russian has made an excellent start to the tournament, and could be a dark horse as the fortnight progresses.
The only seeded player to be defeated on day four was Ekatarina Makarova, who went down in three sets to former world number 12 Yanina Wickmayer.
