Eugenie Bouchard suffered a second consecutive first-round loss as she crashed out of the Luxembourg Open to Denisa Allertova.

Fourth seed Caroline Garcia was made to work hard for a 7-6 (7/2) 2-6 6-4 win against Anett Kontaveit, while wildcard Francesca Schiavone upset fifth seed Laura Siegemund.
Yanina Wickmayer failed to recover from a nightmare first set as she went down to Anna Karolina Schmedlova, ranked 99 places below her in 152nd, 6-0 1-6 6-3.

Home favourite Daria Kasatkina kicked the Kremlin Cup off with a straight sets victory over Belinda Bencic in Moscow.
The number eight seed saw off her Swiss opponent 6-4 6-1 in just over an hour to book a spot in the second round.
Ninth seed Timea Babos was made to work harder against Romania's 2014 finalist Irina-Camelia Begu, eventually coming through in three sets 6-2 6-7 (2/7) 7-5.
The two battled for almost two-and-a-half hours before Babos claimed the win, while qualifiers Lesia Tsurenko, Katerina Siniakova, Anna Blinkova and Nicole Gibbs secured spots in the main draw.
