LONDON, Great Britain - After byes in the opening round, the top two seeded teams in mixed doubles at Wimbledon opened their tournaments in contrasting fashion on Saturday.
Martina Hingis, the top seed in the draw alongside Jamie Murray, moved through to the third round with the loss of just three games, defeating Neal Skupski and Anna Smith, 6-3, 6-0.
On the bottom of the draw, No.2 seeds Elena Vesnina and Bruno Soares were pushed all the way by Americans Jack Sock and Madison Keys, but came through the challenge, 6-3, 3-6, 7-5, from a break down in the decider.
Defending champions Heather Watson and Henri Kontinen look to follow up last year's fairytale with a deep run this year, and the Brit and Finn knocked off No.13 seed Anna-Lena Groenefeld - who they conquered in last year's championship - and her new partner Aisam-ul-Haq Qureshi in just 49 minutes, 6-1, 6-3.
Though British teams were very successful in the opening round of the mixed doubles competition, two of the three all-British teams were sent out of the draw against seeded teams on Saturday. Other than Watson, though, the home crowd saw Jocelyn Rae and Ken Skupski score an upset over No.5 seeds Andrea Hlavackova and Edouard Roger-Vasselin, 6-4, 7-5.
In total, four seeded teams fell at the first hurdle on Saturday, including the last match of the first week at the All-England Club - as No.6 seeds Casey Dellacqua and Rajeev Ram and Nicole Melichar and Andre Bergamnn played deep into a decider.
After the American and the Aussie rolled through the first set, the unseeded duo battled back, and - after saving a match point at 5-6 in the final set - eventually came out on top, 1-6, 6-3, 15-13 in two hours, 24 minutes.
Also scoring an upset against a seeded team was Croat Ana Konjuh and her partner Nikola Mektic - the 19-year-old is still alive in all three disciplines at the All-England Club, as she and her compatriot defeated No.8 seeds Chan Hao-ching and Jean-Julien Rojer, 6-4, 7-6(5).
Roland Garros champions and No.10 seeds Gabriela Dabrowski and Rohan Bopanna had a winning debut as major champions with a 7-6(2), 7-5 win over Raluca Olaru and Fabrice Martin.
In Paris, Dabrowski became the first Canadian woman to win a Grand Slam and she and Bopanna were unseeded, and went all the way to the title.
No.4 seed Sania Mirza and her partner Ivan Dodig, No.9 seed Abigail Spears and partner Juan-Sebastian Cabal, No.12 seed Eakterina Makarova and partner Max Mirnyi also all remained on course in the draw and moved on to the third round in straight sets.
