Two-time champion Petra Kvitova was an easy first-round winner, while No. 2 seed Simona Halep and last year's runner-up Genie Bouchard were a pair of upset victims Tuesday at The Championships.
Winning 28-of-29 points on serve, the formidable second-seeded Czech left-hander Kvitova flattened Dutchwoman Kiki Bertens 6-1, 6-0 at the All England Club.
