Former No. 1 singles players Serena Williams and Caroline Wozniacki advanced to the semifinals at the ASB Classic in their first tournament as doubles partners. The pair beat top-seeded Johanna Larsson and Caroline Dolehide 6-2, 6-1 in the second round. Wozniacki says “we're just having a great time.” But the pair will not play together at the Australian Open. Wild-card entry Eugenie Bouchard progressed to the singles quarterfinals with a 6-4, 6-4 win over eighth-seeded Caroline Garcia.
