21-time Grand Slam champion Serena Williams began hitting her stride on Sunday’s edition of the International Premier Tennis League, winning a 6-3 set of women’s singles against former No.1 Ana Ivanovic.

Williams made her first appearance in the match playing mixed doubles with Treat Huey, and though she dropped a tight set of mixed doubles to 2013 Wimbledon and 2014 Australian Open champions Kristina Mladenovic and Daniel Nestor, the American recovered well in the very next set against Ivanovic, taking just 25 minutes to dispatch the Serb and make way for a 29-18 victory for the Philippine Mavericks over the OBI UAE Royals.

In the other match played in Manila’s Mall of Asia Arena, Belinda Bencic was equally emphatic for the OUE Singapore Slammers, winning both of her sets in women’s singles and mixed doubles with Nick Kyrgios en route to a 29-20 win against the Legendari Japan Warriors. Emerging for the former against Mirjana Lucic-Baroni, the reigning Rogers Cup champion helped turn the tide towards the Slammers with a 6-2 victory before partnering Kyrgios to close the door, 6-3, against Lucic-Baroni and partner, Pierre-Hughes Herbet.
