INDIAN WELLS (REUTERS) - World No. 2 Andy Murray was given a tough test but pushed his way past Marcel Granollers 6-4, 7-6 (7-3) in his opening match at the BNP Paribas Open in California on Saturday.
Murray had led Great Britain to a Davis Cup victory over Japan last week, but apart from that team event, had not competed since his Australian Open final loss to Novak Djokovic on Jan 31.
He has made plenty of news off the court since then, however, welcoming the birth of his first child last month and last week rebuking Maria Sharapova for her drug test failure.
On the court in Indian Wells on Saturday, he overcame a break in the first set, and then took the second in a tiebreak against his Spanish opponent.
Earlier, Canadian Milos Raonic took only 55 minutes to dispatch Inigo Cervantes.
In other second-round action, sixth seed Tomas Berdych cruised past Juan Martin del Potro 7-6 (7-4), 6-2.
Frenchman Gael Monfils and Richard Gasquet both advanced, while controversial Australian Nick Kyrgios was docked a point for swearing in his loss to Albert Ramos 7-6 (7-4), 7-5.
On the women's side, Australian Open champion Angelique Kerber was upset by Denisa Allertova of the Czech Republic 7-5, 7-5.
Second seed Kerber has been in a bit of slump since beating Serena Williams in the Australian Open final, losing three of her past four matches.
She was not the only high seed to fall, however, as fourth seeded Garbine Muguruza of Spain went down to American Christina McHale 7-5, 6-1.
Muguruza struggled with her serve and was broken five times.
