Ivanovic downed Flavia Pennetta 7-6 (9), 6-1, while Jovanovski beat Sorana Cirstea 6-3, 6-2.
In the doubles, wildcard entrants Serena and Venus Williams wasted chances to win before losing 6-7 (3), 6-4, 11-9 to Liezel Huber and Chan Hao-ching.
In the men's draw, Australia's Bernard Tomic opened with a 7-6 (4), 6-4 win over China's Zheng Ze.
