Novak Djokovic made it safely into the third round of the Indian Wells ATP Masters on Sunday, but said his straight-sets win over Victor Hanescu left room for improvement.
The world number two and second seed, a two-time winner in the California desert, saved all five break points he faced on the way to a 7-6 (7/1), 6-2 victory.
He didn't get a break chance in the opening set, but dominated the tiebreaker and took a quick 3-0 lead in the second. He said he'd be working on a few things before his third-round match against Colombian Alejandro Gonzalez, a 6-4, 2-6, 7-6 (7/5) winner over Croatian Ivan Dodig.
Roberto Bautista Agut of Spain bounced fourth-seeded Tomas Berdych 4-6, 6-2, 6-4.
Second-seeded Agnieszka Radwanska of Poland led the way into the women's fourth round of the $12 million combined WTA and ATP Masters tournament.
Radwanska, ranked third in the world, thumped 48th-ranked German Annika Beck 6-0, 6-0.
