- Novak Djokovic pulled his championship tennis back together after last week's early exit, beating Gilles Simon 6-3, 4-6, 6-4 to reach the third round of the ATP-WTA Cincinnati Masters.
The world number one was ambushed at the same stage in Toronto a week ago by eventual champion Jo-Wilfried Tsonga.
But Djokovic made sure he did not commit the same error, despite being tested by his French opponent, who took the contest into a final set.
"He's not going to give you too many unforced errors and free points, so I knew that," Djokovic said. "But I managed to get a win in the end, and that's what matters."
In the only other second-round match played, Australian Open winner Stan Wawrinka was broken while serving for victory but pulled out a win over German Benjamin Becker 6-3, 7-6 (7/5).
Toronto winner Tsonga crashed back down to earth in his opening match, losing 6-1, 6-4 to Russian Mikhail Youzhny.
