Cincinnati Open results
France's Jo-Wilfried Tsonga suffered a surprise defeat to qualifier Alex Bogomolov while Spain's Rafa Nadal and world number one Novak Djokovic passed their second-round tests at the Cincinnati Open on Wednesday.
France's Tsonga, a semi-finalist at Wimbledon, fell to the 28-year-old Florida-based, Moscow-born Bogomolov 6-3 6-4.
Bogomolov, who yet to win on the ATP Tour and ranked 50th, made a name for himself this year with a surprise win over Andy Murray in Miami and he now gets another shot at the Briton in the third round.
"I learned a lot about myself during that match just because it was a lot of pressure. It was my hometown. It was on the stadium where I grew up in Miami," said Bogomolov.
"Now it's a little bit different. It's a third round of a Masters Series instead of a second round but we're going to have the same game plan going in."
Djokovic moved his season record to 54-1 with a 6-2 6-3 victory over Ryan Harrison.
The Serb now has a 30-0 record on hardcourts after recovering from an early break from 19-year-old Harrison.
"It was a slow start, not a good start. I wasn't serving so great today but I think everything else was quite good.
"From the baseline I wasn't making a lot of unforced errors.
I was returning a lot of balls in and played quite good really for the opening match."
Both Murray and Nadal suffered early exits at the Montreal Masters last week but there was little hint either would fall to the same fate on Wednesday.
Murray, the fourth seed, overcame a sluggish start to record a 6-4 6-1 win over Argentine David Nalbandian, setting up a third-round match against Bogomolov.
"I was definitely better today than last week," said Murray.
"I need to try and keep that up for the next match and hopefully play just five, ten percent better tomorrow than I was today."
World number two Nadal also put last week's setback aside, beating French qualifier Julien Benneteau 6-4 7-5 in just over 90 minutes.
The Spaniard won all three break points he gained in a comfortable display and will now face compatriot Fernando Verdasco, who beat France's Michael Llodra 6-4 6-4.
Nadal was forced to play with bandages on two fingers on his right hand, which he said were the result of handling a hot plate at a restaurant and suffering blisters.
Germany's Philipp Kohlschreiber followed up his first round win over Andy Roddick with a 6-1 6-4 win over Spain's Feliciano Lopez.
