Andy Roddick defeated Jeremy Chardy 6-4, 7-6 to advance to the quarterfinals at the Japan Open.
Roddick said Chardy is “always dangerous because he plays high-risk tennis” but felt more assured when forced into longer rallies.
The American served only five aces but won 83 percent of his first serve points.
Roddick took the lead when he broke Chardy in the third game of the first set and thta was all he needed to claim the set.
Chardy stood firm in his service games and did not give the American another break opportunity until the tie-break.
Chardy had set point in the 10th game of the second set at 5-4 and 30-40 but failed to converted while Roddick then claimed two mini-breaks in the tie-break to lead it 6-2 and won the match on his second macth point.
"I was pretty happy with the way I played. I felt I played the big points really well. I felt today was pretty encouraging," said Roddick.
"He is always dangerous, because he plays very high-risk tennis. At that point (second set 10th game), I wanted to take service points, but he went for big shots and all of a sudden I played a bad game and I was down 30-40.
"I was able to maintain aggressive tennis and got to the net and hit a pretty good volley to the corner. I was able to get out and close it out," added Roddick.
