Winston-Salem, N.C. - The late afternoon match between 8th seeded Juan Monaco and 10th seed Alexandr Dolgopolov was an anticipated one. It did not fail to deliver, going three sets.

It was a match that went back and forth with both players struggling to hold serve. Dolgo only placed 49 percent of his first serves in play. Monaco served better but could not hold his serve facing 14 break points. Dolgopolov capitalized breaking serve 6 times.

In the first set Dolgo seemed to be playing up hill throughout. After breaking Monaco to go to 4-6, he could not hold serve and Monaco took the first set.

In the second set, each player broke serve early but when Dolgopolov went to 3-1, he was able to gain control of the set and went on to take the second set at 6-3, forcing a third.

In the third,, Monaco broke to go up 3-1 but Dolgopolov was able to make hay on his return of serve and broke 3 consecutive games on Monaco's racket. He did not lose another game taking the third set 6-3.

Dolgopolov has struggled a good portion of 2013 and seen his ranking drop into the 30s. But the young Ukrainian is dangerous when he is on and could be a threat in the upcoming U.S. Open.

He will face Yen Hsun-Lu in the quarterfinals on Thursday.
