Thiem advances when Munar retires; Medvedev, Berrettini cruise
Second seed Thiem was leading Jaume Munar 7-6 (6), 6-3 when the Spaniard was forced to retire due to injury. The Austrian broke midway through the opening set to take a 3-2 lead only to see Munar rally and move within a game of taking the lead. Thiem regrouped and played a superb tiebreaker.
He took an early 2-0 in the second set and again Munar rallied, but at 3-3, he slipped on the court with Thiem proceeding to win 12 of the next 15 points, closing out to a two-set lead with his ninth ace before the world number 105 quit.
"I was happy with the way I was fighting, because it wasn't easy to play him", Thiem said after the contest. "The courts are very different this year, the court seemed to be slow inside (on Louis Armstrong Stadium). It was a little bit windy, but we had some good rallies. I felt I was playing good. I played a good tiebreak, which was pretty comfortable."
Medvedev routed Federico Delbonis 6-1, 6-2, 6-4 to close out play on Arthur Ashe Stadium. The Russian jumped out to a 5-0 first set lead before Delbonis got on the board, but he was immediately broken in the second set as Medvedev raced into a 4-0 advantage and eventually a two-set lead.
The third set was more competitive as Delbonis was more solid on serve to begin. However, when he was broken to fall behind 3-2, the match was over shortly thereafter as Medvedev improved his record to 9-3 at Flushing Meadows.
"I'm most pleased with the score, three sets", he said. "I'm happy that I finished before midnight. I was playing consistent and wasn't going for crazy shots....I managed to keep my distance and always kept pressure on his serve. That was the key."
Berrettini, a semifinalist here last year, knocked off Go Soeda 7-6 (5), 6-1, 6-4. The Japanese held a 5-3 lead in the first set tiebreaker before a double fault and a pair of baseline errors gifted the Italian the first set. The sixth seed won the next two sets with ease to finish with 48 winners and 18 aces.
"I was able to win the most important points in the tiebreak. I got a lot of confidence after winning the first set and I felt I could change gears", he said in his on-court interview after the match. "I got a little bit tight in the third set. I haven't played a lot of matches this year. It wasn't easy at the end, but mentally I was there and i'm happy with my performance."
