The second seed Caroline Wozniacki is off to a great start in New York, defeating Samantha Stosur 6-3 6-2 in an hour and 24 minutes, notching her 36th win at the US Open. The Dane dominated on the return, converting five out of nine break points and giving her serve away only once to control the scoreboard all the time.
Stosur had more winners but also much more errors and she couldn't keep the pace with the better-ranked opponent who was more focused in the closing stages of both sets to book her place in the second round. Caroline earned a break in the third game of the match and she fends off a break chance in the following game to create a 3-1 gap.
Stosur broke back in game six but that was all we saw from her in the opener, losing the next three games to hand the opener to Wozniacki 6-3 after breaks for the Dane in games seven and nine. Samantha survived three break points in the fourth game of the second set but Caroline rattled off 15 of the last 20 points and four straight games to cross the finish line and move forward.
2016 US Open champion Angelique Kerber toppled Margarita Gasparyan 7-6 6-3 in an hour and 45 minutes to kick off the tournament in a good fashion. The Russian fought great in the opening set, saving three set points in game 10 to set up a tie break where she was two points from claiming it.
Kerber stayed focused to bring the set home after all and she prevailed with two breaks in set number two. Both players had more winners than unforced errors and we saw seven breaks overall, four from Kerber and three from Gasparyan who couldn't make another push in the second set after wasting break points in game five.
After a slow start, Kerber won four games in a row for a 4-2 lead, including breaks at love in games three and five. Serving for the opener at 5-4, the German squandered three set points and the result was leveled at 5-5, entering a tie break after two good holds on both sides.
Angelique was 3-0 and 5-4 down but she managed to win the last three points of the breaker for a 7-5, mighty relieved as she certainly didn't want to kick off the tournament in a losing way. They traded breaks at the start of the second set and Margarita had two break points in game five that could have sent her in front.
Instead of that, Kerber brought that game home and she made the crucial move when she broke in the eighth game, sealing the deal with a hold at 15 a few minutes later for the place in the second round. First round results:
