US Open Tennis 2016 Results: Winners, Scores, Stats for Thursday Singles Bracket

The 2016 U.S. Open rolled on Thursday with more second-round action in both the men's and women's draws at the season's final Grand Slam event. Serena Williams, Andy Murray, Stan Wawrinka and Simona Halep were among the notable players on the Day 4 slate.

Rain delayed the action on the outer courts at the beginning of the day before finally clearing up shortly after noon local time in Queens, New York. Another delay followed later in the afternoon. The Weather Channel forecast suggests it shouldn't be a consistent problem over the next couple of weeks, though.

Let's check out the complete list of scores from Thursday, which we will update through the conclusion of play at the USTA Billie Jean King National Tennis Center. That's followed by a recap from some of the day's key matches.

Day 4 Recap

Halep has endured a lackluster campaign on the Grand Slam stage. The Romanian star got knocked out in the first round of the Australian Open and the fourth round of the French Open. She did reach the quarterfinals of Wimbledon, but that's merely the baseline for success as a top-five player.

The early returns in New York suggest she could end on a high note, though. After crushing Kirsten Flipkens in her opener, she secured another straight-sets triumph Thursday against Lucie Safarova. That's a tricky start to a tournament, so getting through without dropping a set is a good sign.

WTA Insider noted that the win over Safarova wasn't quite as routine as the scoreline may suggest, though:

That said, Halep was able to limit her errors (20 compared to 44 for her opponent) and served well (71 percent on the first serve and four aces). She's a legitimate title contender if she can maintain that steady defense and clutch serving.

Murray is also looking strong in the early going, as he quickly dispatched Marcel Granollers to reach Round 3. Like Halep, he wasn't gifted an easy draw at the outset with Lukas Rosol and Granollers, but there have been no signs of a letdown.

The three-time major champion struggled to get his first serve in play Thursday (43 percent), but every other facet of his game looked strong. His winner-to-error ratio was plus-six, and he won 44 percent of the points on the return.

He also moved around the court with his trademark quickness, as U.S. Open Tennis highlighted:

All signs point toward him moving through his quarter of the draw without much drama. But he's still got a lot to prove in an event where he hasn't advanced beyond the quarterfinals since winning his first Grand Slam title in New York in 2012.

Venus Williams made quick work of Julia Goerges to advance. Williams' play has been a bit up and down during the course of the season, but it feels like she's still got one more magical run in her at a major, and it could happen over the next few weeks.

ESPN Stats & Info spotlighted her success at the U.S. Open:

As always, there's no doubt about her ability, which remains right there with some of the best players in the world. The question is whether she can hold up physically for the duration of the event. So far, everything is trending in the right direction.

Her sister Serena kicked off prime time on Thursday night with a straight-sets win over fellow American Vania King, 6-3, 6-3. 

On a night when Williams had difficulties navigating her opponent's serve, she was able to use her own powerful serve to fuel her to victory. 

Williams recorded 13 aces on the evening in what was a milestone win, via the WTA:

It wasn't a perfect night, though, as she recorded 28 unforced errors.

Now, the world's No. 1 player will meet Johanna Larsson of Sweden in the third round, a player she has beaten twice before in two matches, as she'll look to correct her game and continue her dominance at the U.S. Open.
