It took Petra Kvitova four games to break Laura Siegemund twice. It was that kind of night for Kvitova, who closed out the second day and the first round of the 2015 US Open with a straight sets win over Siegemund.

No. 5 Kvitova, who won 6-1, 6-1 in 59 minutes, has never advanced past the fourth round at the US Open in her career, though she's been successful at other Grand Slams, winning Wimbledon twice. On Tuesday, Kvitova didn't look like a player who often falters at this particular tournament.

The first set took Kvitova just 25 minutes to wrap up. In that opening set, Kvitova converted on 9 of 12 points on her first serve while Siegemund only won 4 of 12 points on her first serve. 

The second set started better for Siegemund, who held serve in the first game. But on her second service game, Siegemund failed to win a single point and Kvitova was back in control. When Siegemund was given the chance to break Kvitova right back, she faltered. In the final set, Siegemund went 0 for 5 on her break point opportunities.

In the end, it was an easy win for Kvitova, who is looking to end her struggles at the US Open.

Young rallies back to stun No. 11 Simon

While other top seeds like Roger Federer and Andy Murray also cruised through their first-round matches at the 2015 US Open on Tuesday, perhaps the day's best action involved a seeded player going down.

It also involved a fantastic comeback.

No. 11 Gilles Simon surged ahead of Donald Young, winning the first two sets 6-2, 6-4. Simon then held a 3-0 lead over Young in the third set. But just when it seemed like Simon would close the door on Young, the 26-year-old American stirred back to life.

Young mounted his charge, taking the third set by winning six of the next seven games. Then he took the fourth set. Entering the fifth and final set, Young had a chance to knock off the highly-seeded Simon. And that's exactly what he did, winning the final set by a 6-4 score.

Despite the dire circumstances, it turned out to be a 2-6, 4-6, 6-4, 6-4, 6-4 win for Young.

"I was almost ready to go home there," Young said after the match.

Here's how to watch the best action on Wednesday. And below you can find the full results from Tuesday at the 2015 US Open.
