US Open Tennis 2015 Results: Early Tuesday Results, Highlights and Scores Recap

The 2015 U.S. Open continued on Tuesday, with dominating performances from top-ranked stars and stunning upsets that changed the dynamic of the tournament.

Lucie Safarova, who entered as the No. 6 seed on the women's side and was coming off a finals appearance at the Connecticut Open last week, was ousted in straight sets 6-4, 6-1 by Lesia Tsurenko. 

On the men's side, No. 11 Gilles Simon will join Safarova in going home earlier than expected. He blew a two-set lead and was knocked off by Donald Young 2-6, 4-6, 6-4, 6-4, 6-4. It was a huge win for American men's tennis, which hasn't had a player win a major tournament since Andy Roddick in 2003. 

While there's still a long way to go before declaring men's tennis in the United States back, things are off to a good start. Here's a look at all the early results from the second day of action in New York, as well as a more detailed analysis of the key matches.

Tuesday Recap

Young's win over Simon was stunning for many reasons, not the least of which is the way he survived after losing the first two sets. 

Nick McCarvel of USA Today provided numbers from the ATP World Tour that highlight how improbable Young's advancing was:

In an on-court interview after the match, per the Associated Press (via FoxSports.com), Young admitted things were bleak. 

"I was almost ready to go home there," Young said. "I had nothing to lose." Young added of how he started going after his shots in the third set. "He was kicking my butt."

Young did learn how to handle ranked opponents leading into the U.S. Open, knocking off Tomas Berdych in the second round at the Rogers Cup three weeks ago. He had a misstep after that, losing in the first round at the Winston-Salem Open, but the Berdych win certainly helped pave the way for what happened on Tuesday. 

Roger Federer got his quest for a sixth U.S. Open title got off to a rousing start, as the No. 2 seed breezed past Leonardo Mayer 6-1, 6-2, 6-2. 

Anyone watching could tell Federer was feeling good when he hit this shot to end the second set, per U.S. Open Tennis on Twitter:

It was a dominating performance by Federer, who had 12 aces and won 84 percent of his first serves. The 34-year-old has gone through a progression in this year's Grand Slam events, losing in the third round at the Australian Open before reaching the quarterfinals at the French Open and finals at Wimbledon. 

Federer has been building momentum coming into the U.S. Open, defeating Novak Djokovic in the Western and Southern Open finals on Aug. 23. 

Stuart Fraser of the Daily Mail was able to put Federer's win over Mayer, who is ranked 34th in the ATP rankings, in proper context:

It was also a historic win, as ESPN Tennis noted Federer's 73-match wins at the U.S. Open are tied with Ivan Lendl for third most in the Open Era. 

Safarova's loss continues a disturbing trend for women seeded in the top 10 at this tournament, per ESPN Stats & Info:

There is a good reason Safarova struggled on Tuesday before succumbing to defeat, as TSN's Mark Masters noted she was dealing with an abdominal tear that also forced her to pull out of doubles competition with Bethanie Mattek-Sands. 

Simona Halep, the No. 2 seed on the women's side, had an easy day when a knee injury forced Marina Erakovic to retire down 3-0 in the second set. 

With all of the withdraws and upsets on the women's side thus far, Halep is the biggest threat to Serena Williams' quest for a Grand Slam at this stage of the tournament. 

The 23-year-old said after her opening-round win that she is in a better place physically and mentally than in the season's previous majors, per WTATennis.com:

"I play better when I feel a little bit of pressure, because I'm always very focused, but now it's in the middle," Halep said. "I feel pressure, but still I have no expectations. So I feel great. I'm much better than I was at the other Grand Slams. Much better."

Halep has reached the finals in each of her last two events, though she's been unable to close things out. Williams defeated her at the Western and Southern Open, and Belinda Bencic upset her at the Rogers Cup. 

Another women's player with big hopes at the U.S. Open is Caroline Wozniacki. She got off to a strong start with a straight-set win over Jamie Loeb, 6-2, 6-0. 

This has historically been Wozniacki's best major tournament with two finals appearances, including a loss to Williams last year. She has had an erratic 2015 season thus far, owning a 33-17 match record coming into Tuesday. 

However, per ESPN Tennis, there was little cause for concern about Loeb being able to pull off an upset in this spot:

There also seems to be a different vibe around Wozniacki as she's matured physically and mentally, even bringing a sense of humor to the proceedings when John Isner's press conference ran long, per Douglas Robson:

With four women in the top 10 already going down, things have opened up for players like Halep and Wozniacki to challenge Williams as the tournament moves into the later rounds. They will have to avoid finding the banana peel as well, but there's no reason those two shouldn't be favored in every match before the quarterfinals. 

It also speaks to the level of parity present in women's tennis today. Williams is alone at the top of the food chain, but beyond her there isn't another dominant female who stands above the rest. 

Tuesday's early session was about establishing the tone for this year's U.S. Open. Even with the upsets, the key players who were expected to challenge for a championship showed why they belong on that short list.
