Wozniacki has been on a hot streak of late, and now she finds herself headed to one of tennis' biggest stages—albeit, not in the way she would have liked.

Peng was one of the tournament's Cinderella stories, defeating three ranked players—including No. 4 Agnieszka Radwanska—on her way to a semifinal showdown against the No. 10 seed. Unfortunately, she collapsed during the match due to heat and was forced to retire.

Live Tennis tweeted what many onlookers were feeling at the end of the match:

"

So Wozniacki is through 7-6(1), 4-3 (ret.) Not the way anyone would have wanted that to end but Wozniacki is into the final.

To that point, Wozniacki was ahead, but Peng was giving her a run for her money. Through the first set, neither was serving particularly well, but both players were showing a good amount of aggression. Peng won six of eight net points, while Wozniacki won seven of 11.

A late surge from Wozniacki and some unforced errors from Peng allowed the No. 10 to dominate the tiebreak and take the set.

The trend continued in the second set, but Peng began to show signs of slowing down. After just over two hours on the court, she couldn't continue. Wozniacki expressed her concern during a press conference, via USOpen.org:

"

Yeah, it was really hard to watch for me whenever I saw her collapse on the court. You know, tennis is great, but the health is more important. You know, to see her struggling out there, I just wanted to make sure she was okay. I got the word that she's okay now and just getting cooled down, so that's great to hear. I'm in the finals, which is obviously great. It's been five years for me since my last one here, so I'm extremely happy to be back there.

"

While the contest's conclusion provided a scary moment, in the end, Wozniacki moved on to the final. However, she had to await her fate, as the winner of the day's second match would advance as well.

Through three Slam events this year, Williams produced several flawless performances through the early rounds before suddenly faltering later in the tournament. She bucked that trend against Makarova on Friday.

As expected, Williams surged through several unranked opponents without dropping a single set. She continued to impress thereafter, winning in the quarterfinals and semifinals against quality opponents without dropping more than three games in any given set.

On Friday, Williams was brilliant against Makarova. The No. 1 seed remained consistent in every phase of the game. She served well, winning 77 percent of her first-serve points while accumulating five aces. She showed aggressiveness when the opportunity presented itself, and that resulted in winning all six of her possible net points. Williams also racked up 24 winners while keeping her unforced errors down to just 15.

Williams also showed her prowess on defense, allowing Makarova to gain just six winners and win one of three points at the net. The USTA tweeted Williams' dominant performance:

Makarova spoke of the difficulty dealing with Williams' aggressiveness during a press conference, via USOpen.org:

"

Well, Serena, she's a great, unbelievable player. It's always tough to play against her. Today she was so aggressive. I don't know. Maybe I didn't think that she will be that aggressive. Like she's just coming, you know, so early, so sometimes I was too late because she was too fast. I don't know. I'm still so happy that I was in semis.

"

With the final match now set, Williams will be looking to defeat Wozniacki in an effort to claim her sixth U.S. Open and 18th Grand Slam title. As for Wozniacki, some consider her the best player to never win a major tournament. One more victory in New York would change that.
