The 2020 U.S. Open is nearing its conclusion. After more than a week of exciting action, the fields are down to the last four in both the men's and women's singles tournaments. But the best may still be to come.

On Thursday, the women's tournament will have the spotlight when a pair of semifinal matchups will determine who progresses to Saturday's final.

First, No. 4-seeded Naomi Osaka will play No. 28-seeded Jennifer Brady at 7 p.m. ET. Then, No. 3 seed Serena Williams will take on unseeded Victoria Azarenka at 9 p.m. ET.

Williams is a six-time U.S. Open champion, while Osaka won the tournament in 2018. Brady and Azarenka have never won the event.

Here's a look at Thursday's broadcast schedule, followed by predictions for the women's semifinals.

Women's Semifinal Predictions

Osaka Continues Roll, Wins in Straight Sets

Despite a left hamstring injury, Osaka is having her best showing at a major tournament in more than a year. After winning the 2018 U.S. Open and 2019 Australian Open for her first two career Grand Slam titles, she didn't make it past the round of 16 at her next four appearances at major events.

At this year's U.S. Open, though, the 22-year-old has reminded everybody why she's one of the top players in the world. She faced a little adversity early, with two of her first three matches going to three sets. But she's won each of her past two matches in straight sets, defeating No. 14 seed Anett Kontaveit and Shelby Rogers, both by scores of 6-3, 6-4.

Now, Osaka will face Brady, who has won each of her first five matches in straight sets, including victories over No. 17-seeded Angelique Kerber and No. 23 seed Yulia Putintseva in the past two rounds.

However, things are about to get a lot tougher for the 25-year-old. She beat Osaka in 2014 and lost to the same opponent four years later.

"She's a really amazing player," Osaka said, according to Richard Osborn of USOpen.org. "She has the variety that I wish I had, so I'm a bit jealous. I think it's going to be a really tough match."

But Osaka is a much better player than when she lost to Brady six years ago. And while the American may get off to a solid start Thursday, expect the Japanese player to take control at some point in the first set and go on to win in straight sets.

Osaka should begin to dominate the match with her serves, making it hard for Brady to stay in it.

Serena Again Reaches U.S. Open Final

A day after winning her quarterfinal, Williams will return to the court Thursday to take on Azarenka with a spot in the U.S. Open final on the line.

It's a scenario that Williams knows well. In addition to being a six-time tournament champion, she has also reached the final each of the past two years, although she lost both times.

The 38-year-old will hope this year is different. She hasn't won a Grand Slam title since the 2017 Australian Open, leaving her one shy of the all-time record of 24 held by Margaret Court.

Before potentially playing in the final again, though, Williams will need to beat Azarenka, a two-time Australian Open champion who also reached the U.S. Open final in 2012 and 2013. And although the Belarusian was unseeded in this year's tournament, she's only lost one set through her five matches.

The 31-year-old has also defeated three seeded opponents: No. 5 Aryna Sabalenka, No. 16 Elise Mertens and No. 20 Karolina Muchova. However, Williams will be her toughest test yet.

The semifinal rivals are no strangers as they've played 22 times before, with 18 of those matches being won by Williams. Williams has won six of her past seven matches against Azarenka, which includes the last time they faced each other in 2019.

Expect this match to go in similar fashion. Williams may drop either the first or second set (as she's done in each of her past three U.S. Open matches), but she'll find a way to pull out the victory in the final set.

Williams will then go on to face Osaka in a rematch of the 2018 U.S. Open final that has the potential to be the best match of the tournament.
