Here are my predictions for the women's quarterfinals at the 2019 U.S. Open Championships. I have also predicted the men's quarterfinals. Last year I predicted 3 of 4 men's quarterfinals correctly and 3 of 4 women's quarterfinals correctly.
Bianca Andreescu (CAN)  vs. Elise Mertens (BEL) . Andreescu is playing in her very first main draw of the US Open and has made it into the quarterfinals. She overpowered Taylor Townsend 6-1 4-6 6-1 in the fourth round, ruthlessly dispatching the tournament's feel-good story with power and resolve. There are only 8 players in the history of the tournament have achieved this feat and some of them have surnames like Williams, Evert and Austin. Brad Gilbert has picked the 15-seed to win the tournament and after watching that match I'm starting to become a Bibi-liever. PREDICTION: Andreescu.
Serena Williams (USA)  vs. Wang Qiang (CHN) . Serena won her fourth round in straight sets but roller her ankle during it. It was a rolled ankle (while holding match point) which led to a colossal collapse in Australia against Pliskova earlier this year (losing from 5-1 up in the 3rd set!) However, now she has had two days to recover and even with 75-80% physical fitness as long as she is mentally tough Serena should be able to win. She's now the only player remaining in the draw who has ever even been to a major final, making this a great opportunity to win another major title, her first as a mother. PREDICTION: Williams.
