On the American’s biggest win, and first trip to a Masters 1000 semifinal.

Among the match-ups between modern Grand slam champs, Victoria Azarenka vs. Jelena Ostapenko is one we haven’t had a chance to see often enough. They meet in the first women's semifinal Friday.

After his straight-set thumpings of Brandon Nakashima, Matteo Berrettini and Jannik Sinner, Fritz probably shouldn’t be a 4.5 game underdog against anyone.

“It’s like going from 100 m.p.h. to zero with those three out,” says Hubert Hurkacz’s coach Craig Boynton, about the absence of Roger Federer, Rafael Nadal and Novak Djokovic.

He takes on Jannik Sinner; she faces Victoria Azarenka. And in other fourth-round action, Alexander Zverev meets Gael Monfils.

Andy Murray played well enough to challenge Alexander Zverev in the third round of the BNP Paribas Open Tuesday, but couldn’t match the No. 3 seed in the bread-and-butter aspects of the clash that mattered most.

Zverev called Brooksby “tricky” and “motivated,” but in the end the American’s clever play ran into a top player’s superior all-around power.

The matches are getting real good, real fast, at the BNP Paribas Open.

How can the event improve itself moving forward, after Europe's 14-1 beatdown of Team World?

Team World came close to scoring wins so many times throughout the weekend, but in the end Team Europe—which included six Top 10 players—was just too strong.
