Good Night!

Roger Federer Caroline Wozniacki both made quick work of their opponents during yesterday's night session. Federer won a straightforward match in three sets against Roberto Bautista Agut while Wozniacki absolutely steamrolled Sara Errani.

What's Gotten Into Gael?

Gael Monfils is usually more focused on making highlight reel shots than he is on winning matches, but he's looked laser-focused throughout most of the tournament. For the most part, he delivered another solid performance yesterday against Grigor Dimitrov, though the wheels looked like they were ready to fall off in the latter stages of the second set. Monfils let a lead slip away, but he eventually fought off his disquiet enough to grab the second set and the match. If you're counting, that's four straight set wins in a row for Monfils.

That's... Gonna Leave A Mark

During warmups, Gilles Simon hit a practice serve that smacked an unaware ballgirl in the face, leaving her understandably in tears. A horrified-looking Simon walked over to check on the girl as she sheltered behind the umpire's chair.

On-Court Coaching

Over the weekend, Sabine Lisicki was scolded by the chair umpire for a possible coaching violation. Yesterday, Switzerland's Belinda Bencic also heard from the umpire about a possible coaching violation. If there was a coaching infraction, it didn't make much of a difference as Bencic was blitzed 6-2, 6-1 by Peng Shuai. The win moves Peng Shuai on to her first Grand Slam singles semifinal.

Doubles Doom?

With their doubles loss yesterday, Venus and Serena have failed to reach the finals in the last eight doubles matches they've contested. It's the longest spell without reaching a final in their doubles career together.

Re-fined Fognini

Tennis wild man Fabio Fognini may finally be grinding down some of his rough edges (though I doubt it). After getting slapped with a $27,500 fine—the largest on-site fine in Slam history—at Wimbledon, Fog only managed a comparatively meager $2,000 fine at the US Open. According to Ben Rothenberg, Fog's tied for third with Jack Sock, Steve Johnson, Andrea Petkovic, Coco Vandeweghe, and Tatsuma Ito. Adrian Mannarino leads the list with $6,000, followed by Nick Kyrgios with $5,000.
