The Round of 16 is coming on fast at Flushing Meadows, and buzz surrounding both sides of the draw is gaining steam with each passing match.
Thursday's action saw one major upset with Jo-Wilfried Tsonga losing to Martin Klizan. We also watched Venus Williams be eliminated in the day's final match, and we received some shocking news off the court as well.
Competition gets thicker by the day as we get closer and closer to championship time.
Let's take a look at the latest buzz coming out of Flushing Meadows.
Andy Roddick's Swan Song
Roddick announced on Thursday that the U.S. Open will be the final tournament of his career. In a way, his playing days have come full circle.
He became the youngest American to ever reach the No. 1 ATP ranking in 2003 after winning the crown at that year's U.S. Open. That makes Flushing Meadows a fitting conclusion to his underrated career.
Roddick is the last American tennis player to win a Grand Slam, but some fans seem to overlook that. He has had his share of struggles, but Roddick will always be remembered.
Tsonga Sent Packing
Tsonga's loss to Klizan is the first major upset of the tournament. Not only was he the fifth seed, but this is the earliest he's lost in a Grand Slam since 2007.
His 6-4, 1-6, 6-1, 6-3 loss is a tough one to swallow. He seemed to be alright after bouncing back in the second set, but that hope faded as fast as it arrived.
Klizan is only 23 years old, and this is his first taste of Grand Slam success. He was dominant on Thursday, and Tsonga looked like the inexperienced player.
Keep an eye on Klizan as we move forward. You never know what momentum can do for an up-and-comer.
Icons Take Another Step Forward
Serena Williams and Roger Federer both advanced to the third round of play on Thursday with decisive victories.
Williams knocked off Maria Jose Martinez Sanchez 6-2, 6-4. She was extremely efficient and looks well on her way to another deep tournament run.
Federer thrashed Bjorn Phau 6-2, 6-3, 6-2 to advance to the third round. His draw hasn't been difficult, but Nicolas Almagro and Tomas Berdych both stand in his way at some point.
Both are inferior talents compared to Fed-Ex, but they will provide his stiffest challenge yet.
Make sure you tune in to Day 5's action and everything beyond that. The tournament is heating up, and you won't be disappointed.
