The U.S. Open continued on Tuesday, and competition wasn't negatively impacted by rain like we saw on Monday.
Tuesday's action was mostly on point with what you would expect from early-round action, but we did see a handful of minor upsets from both the men's and women's sides of the draw.
Let's take a look at some Day 2 scores and highlight the day's best moments.
Here is the full list of scores from Tuesday's action, but I'll highlight some of the day's biggest scores:
Agnieszka Radwanska (2) defeated Nina Bratchikova 6-1, 6-1
Andy Roddick (20) defeated Rhyne Williams 6-3, 6-4, 6-4
Venus Williams defeated Bethanie Mattek-Sands 6-3, 6-1
Tomas Berdych (6) defeated David Goffin 7-5, 6-3, 6-3
Jo-Wilfried Tsonga defeated Karol Beck 6-3, 6-1, 7-6 (2)
Guillermo Garcia-Lopez defeated Juan Monaco (10) 3-6, 1-6, 6-4, 7-6 (6), 7-6 (3)
Angelique Kerber defeated Anne Keothavong 6-2, 6-0
Novak Djokovic (2) defeated Paolo Lorenzi 6-1, 6-0, 6-1
Serena Williams (4) defeated Coco Vandeweghe 6-1, 6-1
Kiki Bertens defeated Christina McHale (21) 4-6, 6-4, 6-3
Garcia-Lopez's win over Monaco was not only the best match of the day, but it was also the biggest upset.
After losing the first two sets, he managed to rally for three-straight victories. Monaco wasn't a favorite to win this tournament, but he did make it to the fourth round in last year's Open.
Keep an eye on Garcia-Lopez. This is the fifth-straight year that he's advanced to the second round, and he's due for a breakthrough.
This could be it if he can continue the momentum from Tuesday's upset.
With his victory over Lorenzi on Tuesday, Djokovic didn't show any hangover from his disappointment in the London Olympics.
A straight-set victory was easy enough to anticipate, but it's still good to see Djoker on his A-game so far in Flushing Meadows.
Djokovic will try to defend his 2011 title this year, and beating Lorenzi was the first step. His groundstrokes were on point, and he looked like his old self.
He's one of the world's best hard-court players, and he left no doubt about that on Tuesday. His path got easier the second we found out that Rafael Nadal was out of this tournament, but if he keeps playing like this, it won't matter either way.
Serena Williams Continues Her Run
Williams defeated Vandeweghe in easy fashion to earn a first-round victory at Flushing Meadows Tuesday night.
A U.S. Open victory would put a perfect cap on an incredible summer for Williams. She won Wimbledon and followed that up with a gold-medal victory in London.
Williams' powerful game is tough to stop when she's on, and she was on Tuesday. She berated Vandeweghe with winner after winner, and her groundstrokes kept her opponent moving from side to side.
Look for Williams to continue her run deep into U.S. Open action. She's been on a mission all summer, and a loss before the finals seems inconceivable at this point.
