Novak Djokovic vs. Andreas Haider-Maurer: Score and Reaction from 2015 US Open

Novak Djokovic waltzed past Joao Souza in his opening-round match at the 2015 U.S. Open, and he turned in a repeat performance Wednesday night as he squashed second-round opponent Andreas Haider-Maurer at Arthur Ashe Stadium in New York.        

The world's top-ranked player dispatched Haider-Maurer 6-4, 6-1, 6-2 to set up a third-round date with Italian Andreas Seppi, who downed Teymuraz Gabashvili in four sets on Wednesday.

Djokovic's evening was paced by efficiency on serve, which wasn't exactly a surprise after he lost just three points on serve against Souza, according to ESPNTennis on Twitter. 

In the straight-sets victory, Djokovic won 83 percent of his first-serve points and 77 percent of his second-serve points. He also won 48 percent of his receiving points—29 percent better than Haider-Maurer. 

Haider-Maurer stayed competitive early in the first set thanks to a blistering serve that topped out at 137 miles per hour, but a late break from Djokovic eased concerns regarding any sort of early letdown. 

US Open Tennis on Twitter provided a look at the final point of the first set: 

And while it took Djokovic 10 games to score his first break point in the opening frame, he grabbed his second of the evening on Haider-Maurer's first service game of the second set.  

From there on out it was smooth sailing for the world No. 1. Djokovic proceeded to win five straight games, as his powerful groundstrokes proved to be too much for his 28-year-old opponent.  

"No one is better at wearing down opponents than Djokovic, according to Brad Gilbert, who likened the world No. 1's game to [Andre] Agassi," ESPN.com's Greg Garber wrote. "Like the American, Djokovic plays a calculated, controlled offensive game by hitting the ball heavy to the corners, establishing court position and pulling the trigger earlier." 

Haider-Maurer's fate was all but sealed an hour into the lopsided match, as Djokovic took a commanding two-set lead, per US Open Tennis on Twitter:

The Serb won 73 percent of his first-serve points in the second stanza, but his 85 percent success rate on second-serve points proved to be the difference. While Djokovic had no problem controlling pace of play on second serves, Haider-Maurer won just three of his 12 second-serve points during that stretch. 

Djokovic closed out his evening by winning 14 of the match's final 17 games.  

The 2015 Australian Open and Wimbledon champion wasn't at his absolute best Wednesday night, but his play over the course of the year suggests he's primed for big things, per ESPNTennis on Twitter:

"I think this season, results-wise [is] pretty close to 2011," Djokovic said, according to Sports Illustrated's Stanley Kay. "What I achieved in 2011 is hard to repeat, so this season is definitely just behind that one."

Four years removed from capturing three major championships in Melbourne, London and New York, Djokovic is in line for a historic repeat performance.
