Roger Federer vs. Philipp Kohlschreiber: Score and Reaction from 2015 US Open

Roger Federer cruised past Philipp Kohlschreiber in straight sets (6-3, 6-4, 6-4) Saturday to advance to the fourth round of the 2015 U.S. Open.

The 17-time major champion made a statement by winning the warm-up event in Cincinnati with victories over Andy Murray and Novak Djokovic in the final two rounds. He's clearly carried that strong play into the season's final Grand Slam event.

Federer triumphed five consecutive times in New York starting in 2004. Although he's reached the final just once since that streak ended, he still finds a comfort zone at the USTA Billie Jean King National Tennis Center, as noted by Rachel Cohen of the Associated Press.

"I've always enjoyed conditions here, the balls, the speed of the court, the atmosphere in the arena," Federer said. "It's always worked very well for me. I think this year is another good year. Doing the right things on the court."

He immediately took control of the first set against Kohlschreiber, who he's now beaten in all 10 career meetings. After an easy hold in the opening game, he earned a quick break and held again to make it 3-0 before the veteran German even had a chance to settle in.

Given the way Federer is serving this summer, that probably felt like an insurmountable lead. Sure enough, he held the rest of the way to grab the early advantage. David Law of BT Sport highlighted the Swiss star's success against players from Germany on the sport's biggest stages:

Kohlschreiber started to make more inroads on the second seed's serve in the second set. That included the first break of Federer in more than 70 games dating back to the Wimbledon final against Novak Djokovic. It marked his second long streak of season, via Carl Bialik of FiveThirtyEight:

Federer did get the break right back, however, and regained control of the second set. The No. 29 seed had a couple more looks late in the set to get back on serve, twice getting to 30-30 in return games, but he couldn't capitalize and fell behind two sets to none as a result.

US Open Tennis highlighted one of the key points in the final game of the set:

Kohlschreiber raced out to an early lead in the third with a quick hold and a break. Yet again, however, Federer broke back right away before his opponent could secure the advantage. Andrew Jerell Jones of the Intercept explained how both players were fighting things a bit:

Unsurprisingly, Federer handled the situation better as he eventually scored a late break and then served out the match without any unnecessary drama. He's now swept through his first three opponents without dropping a set.

US Open Tennis showcased the result:

Federer didn't play his best tennis Saturday, but his level of play was still more than enough to move through in straight sets. Being able to get off the court quickly during the first week comes in handy as the matches become more difficult during the business end of the event.

He moves on to the fourth round, where he'll face top-ranked American John Isner. While it's a match he'll be expected to win, the powerful serve of Isner will present some challenges. He does hold a 4-1 edge in their prior meetings, though.

All told, Federer is still one of the tournament's top contenders heading into the second week.
