In the process, Federer also became the first player since 1976 to win the title without dropping a set, per ATP Media Info:
On this form, the 35-year-old has to be considered a major contender to dominate at the upcoming U.S. Open in August at Flushing Meadows, New York.
Federer has served notice he is still the dominant player in the sport after the way he dismantled Cilic. He attacked from the off on Centre Court and kept the Croatian's powerful service game in check.
It helped that the Federer serve is also deadly, with the Swiss often winning points on second serve, per Christopher Clarey of the New York Times:
Federer claimed the first set at a canter and soon made it two in a row. As ATP Media Info detailed, it was rare to see a final move this quickly at the All-England Club:
Up two sets and a break in the third, Federer soon wore down Cilic and served out to become the most successful men's player in Wimbledon history.
The speed with which he worked over Cilic was typical of the way Federer has approached matches in the English capital this year. Even at 35, the veteran still knows how to set and control a quick pace.
He has a powerful, subtle and varied service game to thank for this trait. Clarey pointed out how efficient and unbreakable Federer was on serve in the final:
Serving prowess is a requirement for winners in New York, where the harder courts benefit those players who prefer a speed game. Federer has proved his serve-and-volley style remains as formidable as ever, so he is naturally a strong contender to win at Flushing Meadows.
The same conditions on court can favour other prominent players in the men's bracket, such as Novak Djokovic, Andy Murray and Rafael Nadal, all of whom will be keen to make amends for coming up short to Federer at Wimbledon.
Murray was put out by Sam Querrey in London. The big-serving American is something of a dark horse headed to the Open.
Even so, it's tough to see anyone in the bracket beating an in-form Federer in New York, not even Cilic, who dismantled the Swiss in straight sets at Flushing Meadows back in 2014.
Winning in New York used to be routine for Federer, who once won five U.S. Open titles in a row. However, his last came in 2008.
Yet one more triumph at Wimbledon has proved the sport's best player is refreshed and as determined as he's ever been to stay on top. Peak form and relentless motivation can add up to a sixth title at Flushing Meadows for Federer.
