Heading into the U.S. Open, Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray have won 36 of the past 38 Grand Slam titles, a stretch dating to the 2005 French Open.
Nowadays, there seems to be a growing sense — or hope, maybe — among the best of the rest on the men's tennis tour that the quartet might be more vulnerable than ever.
Nadal, the 2013 champion at Flushing Meadows, is sidelined by an injured right wrist. Federer is 33 and hasn't won a major championship in more than two years. The No. 1-ranked Djokovic is coming off a triumph at Wimbledon, yes, but he also has a .500 record since. Murray had back surgery and hasn't reached a final anywhere since winning Wimbledon more than a year ago.
Others took note when Stan Wawrinka won the Australian Open in January (Juan Martin del Potro's victory at the 2009 U.S. Open makes him the only other interloper in this era).
"Maybe the gap has closed a little bit. That's in large part due to other players believing. That's the most important thing when you're up against a guy like Rafa, Roger or Novak. You just have to believe that you can beat those guys," said John Isner, the only seeded American man in New York at No. 13.
Here are other things to watch at the U.S. Open, the hard-court tournament in New York that begins Monday and ends Sept. 8:
NEW KIDS: If there is going to be a first-time men's major champion, two popular picks are Milos Raonic of Canada and Grigor Dimitrov of Bulgaria. Each is 23; each made his Slam semifinal debut at Wimbledon. While Dimitrov has never won a U.S. Open match, Raonic reached the fourth round the past two years. All six of Raonic's titles came on hard courts, and some opponents consider his serve the sport's best. So does he. "I have a lot of belief in my serve," Raonic said. "I know how hard it is to break me and how well I can take care of my serve against anybody."
SERENA'S MAJOR CONCERN: Serena Williams could become the first woman in nearly 40 years to win three consecutive U.S. Opens, but she has not been past the fourth round at a major in 2014. After a third-round loss in singles at Wimbledon, Williams made a bizarre exit from doubles, whiffing on practice strokes, having trouble grabbing tennis balls, and quitting after four double-faults in a row.
