Somehow, it seemed so easy for so many people to write off Roger Federer.
He was past his 30th birthday, they would point out.
About 2½ years went by without any additions to his Grand Slam trophy case, the thinking went.
First Rafael Nadal, then Novak Djokovic, overtook Federer in the rankings and as the man to beat at major tournament after major tournament.
Well, look at the guy now. Wimbledon champion, once again, stretching his record total to 17 Grand Slam championships. Ranked No. 1, once again. And heading into todays start of the U.S. Open the favorite to reach the final, once again.
Im out of the business of predicting Federer anymore, said Andre Agassi, a two-time U.S. Open champion and runner-up to Federer in 2005. Hes continually surprised me with his achievements; he no longer surprises me. I think he has a lot more tennis in him. He looked as comfortable as Ive ever seen him on the tennis court in England. He maybe needs one or two things to fall for him to knock down a few more (Grand Slam titles) at this stage of his career, but hes certainly as capable of it as anybody Ive ever seen.
Federers pursuit of a sixth U.S. Open title at age 31 certainly will be among the main angles to keep track of on the hard courts of Flushing Meadows.
Other stories to watch include:
Djokovics bid for a second consecutive championship in New York and fifth major title in two years.
Andy Murrays attempt to follow up his Olympic gold medal with Britains first Grand Slam mens singles title since 1936.
Andy Roddicks hope for one more deep run in front of the home fans.
Four-time major champion Kim Clijsters farewell to tennis in what she says is the last tournament of her career.
Venus Williams return to the U.S. Open a year after withdrawing from the tournament and revealing she was diagnosed with an autoimmune disease.
Serena Williams try for her 15th major trophy and, of course, what sort of interaction she might have with on-court officials after a foot-fault tirade in the 2009 semifinals, then a youre just unattractive inside monologue in the 2011 final.
My mind frame this year is that something is going to happen, for sure, because something always happens to me at the Open, whether its a horrendous line call thats 2 feet in, or whether its a grunt and I get a point penalized, or a foot-fault when I actually dont foot-fault. Im prepared for something to happen, said the younger Williams sister, a three-time champion in New York whose serve was dominant recently en route to her fifth title at Wimbledon and two gold medals at the Olympics.
Another key question is what sort of effect there will be from the short turnaround and shift to hard courts after the grass-court London Games.
Theres no doubt about it: This is not an ideal preparation, said Federer, routed 6-2, 6-1, 6-4 by Murray in the Olympic final Aug. 5, less than a month after beating him in four sets on the same court in the Wimbledon final.
Its not impossible, but its just very hard on the body and mind to travel halfway around the world, go on a different surface, Federer said.
In the past, you would take maybe a few weeks off for a top player, then prepare for three brutal weeks on hard courts, then come over here wanting to fire (on) all cylinders. This year, its different.
He once won 40 matches in a row at the U.S. Open, a streak that ended with a five-set loss to Juan Martin del Potro in the 2009 final. That was followed by semifinal setbacks against Djokovic each of the last two years, including what Federer calls that brutal match with Novak in 2011, when Federer took the first two sets, then held two match points, but couldnt close the deal.
On the first match point, Djokovic smacked a gutsy forehand return winner that barely landed on a line and drew something of a rebuke from Federer afterward.
I never played that way, Federer said at the time. I believe in the hard-works-going-to-pay-off kind of thing because early on, maybe I didnt always work at my hardest. So for me, this is very hard to understand how (he could) play a shot like that on match point.
Djokovic went on to victory in the final against Nadal, the 2010 U.S. Open champion and 11-time major winner who currently is out with knee problems and wont be in New York. That was part of a stretch in which the Serb and the Spaniard split up nine Grand Slam trophies in a row, shutting out Federer and leaving him stuck on No. 16 for more than two full seasons.
Given how rare it is for a man past 30 to remain in the upper echelon of tennis a not-quite-31 Federer was the oldest Wimbledon champion since Arthur Ashe in 1975 and the ascension of a couple of rivals in their mid-20s, there were plenty of whispers that the Swiss superstar might be done.
A man who reached a record 10 consecutive major finals from 2005-07, then another eight in a row from 2008-10, suddenly was losing the occasional Grand Slam gasp! quarterfinal.
What, after all, was left to motivate him?
What could drive him to keep up?
Djokovic and Nadal, to name two, never doubted Federer would reassert himself.
He was always there, Djokovic said. Last couple years, he didnt win a major, but he was in a couple of finals and always semifinals. Hes always playing close matches against whoever.
Federer beat Djokovic in the Wimbledon semifinals, then topped Murray for triumph No. 7 at the All England Club, tying Pete Sampras and William Renshaw (who played in the 1880s) for the most in history. That also allowed Federer to return to No. 1 and, a week later, break Sampras career record for most time atop the ATP rankings.
Continuing what he termed a magical summer for me, Federer earned his first individual Olympic medal. Then he showed he still can turn up big on hard courts, winning a record-equaling 21st career Masters title last weekend, holding serve throughout the tournament and beating Djokovic in the final.
Federer, Djokovic and Nadal have combined to win 29 of the last 30 Grand Slam titles (del Potro is the only interloper in that span, which began in 2005).
Murray has been on the outside looking in, but there are suspicions that his success at the Olympics could be a harbinger of whats to come.
Come the U.S. Open, I hope this will have given me the confidence to go there and believe in myself a bit more than I have in the past and give myself a shot at winning there, Murray said at the Olympic Games.
It also means he already owns one of this seasons top five prizes; Djokovic won the Australian Open in January, and Nadal won the French Open in June before Federer re-emerged at Wimbledon.
It is interesting, obviously, that three different guys have won three different majors this year, plus Andy the gold, Federer said. It definitely sets a great tone for the U.S. Open, theres no doubt about that.
With Nadal sidelined, and Murray still waiting to win a major final, Federer and Djokovic appear set to take center stage at the U.S. Open.
At the very least, Federer firmly is back at the forefront.
Putting my pure fan hat on: Hes one of the greatest of all time. Its not only the quality of his play; its how he represents our sport on the court and off the court, WTA Chairman and chief executive officer Stacey Allaster said. Hes just one of those athletes that well all look back and say how blessed we were to have been able to see him perform at the highest level of our sport that weve ever seen and for such a long period of time.
