The Daily Bagel is your dose of the interesting reporting, writing and quipping from around the Internet.
• Video: There have been seven Masters 1000 events this year. Three men have won all of them. One man has won five of them.
• Can Rafael Nadal break the record for most Grand Slams in the Open Era? Jeff Sackman at Tennis Abstract says it's all about the French Open:
Before diving into the numbers, there’s the argument I’ve always used in favor of Nadal piling up plenty of Slams. They hold the French Open every year. Each clay season that Rafa is healthy and playing like Rafa, he’s probably going to add at least one title to the list.
He’ll be just shy of his 28th birthday at the 2014 French Open, meaning that if he keeps winning every match he plays at Roland Garros, he’ll have four more French Open titles right about the time he turns 31, at the 2017 French Open. With what seems like half the tour playing quality tennis at age 30, and with Rafa aggressively skipping events this year, it’s easy to imagine him winning four more Slams on clay.
Or seven more. As long as he can stay healthy enough to play on his favorite surface, one gets the sense it’s up to him.
• Kamakshi Tandon looks at Roger Federer's age not via his birth certificate, but based on the number of matches he's played.
Although Federer came into the US Open as one of 11 men in the draw aged 32 or older, he was by far the oldest in terms of matches at the pro level. The 17-time Grand Slam champ had played 1,119 ATP matches in his career coming into the tournament (winning 910), and a total of 1,177 on the tour and minor leagues.
Meanwhile, [Tommy] Haas -- the oldest player in the draw and about 3 years and 4 months older than Federer -- stood at 883 matches, or about three-quarters of Federer's total. Michael Russell, also 35, came in at 802 matches, most of those at the minor league level.
Lleyton Hewitt is another 32-year-old former No. 1 still playing on tour, but Hewitt peaked and declined much earlier in his career, and has also had much more injury trouble than Federer. He has played 862 matches.
