The Daily Bagel is your dose of the interesting reporting, writing and quipping from around the Internet.
• Video: Andy Roddick bids farewell to Arthur Ashe Stadium, New York and tennis.
• USA Today's Doug Robson recounts his interactions with Roddick and how it shaped his career as a tennis journalist:
Through the years, he and I had our moments, most recently in February at a tour stop in San Jose, Calif. Sitting in the locker room, I asked a routine question about whether he believed he could win another major. The interview turned testy, but the message was unmistakable: He didn't think he could necessarily compete at the highest level anymore.
• Chuck Culpepper of Sports on Earth on David Ferrer, who "dwells in a happy zone of anonymous fame but non-famous anonymity. He does have fans."
• Buzzfeed looks at the science of grunting:
Grunting: it's an act detrimental to the game, but one that may provide physical, psychological and strategic advantages to its players. It's irritating to some fans and appealing to others. It can be eradicated at developmental academies but is essential to the game's current stars. Men and women both do it, but only women need to stop. Is it any surprise that amidst all these contradictions, the problem is being left at the feet of a vaguely-defined group of future players?
• Andy Murray sits down with TheNew York Times to build the perfect player. He's a big Novak Djokovic fan.
• And not to sell Murray short, here's a breakdown of how he used his chip return to beat Milos Raonic:
But here is where Murray’s particular brand of backcourt genius – his ability to play in a neutral space with complete comfort and control — made Raonic look as if he was dominating the point, until suddenly he wasn’t. It reminds me of what Arthur Ashe used to say about John McEnroe — that you don’t really see the knife until you’ve been nicked a few dozen times and only then do you realize you’ve lost a lot of blood.
• ESPN.com's Kamakshi Tandon says Serena Williams has gone mainstream:
Perhaps her biggest -- and quietest -- concession to prevailing norms has been a switch from natural gut to hybrid strings. Serena and older sister Venus were almost the last players left on tour to still play only with traditional gut -- the just-retired Kim Clijsters was another -- but both Williamses have now made the move to using a combination of gut and polyester strings.
