The Daily Bagel is your dose of the interesting reporting, writing and quipping from around the Internet.
• Photo: Stanislas Wawrinka may have lost a five-set thriller to Novak Djokovic, but he still earned front-page praise back home in Switzerland, along with Justin Bieber (top right).
• USA Today's Doug Robson reports that tennis officials are looking into implementation of a biological passport program to monitor and prevent doping.
The ITF's [Stuart] Miller could not put a dollar figure on a passport program for tennis but said "cost is an issue across all of anti-doping."
Besides funding and informing stakeholders in the sport, Miller said establishing a passport program would require a period of sample gathering and an expert panel to review results.
"It's not just go and collect samples," he said. "We have to get all the pieces together before we're fully operational."
• Incredible story here about Kim Duckhee, a 14-year-old Korean junior, who's deaf.
Lip-reading, then speaking through an interpreter, Lee told reporters at the Australian Open that, in fact, he would rather not even mention his deafness to opponents or officials.
"The one thing that's difficult is the communication with the umpires, both chair umpires and linesmen," he said. "I don't hear the calls, especially the out calls, so sometimes ... just continue. That's kind of difficult but it's nothing special."
• Does Bernard Tomic have a case of the yips? Will Swanton of Fox Sports Australia thinks so.
It is the yips on the two-handed backhand. It is the shot that he lost complete confidence in last year. It should be his bread and butter, as it is for every other pro worth a Babolat contract, but in New York last year, right before everything went to hell in a hand-basket against Andy Roddick, Tomic acknowledged the gremlin.
"It's amazing in practice," Tomic said in New York. "I hit my backhand, like, top four, five in the world when I want to. But all of a sudden I get into a match and I start slicing it and I lose my backhand. I get into this mode where I slice it a lot."
• Speaking of Tomic, his younger sister, Sara, a 14-year-old junior player, won her first match at a Slam over the weekend. She says she'll beat her brother to the No. 1 ranking. Those Tomics sure do like talking, don't they?
