The Daily Bagel is your dose of the interesting reporting, writing and quipping from around the Internet.
• Video: This incident got lost in the shuffle during Wimbledon, but that doesn't make it any less baffling. Alex Bogomolov got fed up with the umpire and promptly, yet calmly, retired from his match against Bradley Klahn during the Winnetka Challenger. He has some NSFW words for the umpire as he leaves the court, too.
• Caroline Wozniacki took to Twitter to settle rumors stemming from a Danish report that she hired Thomas Hogstedt as her new coach:
• Martina Hingis has come out of retirement to play doubles with Daniela Hantuchova at the Southern California Open in Carlsbad, Calif.
• Marion Bartoli and Jo-Wilfried Tsonga are the first team confirmed for Hopman Cup.
• Donald Young lost in the first round of a $50,000 ATP Challenger in Binghamton, N.Y., after serving for the match at 5-3 in the second set and losing eight straight games.
• Fun piece from Bruce Jenkins on fielding a dream doubles tournament to challenge Mike and Bob Bryan.
• Andy Murray says he won't sign on to the new winter Asian tennis league if it interferes with his training block.
"What I agreed to is playing three nights in one place," he says. "So I'm not travelling across the whole of Asia in the space of a week. A lot of others play loads of exhibitions in December. I've never really done that. But, if I could be in one place for a week and take my guys there and train properly, it could work well. If I tried it and I didn't think it was working, I'm not going back. That's the reality. My training blocks are really important and I won't let anything get in the way of that.
• Peter Bodo on Serena Williams' and Roger Federer's surprising clay-court appearances this week.
Federer, the top seed in the Hamburg ATP 500, lost in the second round at Wimbledon to Sergiy Stakhovsky. In his press conference immediately after that match, he said the first thing he would do is “not panic.” Yet in language that curiously distanced himself from, well, himself, Federer said to reporters in Hamburg: “I think this decision was made very quickly the day after Wimbledon.”• Non-tennis: How Twitter killed Zimmerman Trial Juror B37's book deal.
Panic? Not exactly. It was like recognition that his grand plan for this year, and perhaps the immediately ensuing ones, needed some tweaking. Federer has really pared down his schedule this year, but in doing so he’s put a lot of pressure on himself to go deep into tournaments when he does play.
The second round loss at Wimbledon was unexpected, and particularly damaging to Federer’s ranking. Defending 2,000 points, he had to settle for 45, and promptly dropped from No. 3 to No. 5 in the rankings. That underscored the dilemma Federer faces as he seeks to play less, but still maintain his high ranking.
In entering Hamburg, Federer was going back to a well from which he drew up sweet wine plenty of times. He’s won the event four times, back when it was a Masters 1000 event and a considerably more difficult task. He’s had some terrific wins there, including his first-ever on clay over Rafael Nadal, and he’s likely to enjoy the change in conditions, from somber, cold and wet (when the tournament was part of the run-up to Roland Garros) to hot, dry and quick. And if he wins the event, the 500 ranking points will be considerably more than he would have earned with a quarterfinal showing at Wimbledon (360 points), if not as much as a semi (720).
