The Daily Bagel is your dose of the interesting reporting, writing and quipping from around the Internet.
• Video: A look back at the best tennis commercial we've seen in a long time: Last year's kid-themed ad for the Stockholm Open.
• Kim Clijsters will be traveling to a few tournaments to help coach her good buddy Kristen Flipkens. With Kim's help, Flipkens has won 22 of her last 24 matches and she beat Sabine Lisicki this week in Luxembourg. How can we miss you if you were never gone, Kim?
"She's not my coach, but she knows how to help me and what I need before and after a match, and she's going to come to some tournaments with me," Flipkens said from Luxembourg. "Her family comes first, so we'll see where it's possible and where it's not, but I'm happy she'll be helping me wherever she can."
• With Marion Bartoli's loss to Sofia Arvidsson in Moscow, the alternates are set for Istanbul, with Sam Stosur going as first alternate and Bartoli as the second. Meanwhile, Raquel Kops-Jones and Abigail Spears kept their Istanbul doubles hopes alive by saving match points in Moscow.
• Richard Pagliaro on why Victoria Azarenka hasn't even reached the top of her game yet.
Martina Hingis summed up the challenge of defending No. 1, saying: "It's always easier being the hunter than the hunted." Azarenka is unique in that she is both hunter and hunted. Vika is world No. 1, but Serena is the world's most dangerous player and has dominated the Minsk-born baseliner, winning 10 of their 11 matches. Complacency is not an option for Azarenka because she knows if she doesn't improve and Serena plays a full schedule, the 31-year-old American can surpass her.
