• Video: Here's an awkward promotional ad for Bacardi starring Rafael Nadal. I don't understand the need to break the fourth wall a la The Office.
• Caroline Wozniacki scored a nice win in Doha on Thursday, beating the streaking Mona Barthel 7-6 (6), 6-3 in windy conditions. Tennis.com's Steve Tignor noted Wozniacki's -- and her father's -- feistiness:
Caroline, who had won their previous two meetings in straight sets and didn’t want that record to change, was as feisty as ever today. She argued every close call that went against her. She threw her hands in the air as she walked toward the chair umpire. She bashed the net with her racquet. In the second set, her even feistier father, Piotr, got in on the action by arguing her case with the ump from the stands. He was finally asked to leave by security, but he wouldn't budge.
• UPDATE: Here's video of the incredible incident, with Piotr screaming at umpire Julie Kjendlie from the stands and getting a talking to from a tournament official. It's unclear if he was asked to leave but I think he should get either a fine or a match-ban for that kind of behavior. This isn't juniors and he basically bullied the umpire into replaying the point. There was no way Wozniacki had a play on that ball. (h/t @amyfetherolf)
• Roger Federer says he didn't watch any of Rafael Nadal's matches from Chile last week, but the Swiss is happy to see his rival back.
“I saw a few pictures: He looked good—[smiling] nice shirt. Still a left-hander. I was hoping he came back as a right hander: He didn’t!”
• Matt Cronin catches up with Donald Young at the SAP Open in San Jose, Calif.
“I put 2012 out of my mind. I already won more matches this year than I’ve won all of last year,” said the now No. 202 ranked Young, who won two rounds of qualies in Brisbane, the Australian Open and then three in San Jose. “I can’t really tell you what happened. You start losing and it spirals down and I won a few matches at the end of the year, but it wasn’t enough. It was awful and I choose not think about cause when I do, a lot of bad memories come back.”
• In this week's Report Card, I gave Agnieszka Radwanska a C-minus for giving one of the coldest press conferences I've ever seen. It turns out she was unhappy with the Israeli crowd during Poland's Fed Cup tie against the home nation, though she didn't provide any detail about what was said.
• The relationship between Serena Williams and Sloane Stephens, as reported by the media during the Australian Open, went from "Hey!" to "Hero" pretty quickly. • Non-tennis: Great read by espnW's Kate Fagan on sexism in sports.
