• Federer and Jordan collaborated on Federer's shoes for the U.S. Open that he wore in Tuesday night's match, and he said afterwards that the opportunity to meet the basketball legend was surreal. "Meeting him yesterday for the first time was a big deal for me," Federer said. "It was a special sort of last 24 hour plus."

• It must have been a thrill for Federer to get a chance to hit his famous trick-shot 'tweener with Jordan in the crowd, even if it didn't count. Even better that he tagged Matosevic in the butt with it:

• Louisa Thomas for Grantland contrasts the minds and styles of Simona Halep and Eugenie Bouchard. And if Ernests Gulbis is more your style they've got you covered there too. On Gulbis: 

So he took me by surprise when he explained early in our discussion that he hates press conferences. “I hit the ball good, I won, sorry for the other guy, blah, blah, blah, the same bullshit,” he said. It’s odd, he added, that tennis players and other athletes are forced to give daily interviews. “How often do you see other professionals, lawyers or musicians, give an interview? Let’s say you’re a guitar fan. Well, Jimmy Page may give a long interview every five years, but there’s not really much new for him to say. But we’re asked to do it every day. ‘Today was a special day, I felt incredibly different than the day before’ — it doesn’t happen like that. It’s basically the same. I can give two sentences if I win, two other sentences if I lose, and you can use it all year long.”
