Here are the storylines to watch on Day 11 of the U.S. Open. ESPN2 begins its coverage at 12 p.m and ESPN picks up the evening session at 8 p.m. Click here for the order of play.

Novak Djokovic and Andy Murray on a collision course: The Rafael Nadal-Roger Federer quarterfinal never materialized thanks to Tommy Robredo's fourth-round upset of Federer, meaning the men's side of the draw has been lacking in blockbuster, must-see matches. That will change if Djokovic and Murray take care of business against their respective quarterfinal opponents and meet in the semifinals in a rematch of last year's final, not to mention a rematch of two of the three Grand Slam finals this year, which the two have split.

Murray gets the day session slot as he takes on No. 10 Stanislas Wawrinka (second day match, Arthur Ashe Stadium). Murray leads the head-to-head 8-5 and has generally gotten the better of Wawrinka when they've played on the quicker courts. But Wawrinka handed Murray one of his worst losses at a Slam in New York in 2010, shocking him a 6-7 (3), 7-6 (4), 6-3, 6-3 in the third round. Wawrinka came so close to beating Djokovic at the Australian Open this year, and his win over Tomas Berdych in the fourth round was clean and decisive.

Here's a look back at that clash against Djokovic, which remains the best match of the year:

Much has been made about how Murray doesn't seem to be playing his best tennis, fighting through the heavy conditions to get past Florian Mayer in the third round and dropping a set to Denis Istomin in the fourth round. But that's just how Murray's Slam runs usually go. When he won the title last year, he was pushed to four tight sets against Feliciano Lopez in the third round and then dropped a set to Marin Cilic and Tomas Berdych before the final.

Djokovic will close the night session against Mikhail Youzhny (8 p.m., Arthur Ashe Stadium). Djokovic's fourth-round win was more like a hit-and-giggle, as he steamrolled an exhausted Marcel Granollers 6-3, 6-0, 6-0. Youzhny, meanwhile, needed five sets to defeat Lleyton Hewitt. I can't see Djokovic losing this one. He's looked incredibly sharp.

The Bryans face their biggest test so far: A they go for the calendar year Grand Slam, Bob and Mike Bryan face their toughest test yet against the fourth-seeded Leander Paes and Radek Stepanek in the semifinals (first match, Arthur Ashe Stadium). The teams have split their Slam meetings, with Paes and Stepanek beating the Bryans in the 2012 Australian Open final, while the Bryans started their Slam streak by beating them in last year's U.S. Open final. Serena and Venus Williams get test, too: Serena and Venus may be the favorites in the women's doubles, but it's still their quarterfinal opponents, Sara Errani and Roberta Vinci, who are the top seeds and defending champions (second match, Louis Armstrong Stadium). Errani and Vinci knocked the Williamses out of the Australian Open this year.
