The 2012 U.S. Open enters its fourth round on Monday, with some of the game's brightest stars taking center stage.

Roger Federer will be the focus of many people's attention when he takes on No. 24 Mardy Fish. Federer has had a revival of sorts to his career this year and is trying to cap it off with another major championship.

Third-ranked Andy Murray also has a tough match against a quality opponent, pitted against 15th-ranked Milos Raonic. Murray is still riding a wave of momentum after winning a Gold Medal in his home country this summer.

Serena Williams is also back on the court, looking to advance to the quarterfinals in search of her fourth U.S. Open title. On Labor Day, Williams has the task of defeated unranked Andrea Hlavackova.

In what many feel will be a great match, No. 6 Jacqueline Kerber and 10th-ranked Sara Errani will duel for the chance to continue forward.
