With eight players remaining in the BNP Paribas Open at Indian Wells, the entirety of tennis' Big Four is in contention to win the championship. Rafael Nadal, Roger Federer, Novak Djokovic and Andy Murray have all advanced to the quarterfinals.

Federer moved on to the quarterfinals by easily defeating Jack Sock 6-3, 6-2. The 22-year-old American ranks 58th in the world, and he was no match for the No.2 player on the ATP World Tour. Federer was able to put his opponent away by winning 14 consecutive points in the second set.

Nadal is looking to get back on track as he prepares for the 2015 French Open. On March 1 at the Argentine Open, he won his first title in nearly nine months, and now he’s two victories away from reaching the final. Nadal topped Gilles Simon 6-2, 6-4 on his way to the quarterfinals, looking for his fourth trophy at the event.

"Simon is always a tough opponent but I think I played a positive match," Nadal said, via BBC Sport. "I played a solid match and did not make many mistakes."

The world’s top player had a little more difficult time getting into the final eight, but Djokovic beat John Isner 6-4, 7-6 (5), also looking for his fourth championship. He’ll meet Bernard Tomic in the next round.

Murray is one of the last eight players left, defeating Adrian Mannarino 6-3, 6-3. He avoided a meeting with Kei Nishikori, after Feliciano Lopez upset the fifth-ranked player in the world. The victory was a landmark one for Murray, tying him with Tim Henman for the most career wins by a Brit in the open era with 496.

Murray and Djokoic are heavy favorties to reach the semifinals, with -800 and -1800 odds, respectively, according to Nadal is just a -185 favorite against Milos Raonic, and Federer has been given -260 odds to defeat Tomas Berdych.
