MIAMI - World number one Serena Williams and Grand Slam winner Andy Murray were both eliminated out of the ATP and WTA Miami Open on Monday.

Three-time defending champion Williams fell to Russian Svetlana Kuznetsova, seeded 15th, 6-7 (3-7), 6-1, 6-2 in the fourth round and British world number two Murray was stunned by Bulgarian 26th seed Grigor Dimitrov 6-7 (1-7), 6-4, 6-3 in the third round.

The 21-time Grand Slam winner Williams matched her earliest-ever exit from 2000 with a fourth-round departure.

Two-time Grand Slam champion Murray failed in his bid for a third Miami trophy and fourth final in five seasons.

Both players had error-prone matches, each making 55 unforced errors.

Kuznetsova, a two-time Grand Slam champion who lost eight of 10 prior matches to Williams, next faces 30th-seeded compatriot Ekaterina Makarova, who pushed aside Ukraine's 12th-seeded Elina Svitolina 6-1, 6-4.

Also ousted were world number two Agnieszka Radwanska of Poland, upset by 20th-ranked Swiss Timea Bacsinszky 2-6, 6-4, 6-2, as well as Spanish fourth seed Garbine Muguruza, who was defeated 7-6 (8-6), 7-6 (7-4) by 13th seed Victoria Azarenka of Belarus.

In the quarterfinals, Bacsinszky will meet Romanian fifth seed Simona Halep, who eliminated 69th-ranked British wildcard Heather Watson 6-3, 6-4.

Japanese sixth seed Kei Nishikori cruised into the fourth round by routing Ukraine's 27th-seeded Alexandr Dolgopolov 6-2, 6-2 and faces Spanish 17th seed Roberto Bautista Agut for a quarterfinal spot.
