Madrid Open: Dimitrov, Kyrgios advance as Sock & Monfils exit

Grigor Dimitrov and Nick Kyrgios were among the first-round winners at the Madrid Open as Jack Sock bowed out.

Dimitrov, the 12th seed, was tested before getting past German Philipp Kohlschreiber 7-6 (9-7) 6-4 on Monday.

The Bulgarian advanced in one hour, 48 minutes on what was a relatively good day for the seeds in Spain.

Despite battling a groin injury, Kyrgios claimed a 7-6 (7-1) 6-4 win over Marcos Baghdatis.

The Australian, a quarter-finalist at the ATP 1000 event last year, sent down 14 aces and did not face a break point.

Only two seeds departed on the clay, with Sock and Gael Monfils exiting.

Sock, who held an impressive 20-6 win-loss record this year heading into the event, was a shock 6-4 0-6 7-6 (7-4) loser to Nicolas Mahut.

In a rollercoaster all-French clash, Monfils went down to Gilles Simon 0-6 6-0 7-6 (7-0).

Czech 11th seed and 2012 runner-up Tomas Berdych encountered few problems on his way to a 6-4 6-4 win over qualifier Denis Istomin.

Jo-Wilfried Tsonga needed almost three hours to overcome Andrey Kuznetsov 7-6 (7-5) 6-7 (5-7) 7-5.

Meanwhile, Feliciano Lopez was too good for Ernesto Escobedo 6-4 6-4, David Ferrer beat Mikhail Kukushkin 2-6 7-6 (7-1) 6-4 and Florian Mayer claimed a 7-5 7-5 win over Marcel Granollers.

Pablo Cuevas battled past Thomaz Bellucci 7-6 (7-2) 4-6 7-6 (8-6), Jared Donaldson recorded a 7-5 6-3 win against Adrian Mannarino and Robin Haase beat Daniel Evans 7-5 6-2.
