LONDON — Grigor Dimitrov, considered one of the rising stars in tennis, was eliminated in the second round at Wimbledon on Friday in a five-set, rain-delayed match that lasted more than four hours over two days.

With girlfriend Maria Sharapova watching in the stands on Court 3, the 29th-seeded Bulgarian fell to 55th-ranked Slovenian Grega Zemlja 3-6, 7-6 (4), 3-6, 6-4, 11-9.

Zemlja hit a forehand passing shot on his sixth match point to become the first Slovenian to reach the third round at the All England Club.

Also, Britain's Laura Robson beat Colombia's Mariana Duque-Marino 6-4, 6-1 under the closed roof on Centre Court to reach the third round.

Dimitrov is known as "Baby Fed" for a style that resembles that of Roger Federer. But like Federer, who was stunned in the second round on Tuesday by Sergiy Stakhovsky, Dimitrov was out before the third round.
