STUTTGART, Germany, June 15 (Reuters) - Second seed Grigor Dimitrov slumped to a 7-6 (4) 6-3 loss to world number 155 Jerzy Janowicz at the Stuttgart Open on Thursday, with the Pole booking a surprise quarter-final spot.
Janowicz made the most of momentary lapses in concentration by Dimitrov, who followed top seed Roger Federer, beaten by Tommy Haas on Wednesday, out of the Wimbledon warmup event.
The Bulgarian world number 12 has now reached only one quarter-final since winning his last of two titles this year back in February.
A sensational backhand down the line - the shot of the match - gave Janowicz the minibreak he needed in the first set tiebreak. Another whipping forehand earned Janowicz, a former world number 14 who has been plagued by injuries in recent seasons, his first two break points on Dimitrov’s serve.
The Bulgarian then sent one of his forehands long to allow his opponent to serve out the match. (Reporting by Karolos Grohmann; editing by Mark Heinrich)
