World No. 10 Grigor Dimitrov was knocked out of the Stuttgart grass court tournment on Thursday when he was beaten 7-6 (4), 6-3 by Poland’s world 155 Jerzy Janowicz.

The Bulgarian second seed goes the same way as top seed Roger Federer, who was also beaten in the second round on Wednesday, falling 2-6, 7-6 (8), 6-4 to Tommy Haas.

Janowicz will next play the winner of the match between Frenchman Benoît Paire and home player Peter Gojowczyk for a place in the semis.
