Fifth-seeded Juan Martin del Potro of Argentina crashed out of the Miami ATP Masters on Friday, falling 7-6 (7/5), 6-1 to 89th-ranked German Tobias Kamke in a second-round match disrupted by rain.
Del Potro had just dropped the first-set tiebreaker when the match was halted by rain, the break lasting almost three hours.
The delay clearly did no favors to the world No. 7 from Argentina, who had stormed to the final of the Indian Wells Masters last week with wins over world No. 3 Andy Murray and world No. 1 Novak Djokovic.
His semi-final win over Djokovic in the California desert had ended the Serbian star's match winning streak at 22, but del Potro then fell to Rafael Nadal in the final.
Kamke, 26, next faces Austrian Jurgen Melzer, who beat Spain's Marcel Granollers 6-3, 6-4.
