The rider with the independent LCR Honda team dealt best with the wet track that was slowly drying out after rain earlier in the day to cover 22 laps of the 5.403-kilometer (3.357-mile) Brno circuit in 47 minutes and 44.290 seconds.
“I’m really, really pleased for my team,” Crutchlow said. “We worked hard for this.”
After starting from 10th position on the grid, Crutchlow gradually moved ahead to take the lead with seven laps to go. Unlike most riders who started on soft tyres, Crutchlow opted for hard ones and that strategy paid off.
“I took the gamble,” he said. “We did the best job we could today.”
