The 21-year-old Jamaican comfortably beat Kim Collins of Saint Kitts and Nevis, who finished in 10.01 Sunday in Berlin.
Trinidad's Richard Thompson was third in 10.08, with Jamaican Michael Frater — who helped Blake set a world record in the 4x100-metre relay in Daegu, South Korea — finishing fourth.
Blake ran the same 9.82 time at the Weltklasse meet in Zurich on Thursday. The previous meet record was 9.86 held by Maurice Greene and Asafa Powell.

American Ryan Whiting set a meet record of 70 feet, 10 3/4 inches to win the shot put, with teammate Reese Hoffa second at 70- 1/ 4.
