BOSTON — Japan’s Hiroyuki Yamamoto sprinted to an early lead and cruised to a win in the Boston Marathon men’s wheelchair race.

Yamamoto’s won Monday’s race in a time of 1 hour, 25 minutes and 33 seconds, well ahead of runner up and nine-time champion, Ernst Van Dyk, of South Africa.

Yamamoto’s countryman, Kota Hokinoue, finished third.

Yamamoto took control of the race early, grabbing a 4-second lead about 3 miles in, increasing it to 17 seconds by the halfway point and expanding it from there.

The win was well off the world record time of 1:18.25, set by Canada’s Joshua Cassidy at last year’s Boston Marathon.
