Tomoki Sato captured his second gold medal of the World Para Athletics Championships by winning the men's 400 meter T52 wheelchair race in a meet record of 56.78 seconds on Tuesday.
Sato added to the gold medal he won in the 1,500 meters on Sunday, when he came from behind in the last 50 meters to beat Rio Paralympic champion Raymond Martin of the United States. Hirokazu Ueyonabaru was third.
"I dug in desperately," said Sato, who won two silver medals at the Rio Paralympics last summer, finishing behind Martin in both the 1,500 and 400 races.
