Canada's Marco Arop finishes 6th in 3rd career 1500m at Grand Slam of Track
On Saturday, the 26-year-old Arop ran the third 1,500 of his career against "racers" Cole Hocker of the United States, British middle-distance runner Josh Kerr and American Yared Nuguse — the Olympic gold, silver and bronze medallists last Aug. 6 in Paris.
