Josh Kerr won the 5th Avenue Mile race in New York for the second straight year and smashed the 43-year-old course record.
The Scot came home in three minutes 44.3 seconds, more than three seconds faster than the previous best set by Sydney Maree in 1981.
Just three days after finishing fifth in the Zurich Diamond League meeting, the world 1500m champion and Olympic silver medallist finished ahead of American Josh Hoey and Kenyan Amon Kemboi.
Kerr, 26, now holds two of the three fastest times in the race’s history.
His fellow Scot Neil Gourley finished 16th.
