Super silver for rising star Gregan
The 21-year-old Clonliffe Harrier, who also finished second in his semi-final on Thursday, repeated that performance when he split the two British competitors, Nigel Levine and Luke Lennon-Ford, in an enthralling final.
His time, 46.12 secs, is a new lifetime best and leads the list of Irish performers for 2011 ahead of Brian Murphy (UCC) who ran 46.41 in Brussels and national record holder, David Gillick, whose best for the year is 46.64 which he ran in New York.
