American sprinter Tyson Gay broke a 44-year-old world mark for the 200 meters on a straight track.
Gay ran 19.41 seconds into a slight headwind yesterday on a specially constructed track in Manchester, shaving 0.09 off Tommie Smith's mark set in May 1966 at San Jose, California.
Smith was at the Great City Games to watch the 27-year-old Gay beat his time, which isn't an official world record because athletic's governing body only recognizes 200s run around a curve.
