Kim Collins rolls back years with Pan-Am 100m record

GUADALAJARA, Mexico, (Reuters) – Former world 100  metres champion Kim Collins rolled back the years to break the  28-year-old Pan-American Games record yesterday.
The 35-year-old from St Kitts and Nevis, the 2003 world  champion, clocked 10 seconds flat in the semi-finals for a time  two hundredths slower than his personal best.
Cuba’s Yarisley Silva dethroned women’s pole vault holder  Fabiana Murer in an absorbing duel won with a personal best 4.75  metres to smash her Brazilian rival’s Games record of 4.60.
The 24-year-old Silva cleared the bar first time at every  height until it was raised to 4.80.
