There's an interesting article on Fangraphs speculating that clubs will keep a Billy Hamilton speedster on their rosters for as long as possible to have available for extra inning situations. The idea being that you bat him last at the end of the ninth so worst case, he would start the 10th on 2nd.

Had the identical thought about Billy Hamilton when this came out. So LOOGYs bad, hitless speedsters and runner checks good
