A Varsity Athletics Lottery

I recently found the following news item at the website of Carleton College:

The Carleton College men’s track and field team won seven events and set numerous personal records on Tuesday as the Knights battled cross-town rival St. Olaf College in the annual Rolex Classic at Manitou Field. In keeping with tradition and the congenial relationship between the two squads, the meet’s winner was determined by random selection of a single event after the completion of competition. Lady Luck was on the Oles’ side this year, as the 200-meter dash – an event narrowly won by the hosts – proved to be the decisive event.

I was never very into varsity sports, especially track and field. Does anyone know if this practice is common?

P.S. I haven’t had the chance to review activity on the list for a few weeks. Hope to get back into the swing of things by next week.
