During Saturday's Minnesota Twins vs. Baltimore Orioles game, a beautiful butterfly was seen flying around the Twins' manager Rocco Baldelli.

The field was being used as part of the Big Butterfly Count, a national survey backed by Sir David in which the public is being asked to spot and record 17 species of butterfly.

Regan Smith won the 100 butterfly at the TYR Pro Series in San Antonio, and could be a factor in the event at the Olympic Trials.
