Naperville native Mary DeScenza, who won the short course world title in the 200 butterfly in April, continued her march toward the U.S. Olympic team with her performance at the Santa Clara Grand Prix International meet last weekend.

DeScenza won four silver medals and one gold medal, in you guessed it, the 200-meter butterfly. She talks about her performance in this video.

"It just means that I've been training my little butt off and it just shows that my little workout-practice set has been doing wonders for my butterfly. So it just looks really good going into the trials."

The U.S. Olympic trials begin June 29 in Omaha, Neb.
