Four United States Masters Swimming national records fell at the Illinois Masters Short-Course State Championships the weekend of April 22.

80-year-old Thomas Maine of Saluki Masters in Carbondale broke his own national record in the 200-yard butterfly touching in 3:25.55. This is Maines third time breaking the record in 2006. His previous record was 3:29.17.

36-year-old Vlad Pyshnenko, swimming unattatched, swam to an amazing 0:45.32 in the 100-yard freestyle beating Ron Karnaugh's previous record of 0:46.04.

A short time later four extremely fast women representing Team Illinois Masters swam to a USMS National Record in the 35+ Medley Relay. Andrea Block, Jennifer Ridge, Liz Dillmann and Nadine Day (pictured) blazed to a 4:01.72, beating the old mark of 4:07.99 by San Diego Masters. A fourth national record was broken in the 35+ Mixed Freestyle Relay during Saturdy's competition which featured Ron Kurza, Liz Dillmann, Nadine Day, and Matt Keller.
