Two back-to-back World records from Gretchen Walsh of the USA at the World s/c Championships in Budapest this evening - first a 52.87 in her 100m butterfly semi followed by a 55.11 victory in the 100m medley - took her tally of global standards in 4 days to 7 ... a record of records the University of Virginia ace coached by Todd DeSorbo and team staff at the home of the NCAA women's champions.
