Gretchen Walsh added more all-time swims to her resume this past weekend, now holding the top 11 performances all-time in the women’s 50 butterfly. Two of those swims come from the first 50 of her 100 butterfly.

Walsh swam the #3 performance all-time in the 50 butterfly with a 23.91 to win the event at the final stop of the World Cup in Toronto. That swim earned her the $10,000 triple crown bonus as she won the event in Carmel in a World Record 23.72 (another $10,000 bonus) as well as in Westmont in a 23.90, which stands as the #2 performance all-time.

Two of the performances that stand out are the first 50 splits of her 100 butterfly during the 2024 SCM World Championships. In semis, she was out in a 24.37 and in finals she was out in a 24.18. She went on to swim World Records in both swims, first posting a 52.87 in semifinals before breaking that with a 52.71 in finals.

Out of her nine performances of the 50 butterfly alone (not the 100 fly), Walsh has never been slower than the previous World Record of a 24.38 set by Sweden’s Therese Alshammar back in 2009.
