One angle is to appreciate the fact that she owns the 13-fastest times in the history of the event, highlighted by five trips to sub-55 territory. That statistic reveals Walsh&#8217;s dominance and consistency. But there is another data point that honors Walsh&#8217;s excellence.<\/p>\n<p>On Saturday night, Walsh <a href=\"https:\/\/www.swimmingworldmagazine.com\/news\/flash-gretchen-walsh-blasts-world-record-in-100-butterfly-goes-54-33-at-fort-lauderdale-open\/\" target=\"_blank\" rel=\"noopener\">shattered her own world record in the 100 butterfly<\/a>, clocking 54.33 at the Fort Lauderdale Open. While Walsh sliced .27 off her previous standard, also set at the Fort Lauderdale Aquatic Center, she also moved more than a second faster than history&#8217;s No. 2 performer. Sweden&#8217;s <strong>Sarah Sjostrom<\/strong>, the 2016 Olympic champ in the event, sits second in the all-time rankings, thanks to a performance of 55.48.<\/p>\n<p>Walsh now sits 2.09% faster than Sjostrom, which is an absurd difference in a sport that is typically defined by miniscule amounts of time. However, Walsh has turned her back on that notion, taking the 100 butterfly into a different stratosphere. As wild as it might sound, Walsh could threaten the 54-second barrier before long &#8211; perhaps as early as this summer&#8217;s Pan Pacific Championships.<\/p>\n<p>Here is a glance at the largest gaps between the world-record holder and history&#8217;s No. 2 performer.<\/p>\n<h3>Women&#8217;s 100 Butterfly<\/h3>\n<p><strong>World-Record Holder:<\/strong> Gretchen Walsh (United States) &#8211; 54.33<br \/>\n<strong>No. 2 Performer:<\/strong> Sarah Sjostrom (Sweden) &#8211; 55.48<br \/>\n<strong>Percentage Difference:<\/strong> 2.09%<\/p>\n<h3>Men&#8217;s 100 Breaststroke<\/h3>\n<p><strong>World-Record Holder:<\/strong> Adam Peaty (Great Britain) &#8211; 56.88<br \/>\n<strong>No. 2 Performer:<\/strong> Qin Haiyang (China) &#8211; 57.69<br \/>\n<strong>Percentage Difference:<\/strong> 1.41%<\/p>\n<h3>Women&#8217;s 1500 Freestyle<\/h3>\n<p><strong>World-Record Holder:<\/strong> Katie Ledecky (United States) &#8211; 15:20.48<br \/>\n<strong>No. 2 Performer:<\/strong> Simona Quadarella (Italy) &#8211; 15:31.79<br \/>\n<strong>Percentage Difference:<\/strong> 1.22%<\/p>\n<h3>Men&#8217;s 200 Individual Medley<\/h3>\n<p><strong>World-Record Holder:<\/strong> Leon Marchand (France) &#8211; 1:52.69<br \/>\n<strong>No. 2 Performer:<\/strong> Ryan Lochte (United States) &#8211; 1:54.00<br \/>\n<strong>Percentage Difference:<\/strong> 1.15%<\/p>\n<h3>Women&#8217;s 400 Individual Medley<\/h3>\n<p><strong>World-Record Holder:<\/strong> Summer McIntosh (Canada) &#8211; 4:23.65<br \/>\n<strong>No. 2 Performer:<\/strong> Katinka Hosszu (Hungary) &#8211; 4:26.36<br \/>\n<strong>Percentage Difference:<\/strong> 1.02%<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Dominance of Gretchen Walsh in the 100 Butterfly (Percentage Difference) There are multiple ways to recognize the greatness of Gretchen Walsh in the 100-meter butterfly.
