As seen in the chart, there is some correlation of Walsh’s first 25 indicating she will go on to swim a faster time than if she were out slower. Her 50 free and 100 fly first 25 splits are typically similar. The 50 free has a flip while the 100 fly has her pacing for a 100 so the two have different reasons why they may be similar.
Walsh is the top seed tonight heading into finals of the 100 fly after swimming a 47.21 to break her own NCAA and American Records this morning. No other swimmer was under 49 seconds.
