SPLIT COMPARISON

Mijatovic-Finals Mijatovic-Prelims Heilman
Fly 52.63 53.59 50.86
Back 1:00.24 59.53 59.45
Breast 1:05.05 1:05.17 1:08.71
Free 51.4 52.75 52.44
3:49.32 3:51.04 3:51.46

The difference tonight in fianls compared to his prelims swim was both Mijatovic’s fly and free split as he was roughly a second faster on both.

Mijatovic now dropped over six and a half seconds off of his best time coming into the meet of a 3:55.73 from April of this year.

This was Mijatovic’s second swim of the night as he swam the 200 free earlier in the evening, swimming a 1:36.30, a best time by over a second.

Mijatovic is entered in the 500 free, 1000 free, and 200 IM later in the meet. Notably, he broke his own 1000 free NAG record last night while going out in the 1650 free, where he ultimately broke his own NAG by 15 seconds.
