National's Capital Aquatic Club, or NCAP, broke their 2nd National Age Group Record of the weekend in Friday morning's prelims, and still neither has come from Katie Ledecky (though she's having a spectacular meet of her own).
This morning's swim came from Andrew Seliskar in the men's 100 breaststroke, where he was a 54.11 for the 14th seed. That broke the 2008 time swum by Cody Miller in 54.38; Miller is now at Indiana and is an Olympic Trials semi-finalist.
There were two other 16-year olds who were very fast in this race. Pleasanton's Nick Silverthorn was 17th in 54.67 and Dynamo's Gunnar Bentz, who already has a NAG Record in this meet from the 200 IM, was tied for 20th in 55.00. Silverthorn actually becomes with this swim the 4th-fastest of all-time, jumping ahead of the great Brendan Hansen.
Seliskar will be in the B-Final tonight, while the other two will be in the C-final. A middle lane for Silverthorn might see him spurred on to a 54-low as well; Bentz (along with Seliskar) will have the 400 IM final right before this 100 breaststroke so he could be tired by the time this race rolls around; much less ress in the finals sessions.
NCAP also got a NAG Record on Thursday from Janet Huin the 50 free. She's got a chance at getting the 100 fly record tonight, with a 52.61 in prelims off of a record of 52.43. Both Hu and Seliskar train under John Flanagan at the Tyson's YWCA site in Northern Virginia, and both did a lot of developmental work with Marilyn Mangels prior to that.
