Nice Job Grace!
Her and her TWIN sister, Addy, are two of the best 11-12 swimmers in the nation RIGHT NOW!!!
They rep Northwestern’s age group club program, NASA Wildcat.
They casually went 1-2 in the 200 free amidst their individual races.
The team website messaging is the finest I’ve ever seen.
Coach bios…every link in the chain strong!
Mike Jones and Peter Linn are smiling, Kate.
Would have placed 4th at D2 Nationals last night
faster than my freestyle as a guy at that age lol
Way to go Grace! Unbelievable preformance.
What a great year for Illinois Swimming.
