"Her butterfly swim was real solid," Kansas coach Clark Campbell said. "Amy had another good swim this morning. We will now move onward and upward to the Aggie Invitational."
Gruber will compete in the Aggie Invitational on Sunday, March 21. The event will be in short course meters and give her an opportunity to receive Olympic trial cuts in the 50 and 100 freestyle.
