The 6-foot-3 Briscoe must have been impressive because his father, George, told Cardinal Authority that his son now has a U of L offer.
"I figured it would take a lot to impress someone like coach Pitino," George Briscoe said. "Isaiah was pleased with his workout and I'm pleased as his father.
"It went well and he has an offer."
Briscoe is considered the No. 7 shooting guard in the country, according to Scout.com., and the No. 26 player overall in the Class of 2015.
Pitino has said his staff would likely have two scholarships open for the '15 class.
Arizona, St. John's, Rutgers, Connecticut, Seton Hall are among the others recruiting Briscoe. When asked about U of L being on the list after the visit his father said, "Absolutely, they are up there."
"Louisville is an elite program with an elite coach," George Briscoe said. "It's a program that we have to really look at closely."
Briscoe is expected to make a visit sometime perhaps this summer to U of L. He will play in the Nike EYBL this weekend in Sacramento, Calif., where he will be evaluated by Pitino and staff.
