Another virtuoso offensive performance showed the world why sixth-seeded Creighton was a preseason top-10 team — and what its potential is now.Ryan Kalkbrenner dropped 22 points, Baylor Scheierman added 21 points on 5-of-7 3-point shooting and Creighton shot 58.2 percent to take down 15th-seeded Princeton 86-75 in the NCAA Tournament’s South Region semifinals on Friday in Louisville.Creighton made its second Elite Eight in program history — the first came in 1941, when the tournament had just eight teams — and will vie for its first trip to the Final Four. The Bluejays (24-12) will face fifth-seeded San Diego State in the Elite Eight on Sunday.The high-octane Bluejays made 32 of 55 shots, including Kalkbrenner’s 9 of 12 and Scheierman’s 8 of 11. Scheierman added nine rebounds as the Bluejays outrebounded Princeton 37-26 and never trailed by more than four points.Trey Alexander scored 19 points, Arthur Kaluma had 10 and Ryan Nembhard put up nine points and eight assists for Creighton.Princeton (23-9) was vying to become the second No. 15 seed ever to make the Elite Eight, but they couldn’t match the feat of New Jersey neighbor Saint Peter’s last year.Ryan Langborg led the Tigers with 26 points on 11-of-17 shooting, and Tosan Evbuomwan supplied 24 points, nine assists and six rebounds.Creighton made eight shots in a row en route to a 10-for-13 start from the floor and a 24-16 lead. Then the Tigers’ Caden Pierce waltzed in for an open dunk, which began to turn the tide for Princeton.Evbuomwan made his first of two 3-point attempts after he had made nine all season prior to Friday. He scored or assisted on 13 of Princeton’s 19 made field goals in the first half.
