Doug McDermott scored 21 of his 33 points in the second half, Austin Chatman had a career-high 19, and No. 23 Creighton defeated Tulsa 82-72 on Saturday.
McDermott recorded his 16th career 30-point game. He also became the first Creighton player since Cyril Baptiste in 1969-70 to open a season with four straight 20-point games.
The Bluejays (4-0), playing as a Top 25 team for the first time this season, opened the second half on a 13-4 run to increase its 42-41 halftime lead to 55-45. McDermott had eight points during the spurt, closing the surge with two straight 3-pointers.
Rashad Smith had 21 points, Pat Swilling added 18 and James Woodard 11 for Tulsa (0-4). Shaquille Harrison, who was averaging a team-high 19.5 points, was held to seven.
McDermott played a strong all-around game, grabbing 15 rebounds. He also made three 3-pointers, 12 of 15 free throws and had a couple of steals. Chatman was 4 for 5 from long range and had nine assists.
Creighton held an eight- to 12-point lead for most of the second half until Tulsa made a late run. Rashad Smith banked in a shot off Rashad Ray's fast-break pass, got fouled by Devin Brooks and made the free throw to make it a seven-point game. Smith scored again after a Brooks turnover to make it 73-68 with 3:51 left.
The Hurricane had a chance to make it a one-possession game with 2 minutes left, but Swilling was way off with a 3, and McDermott hit a long shot on the other end to restore the Bluejays' eight-point advantage.
Chatman came into the game with 16 assists and no turnovers in three games, but he was needed as a scorer early against a Hurricane team that hung tough through the first half.
He made seven of his first eight shots, and his 3-pointer with five seconds left in the half gave Creighton its one-point lead at the break.
Chatman's fourth 3-pointer came early in the second-half run that broke open the game. McDermott followed with two shots from beyond the arc, the second one ripping the net as he fell backward.
The Bluejays led by as many as nine in the first half. Tulsa went on a 16-7 run to tie it, and Swilling's layup gave the Hurricane a brief lead.
The Bluejays have won four straight in the series against their one-time Missouri Valley Conference rival. Now they're off until they play Arizona State on Thanksgiving night at the Wooden Legacy tournament in Fullerton, Calif.
Creighton has won 45 of 46 regular-season November home games since 1990.
Tulsa hasn't beaten a ranked opponent since Dayton in the 2003 NCAA tournament. The Hurricane, who lost at home to Wichita State on Wednesday, was playing a second straight ranked opponent for the first time since 2002.
