That's when the Golden Eagles will play for fifth place in the eight-team tournament against the winner of a game between Texas and USC. Marquette, which is unranked but receiving votes in the AP Top 25, wants a strong finish to its Hawaii trip.

Gardner finished with 15 points and 12 rebounds.
Mississippi State didn't score in the first four minutes as the Golden Eagles built an 8-0 lead. Gavin Ware hit a jumper and Craig Sword had a steal and dunk to make it 8-4, but Marquette responded by scoring 10 straight points in less than two minutes. Marquette led 48-27 at the break.
Williams said he thought his team was efficient in the first half.

Mississippi State coach Rick Ray said injuries kept his team from being able to make substitutions — for mistakes in the first half and fatigue in the second.
"They haven't given up, the team worked hard, played hard," Ray said. "We are just so short of bodies right now when you are playing three games in three days against quality competition."
The Bulldogs lost two freshmen for the season earlier this year, and Jalen Steele is out at least six weeks after breaking a wrist last week.
The tournament format — each team playing three games over a three-day span — put Monday's four losers into a consolation bracket.
Marquette lost Monday to Butler on Rotnei Clarke's buzzer beating 3-pointer to open the tournament. Later the same day, Mississippi State was torched by No. 9 North Carolina, which hit 15 3-pointers.
