Minnesota (11-2) went on an 18-2 run early in the first half and remained in control despite stretches of sloppy play. The Gophers, who will host Michigan in the Big Ten opener on Thursday, shot 12 of 22 from the free-throw line and 37 percent from the field.
Minnesota missed six of its first eight 3-point attempts before Austin Hollins drained two in a row late in the first half. With the student section at Williams Arena half full and the alumni band filling in as the regular band traveled back from the Gophers football bowl game in Houston, Minnesota tried to shake off the rust after playing just one game in the previous 17 days.
Jeff Beverly led the Islanders (3-10) with 10 points and Rashawn Thomas added eight. Leading scorer John Jordan was held to five points on 2-of-7 shooting. Corpus Christi turned the ball over 18 times, shot 35 percent and made just one of 15 3-pointers.
The Islanders trimmed Minnesota's lead to nine on two different occasions and trailed 32-21 at halftime. Minnesota opened the second half on a 17-3 run and led 45-22 with 13:33 left to play after an Andre Hollins four-point play.
Texas A&M-Corpus Christi has one NCAA tournament appearance in 12 years and has only won six games each of the past two seasons. After starting this season 3-2, the Islanders have now lost eight straight and are heading into their Southland conference opener on Thursday at Central Arkansas.
