Gansey had just four points (2-3 from the field) and three rebounds, and suffered one turnover while starting alongside Syracuse's Gerry McNamara. The U.S., tied after one period, ran off 48 points in the second quarter to move out to a 21-point halftime lead.
Earlier in the day, Joe Herber, coming off the bench for the first time, had six points on a pair of three pointers as the German team crushed China 115-69. Herber also had one steal in the contest.
Both teams will play again on Thursday as the second round classifications continue.
