Robinson connected from long range to snap a 45-all tie with 5:55 to go. Starks missed a 3 at the other end and Robinson drained another deep one before Garrett barely beat the shot clock with a tough basket in the lane to give DePaul an eight-point cushion.
Georgetown cut it to 55-52 on two free throws by Smith-Rivera after Young fouled out with a minute to go. DePaul’s Durrell McDonald put up a desperation 3 to beat the shot clock, then alertly grabbed his own rebound when it bounced long off the front rim.
Garrett, who picked up his Big East rookie of the year trophy at a news conference earlier in the day, then hit all four of his free throws in the final 22 seconds to seal it.
“In shootaround and practice, Coach preached free throws. He said every one counts and it’s going to come down to free throws, and it did,” said Garrett, the son of DePaul assistant Billy Garrett. “So we listened to that, and we paid attention to it in practice, and we worked on it. When it came down the stretch, it really did come to free throws, and we were able to knock them down.”
Robinson went 4 of 5 from behind the 3-point line. The junior forward matched his career high for points, set Feb. 19 at Xavier.
DePaul’s previous win over Georgetown was 78-51 at home on Jan. 22, 1994. Purnell improved to 1-6 against the Hoyas.
Georgetown jumped out to an early eight-point advantage before the Blue Demons went on an 11-0 run to grab their first lead with just more than 5 minutes remaining in the first half. Robinson hit a 3 during the spurt for DePaul, which was 1 for 10 from beyond the arc in the opening 20 minutes and finished 5 for 19 (26.3 percent).
Smith-Rivera’s layup stopped a 6:30 scoring drought for the Hoyas, who regrouped to take a 25-23 lead into the locker room.
“We’ve been through a lot with the program this year,” Georgetown guard Jabril Trawick said. “I think it’s disappointing we didn’t come out with the win, but at the end of the day, I think that we’re a tournament team. I mean, we’ll see.”
