It was UMBC's (4-26) first defeat to open tournament play since 2003-04, their first season in the conference.
Grant led UMBC with 17 points, hitting six of 11 shots from the floor and three of six from behind the arc. Satchell, an All-Rookie team member, posted his second career double-double with 14 points and a career-best 12 rebounds.
Two Retriever starters competed despite injuries which nearly kept them out of the lineup. Senior Matt Spadafora, who played in his 119th career game, second on UMBC's all-time list, was limited with a wrist injury. Sophomore Chris De La Rosa suffered an ankle injury in practice on Thursday, but played 35 minutes and recorded six assists and just one turnover.
Vermont took advantage of UMBC fouls, as they hit 26 of 38 shots from the free throw line, while UMBC was 12 of 18. Catamount senior guard Maurice Joseph led all scorers with 19 points, hitting four of six from behind the arc, while forward Marqus Blakely added 18 points and 12 rebounds.
After UMBC's Robbie Jackson hit a field goal on the first possession of the game, Vermont went on a 15-0 run to lead, 15-2, just five minutes into the contest. The Retrievers were plagued by foul trouble in the first half, as they were whistled for 13 fouls and the Catamounts hit 15 of 20 from the free throw line. Vermont built the lead to as many as 18 points at 28-10 with 9:30 to play in the stanza, but Satchell scored eight straight UMBC points and a Brian Neller three-point field goal cut the deficit to 34-21 with 4:57 to play.
The Catamounts had a 40-26 advantage at intermission and held UMBC without a field goal for the first five and a half minutes in the second half. They built a 51-28 lead, but UMBC battled to the end, forcing 16 Vermont turnovers and making the Catamounts battle for 40 minutes.
Jackson was whistled for three first half fouls and picked up his fourth 2:24 into the second half.
Both teams shot below 40 percent from the floor, with Vermont at 39.7 (23 of 58) and UMBC at 36.8 percent (21 of 57) . Vermont outrebounded UMBC, 46-35, and outscored the Retrievers, 14-8, on second chance points.
