Kendall Anthony scored 21 points and Richmond hung on in the final minute to beat No. 13 UMass, 58-55, last night in Richmond, Va. UMass (16-2, 3-1), which had won six straight since a 60-55 loss to Florida State on Dec. 21, fell for the first time in Atlantic 10 play. Anthony made his first four 3-point attempts for Richmond (13-6, 3-1), including one from the right side after the Minutemen had closed within 52-48 with 4:10 remaining. Sampson Carter had 15 points to lead UMass. He made a 3-pointer with 2:26 to play, and when Cady Lalanne followed a Richmond miss with a dunk, the Minutemen were within 55-53 with 38.3 seconds to play. Cedrick Lindsay made 1-of-2 free throws with 26.7 seconds to go, giving the Spiders a three-point lead, but after UMass star Chaz Williams had his driving layup attempt blocked by Alonzo Nelson-Adoda, Trey Davis scored for the Minutemen with 11.3 seconds to play, making it a one-point game. Davis then hit Lindsay with a long inbound pass over Williams, who fouled him. Lindsay made both free throws, and Williams’ long 3-point try at the other end was off the mark.
