DAYTON, Ohio (AP) — Dyshawn Pierre scored 21 points, and Dayton led a double-digit lead slip away before rallying to beat Richmond 63-60 on Saturday night, remaining unbeaten at home. The Flyers (16-3, 6-1 Atlantic 10) led by 10 points at halftime but went cold at the start of the second half, allowing the Spiders (10-9, 3-3) to make it a game. Richmond was coming off an 89-63 win over Davidson last Saturday, piling up season highs in points and 3-pointers (14) in the Spiders' most lopsided win of the season. Cline scored 10 consecutive points — including a pair of 3-pointers — that gave the Spiders their first lead, 47-46, midway through the half. Jordan Sibert, the Flyers' leading scorer at 16.1 points per game, picked up his fourth foul with 8:54 to go and finished with eight.
