With his team down by a point at halftime, Lindsay, who was held scoreless in the first half, delivered a layup and a runner, and Anthony capped the run with a 3-pointer that induced Old Dominion coach Jeff Jones to call timeout with 17:01 remaining.
A few minutes later, after the Monarchs had cut their deficit to four, Lindsay scored on a spinning layup, then stole the inbounds pass and converted two free throws to boost the Spiders lead back to eight. Old Dominion couldn't get closer than seven points throughout the final 14 minutes.
Guard Aaron Bacote had 20 points and freshman forward Denzell Taylor chipped in 14 points and 11 rebounds for the Monarchs (5-8), who were unable to get their transition game going. Richmond turned it over just seven times and struggled to solve a stingy Richmond half-court defense throughout.
Taylor accounted for all five of Old Dominion's second-half field goals until Bacote's 3-pointer with 2:26 left.
The Monarchs shot 37.5 percent in the second half and fell for the seventh time in eight games.
The Spiders, meanwhile, got a boost from Anthony, whose defense and 3-point shooting ignited Richmond after a sluggish start. His back-to-back 3-pointers wiped out an early 12-9 Old Dominion advantage.
Later, Anthony poked the ball away from Bacote near midcourt, then caught a return pass from Lindsay for an uncontested fast-break layup to put the Spiders ahead 22-19.
The Monarchs quickly returned fire, though, as 3-pointers from guard Dimitri Batten and Mosley nudged Old Dominion in front 25-22. A layup from Richmond forward Terry Allen got the Spiders to within a point. Neither team scored over the final 3:06.
