In the 84th minute, Reinwald scored her 35th career goal to take sole possession of second place on the program's all-time scoring list. Junior midfielder Keily Funk sent a pass up the middle to Reinwald inside the 18-yard box with the senior sending it in for her ninth goal of the season.
Senior goalkeeper Caroline Robert kept the Golden Griffins (8-5-1, 3-1-0 MAAC) in the contest with four saves in the first half off quality opportunities, including a pair of shots off the post.
Rider's (8-4-2, 1-2-0 MAAC) best chance of the half came in the 15th minute on a breakaway following a Griffs' turnover in their own end. Rider forward Bridgette Bartkowski stormed in on Robert with the goalkeeper making a sprawling save to the right to punch the ball away from the goal with the shot ringing off the post.
Off a corner kick in the 29th minute, leading goal-scorer Abi Cottam managed to collect the loose ball and fired a shot from 10 yards out with the ball ricocheting off the top post.
After a tight-scoreless first half, Rider tallied five unanswered goals to grasp a 5-0 lead.
Ten minutes into the second half, the Broncs' Cottam scored back-to-back goals in the 55th and 56th minute to give Rider a 2-0 lead.
Midfielder Claire Thompson extended Rider's lead with a pair of goals in the 60th and 74th minutes, including a rebound shot off the post.
Cottam closed out Rider's offensive assault on the Griffs, picking up a hat trick in the 82nd minute off a one-timer from 18 yards out, giving the Broncs a 5-0 lead.
In the contest, the Broncs outshot the Griffs, 20-13 with Cottam accounting for a quarter of her team's shots. For the second straight game, the Griffs were led by Reinwald with five shots.
Robert finished the day with seven saves while Rider goalkeeper Danielle Singson recorded four save for the victory.
"We need to learn how to play two hard games in the conference. You can't have a good game on Friday and a bad game on Sunday. You'll never make the playoffs if you play that way," said Canisius head coach Jim Wendling.
