Both teams started the game in a sluggish fashion as neither were able to carve out any clear-cut opportunities in the opening 20 minutes of the contest.
The Dynamo opened up the match as Will Bruin raided forward, but lacked support from his teammates, and his ambitious strike from distance sailed past the post.
Ricardo Clark almost produced a moment of magic for the home side when he ran the length of the pitch and into the penalty area, but he dragged his shot wide of the target.
Deric kept his side from falling behind as he produced a diving stop to prevent Kristinn Steindorsson's shot from finding the bottom corner.
Columbus upped the ante as they pressed to get back into the match, but Deric was in fine form as he leaped to punch away a loose ball in the six-yard box as Kamara was set to pounce, securing his side the points.
