Marie-Sainte is 33-2 but has mostly crushed cans. His best win is a narrow UD over the awkward Belghecham who made Barker look bad a while back. One of his two losses was an SD over 8 rounds to area level British fighter Tyan Booth in a fight which took place in Canada for some reason. This should be fairly straightforward for Murray against an opponent who has not faced anyone close to his level.
