Santos is a grappler who looks to end fights on the mat — of his 9 wins, 1 come by knockout, 5 by submission, and 3 by decision. He's a genuine finisher: 67% of those wins came inside the distance. Tellingly, none of his 2 defeats came by finish — he's durable and hard to put away, losing on the cards rather than getting stopped. He's most dangerous once it hits the canvas; rangy strikers who keep it at distance pose the stiffest test.
