At the turn, Morita was 1-up on Nino, but both players halved the 10th hole. Then on the 11th, Nino missed his putt, while Morita drained his to go up 2.
Nino, who made some tough putts to beat defending champ, Alex Ching, a day earlier, struggled on the greens against Morita.
On the 13th hole, Nino had a chance to win the hole, but he missed a short putt to fall 3 back of Morita.
Morita goes on to beat Nino, 1-up, and will now face T.J. Kua in Saturday's Championship Final.
