DeMarco wins at his best in a ten round bout. He was leading Basilio if I remember through 10 round both times and Turner lost to Basilio in 10.
DeMarco stops him late, anytime after the 9th methinks. Turner`s lack of defence would be his undoing, as he wasn`t hard to hit and against a come forward banger like DeMarco he wouldn`t stand up to that kind of firepower for a full fifteen. It would be fun while it lasted, but Turner is going down and out eventually although he wouldn`t go quietly and would make a fight of it until he got stretched out for the count.
