I don't think Efren can win a nudge battle with the 3 ball. He has lots of shots available. I would probably either just roll into the 14 trying to keep the CB right in front of the 14 (so Corey would have to shoot over the 14), or bat the 14 away with low english leaving the CB on the rail. That leaves a very long tough cut on the 9, of which if Corey misses, the game is over. Even he were to make it, he'd only get one or two.
There again, Efren happened to pick the wrong shot in the previous inning. A three ball cluster in that position is tough to free up using the lead ball. He should have banked the 9 to his own hole, leaving whitey up on the center head rail; or he should have simply batted it away, leaving the CB tough. He should have thought to himself, "What would Nick Varner do here?"
