I think a little of both.
Maybe wrong...but I thing he is looking to play it off the 9 in the corner, or hang it there.
He looks at getting behind the ball near the bottom rail, but would have to hit it shallow angle with inside, or stun and let the bank go wide, to hold it, and likely miss the 9. If it goes, he doesn't have a shot on the 5. (not a good shot) from low on the rail
Then he looks at it from lower corner to top corner, for the 6? to provide cover if it hangs, and if it goes, he can shoot the 5. Hitting it with spin to get the cb where he wanted, the ob banked wide and headed toward the side off the 3rd rail...the speed was good...so the best of both worlds...
..he hit it bad enough to be real good...the key part was a good cb and a good choice between two way shot selection options. If the ob had caromed off the 9 and hung up, the cb was hooked behind the 6?
No doubt, Morro had some 'aiyaiyai's to say' at that moment as he stood and watched the ball creep into the side...
...Keith got a roll, but, it came from a good shot choice, and cb execution.
