On this match, Corey made a ball on the 16th break, but didn't notice it. Apparently neither did Shane. Shane then came to the table and finished the rack for the match.

Should Shane have been awarded the win?
You said corey made a ball and didn't notice it? you think pro's would not notice the corner ball going in? hehe, no my friend, it was just an illegal break, they both very much noticed the 3 ball going in.
Some tournys use the rule that either 3 balls should be pocketed or go past the kitchen line, or a combo of either but total of 3 should be accomplished, and in that break, he just made the 3ball he needed 2 more balls to either pocket or go past the kitchen, which didn't happen.
Oh and to answer your final question, yes Shane won, the break was illegal, he should have broken harder.
