No this is not a spoiler alert. 
FS1 has already broadcast this more than once since yesterday's first broadcast and the highlights/winner is already out on youtube.
So with that said, I want to not only say congrats to Norm, but thank him for one of the best championship final matches I have witnessed in many a year.
He truly without any doubt, is one of the greatest of all time!

Well dang.  I guess I’m late to the congratulations party. Guess Norm won’t see mine now. Glad the op was able to though on here and in person when Norm invites him over for afternoon cocktails

Congrats to Norm, He bowled great on the show.

To those who are complaining about spoilers.

While the OP could have added a spoiler notice to the subject, If you don't want to know the results why would you go to a bowling website and then go to the PBA folder? There is a high likely hood a spoiler could exist.

 You don’t have to go to the PBA folder.

 The winners name shows up on the front page, in the title of the post.

 Log in, and BAM, instantly shows in title of post.

 Besides, it has LONG been common practice here to post SPOILER ALERT in your title instead of the winners name in the subject line (title) of your post.

 Most sensible, practical, responsible, thoughtful users here know that.

 Others don’t care, I suppose.

 Oh yeah, congratulations Mr. Duke. You’ve come a long way since Mt. Pleasant.

Norm, PDW and WRW (Bohn, Aulby, etc) make that generation the greatest ever imo.   The young bucks have a whole lot of work to do to catch up.  Gratz to Norm making it that much harder.
