Nate Sexton (OR), Kyle Crabtree (WA) & Tim Skellenger (OR) have the best chance of a top 10 finish
Here are a few others to keep tabs on:
Sean Phillips (OR)
Dustin Keegan (OR)
John Anderson (WA)
Either of those three could make top 15-20 and have been shooting a lot of 1040+ rounds lately. There are also a few sleepers:
Chandler Fry (WA) is starting to get back into the groove after playing a little less the years past, his game is coming together nicely the last few months.
Jame Moore (OR) has been plagued by some head problems in past years, but he's been playing a lot lately, and working on his mental game. If he can keep his temper under control he has all the skill necessary to make top 20.
Jason Pinkal (OR) has been sitting at about 1000 for a while and with a win last weekend is hopefully pulling out of a small slump that he's been fighting lately. He's got a very strong mental game, I'm hoping for a top 25 finish out of him.
Brian Cook (WA) is the most dominant player in Eastern Washington. I'm really interested to see how he handles playing in this field. He's also a LHFH player, which is should help him a bit on BSF East.
