This is an interesting match-up, a 24-year-old who has blossomed quickly into a champion-caliber player against a 46-year-old who has achieved the highest order of excellence already in pocket billiards.
There are many determining factors which go into the equation of who's the favorite and who's the dog in this race.
Shane, because of his youth, has endurance. Though I don't think being 46 is over the hill quite yet, since I'm 53 --

-- Earl's game is multi-faceted. Many people say it will depend on which Earl will show up. Earl's got the skills set to beat Shane, no question in my mind whatsoever.
I do know from reading the pool media that Earl has been and still is suffering from kidney stones. At the WPC recently, he told a Filipino reporter that he was in pain. I saw Earl at two events when he played pool suffering from those kidney stones.
At the Trump Marina 10-ball Championship in Atlantic City, Earl was taken to the emergency room one night during the event because of the pain, but he somehow managed to make it to his match the next afternoon. He was wearing a jacket over a sweater. Because he suffers from pain, one side effect, maybe from the medication, is that he gets cold very easily. He also performed at the Carolinas Open a few years back, after having come from the hospital because of these kidney stones.
Shane suffered an infected foot at the WPC, but I think his foot has recovered by now. Earl, on the other hand, still is plagued by these damn kidney stones.
So which Earl will show up to play Shane? If he's not in pain, we may see Earl's best game. I know when I am sick and/or in pain, I cannot bang out as many pages for my job as I can when I feel good.
Now, I am not making excuses for Earl or Shane. I am just stating some facts that do come into play when speaking about these two matching up two days from now.
I believe Earl's seasoning in broadcast and high-profile events will be an asset to Earl's corner. I think Shane's determination and 10-ball skills will be an asset to Shane's corner.
If I were the bookie making a tout sheet, I'd want to survey the horses right before the race, check out their gait, their mood, their activities the day before the race. We're in the blind here back at home, but if both players bring their best game to the table, I think it is a pretty even match, weighing in all the variables.
JMHO, FWIW!
