I don't see many big matches in the first round of the main event, but in the second round there are a couple big matches lined up assuming they defeat their first round opponent.
Antonio Lining vs Shane Van Boening (Lining has been playing really good as of late)
Lo Li Wen vs Jeffery De Luna
Tanaka Masaaki vs Johnny Archer
Dennis Orcullo vs Ko Pin Chun (again, lol)
Akagariyama Yukio vs Ramil Gallego
Antonio Lining recently won the Japan Open 10-ball this July defeating Rodney Morris in the finals. saw Lining last month in our local pool hall, and he's playing very sharp. this Lining-SVB match should be a good one.
Also, i think it was Ko Ping-Chung who eliminated Dennis Orcollo in All-Japan Open 2 years ago. Recently though, Dennis Orcollo beat Little Ko in the group round of the W9B.
