The matches on the winnerside:
Shane Van Boening vs Jose Parica
Mika Immonen vs Shawn Putnam
Johnny Archer vs Brandon Shuff
Daryl Peach vs Raj Hundal
Rodney Morris vs Adam Smith
Petri Makkonen vs Thorsten Hohmann
Francisco Bustamante vs Oscar Dominguez
Lee Van Corteza vs Ronnie Alcano
Some real good match-ups here. I am very surprised to see the kid from Finland, Petri Makkonen, doing so well. I have seen him in 2 tournaments earlier, and he played awesome in the final of the European Youth 8-ball Championships, but I didn't think his skills were good enough for a performance like this. Well done Petri, and good luck against Thorsten!
For some reason I think that Jose Parica will beat Shane Van Boening. No matter what happen, I believe it will be a very close match. Jose Parica is perhaps the player that wants this title the most. (Imagine if he wins the whole event, I guess that the first thing people will tell him is: Well, Efren didn't play this year

)
The most interesting match here is definitely between the two Filipino superstars, Lee Van Corteza and Ronato Alcano.
I have just finished watching two matches on YouTube, Lee Van Corteza - Shane Van Boening (race to 25), and last year US Open match Lee Van Corteza - Niels Feijen.
Lee Van is playing some serious pool right now, but I think that Ronato Alcano is still a hair or three better than him, and that Alcano will win this matchup. However, my guess is that both these players, no matter who will win, will end up in Top 8 in this tournament.
