VIRGINIA BEACH, Va. — If you’re looking for story lines at the 2012 U.S. Open 9-Ball Championship, the winners-side final four should provide plenty. Efren Reyes, Jose Parica, Alex Pagulayan and Shane Van Boening remain unbeaten. Young vs. old, Philippines vs. U.S., former champions chasing titles or an overdue contender closing in on his crown, the final 24 hours of the U.S. Open should be riveting.

Parica, 63, is chasing his first Open title after finished second in 2003. He will face the 29-year-old Van Boening, who has been absolutely dominant thus far. In a superb match against Ronnie Alcano — a rematch of the 2007 final, won by the American — Van Boening erased a late two-rack deficit to take an 11-10 victory.

On the other side of the bracket, Pagulayan and Reyes will square off. The Magician has been nothing short of magical in his march through the right side. He topped two-time reigning champ Darren Appleton, 11-10, on Thursday afternoon, then outlasted Wang Can, 11-7, that evening. On Friday, he then trumped Dennis Orcollo, leader of the Philippines’ next generation of stars, 11-7.

Over on the one-loss side of the bracket, it’s tough to find a player without top-tier credentials. Johnny Archer faces Darren Appleton, with the Englishman plodding through the left side in search of his third straight U.S. Open title. World 9-Ball champ Chang Jung-Lin, China’s Li Hewen and Netherlander Niels Feijen top an impressive international class of hopefuls.

Stay tuned, as updates will be posted as each round of play concludes.
