Some of the world's elite bowlers will be back in town for the 27th annual Spring Hill Open this weekend at Spring Hill Lanes.The tournament is a stop on the PBA South Region tour and includes up-and-coming professionals and established PBA veterans looking to stay sharp during the summer. Entrants will battle for an estimated top prize of $2,500.Among those who have previously entered the tournament are PBA Hall of Famers Walter Ray Williams Jr. and Jason Couch, along with current tour standouts such as Rhino Page, Patrick Allen, Dick Allen, Tom Daugherty, Tommy Jones and Jason Sterner.Daugherty, who resides in Wesley Chapel and owns Hall of Fame Pro Shop in Lutz, is one of three multiple-time winners, capturing titles in 2006 and 2008. Another is fellow local Jason Mahr. The Spring Hill resident became the first and only hometown bowler to win, in 2007, and followed with another championship in 2012.Darin Hays of Wesley Chapel holds the event record with four titles (1995, 1996, 1999 and 2000). The 52-year-old still competes from time to time and was in 16th place after qualifying at the PBA50 Pasco County Open at Lane Glo Lanes in Port Richey in April. The field included Hall of Famers Williams, Brian Voss, Norm Duke and eventual champion Parker Bohn III.Last year, St. Petersburg resident Sean Riccardi defeated Dustin Ochoa 256-214 in the finals. The New Jersey native is expected to return to defend his crown against some of the toughest in the sport after winning his second regional title at Spring Hill."With the large number of fans, it's a little bit more pressure bowling here," Riccardi said. "I don't usually get emotional, but I got excited when I clinched the title."Locals vying to become the next area winner include Anthony Caso and Bill Howell III, both of whom qualified via the Spring Hill Sweeper last weekend. The 2010 PBA South rookie of the year, Chris Polizzi, and Mahr are also expected to be in the field. The large number of bowlers who usually compete really interests Spring Hill Lanes co-owner Carlos Martins. The Martins family has operated the bowling center for almost three decades."The sport of bowling changes and evolves," he said. "It is important that we keep the competitive spirit and nature of the sport alive. …"We encourage all fans to come out and enjoy the event. It is absolutely no charge to watch."
