2012 US OPEN
The U.S. Open is one of the four major tournaments in the Professional Bowlers Association. The first modern-day U.S. Open tournament in the PBA took place in 1971 and was won by Mike Limongello. Prior to 1971, this event was known as the BPAA All-Star. BPAA All-Star winners in the PBA era (1959-1970) were initially not credited with PBA titles for their victories. A rule change in 2008, however, retroactively awarded titles to the winners if they were PBA members at the time of their victories. With five wins, Pete Weber holds the most U.S. Open trophies of all time.
