Allen joined the PBA in 1999, and became a full-time PBA Tour player the following year. He won his first PBA title in 2001 at the Greater Detroit Classic. His finest season as a pro came in 2004–05, when he earned PBA Player of the Year honors and led the Tour in points. That season, he made match play in 19 of 21 events, made five TV finals appearances, won three titles (including his first major) and cashed a career-high $350,740 in earnings. Allen also made the top-five in all four major tournaments in 2004–05, the only time that had been accomplished since the ABC/USBC Masters became an official PBA event in 1998.[1]
Allen added three titles in the 2008–09 season, at the National Bowling Stadium Championship, Tournament of Champions and Dydo Japan Cup. He has not won a title since that season.
In the 2009 Pepsi Red, White and Blue Open, Allen set a PBA record for total pinfall in a 48-game qualifying block, both scratch (11,888) and with bonus pins (12,308). The record still stands as of the conclusion of the 2017 season.[2]
Known to his fans and fellow pro bowlers as "P.A." or "Hoss," Allen became the PBA's 36th career millionaire in 2007. He was ranked #44 on the PBA's 2008 list of "50 Greatest Players of the Last 50 Years." Through the 2016 season, he has recorded 41 perfect 300 games in PBA events.
Allen also has won 30 PBA Regional Tour titles. He represented the PBA East Region and won the 2015 PBA Regional Challenge finals, a non-title event held at the PBA World Series of Bowling in Reno, NV. In the victory over defending PBA Regional Challenge champion Josh Blanchard, Allen rolled the first ten strikes of the game before leaving a 6-pin on the eleventh shot and settling for a 289 game.[3]
