Pat Howell toiled in the Mets minor league system for five seasons before finally getting the call to the Majors in 1992. He made his Major League debut on July 10 against the Houston Astros as the Mets leadoff hitter and centerfielder. He singled in his first at bat and immediately stole second base. It looked like the Mets had found their new catalyst at the top of their lineup. Unfortunately, from that point on, despite being one heck of a defensive centerfielder, Howell struggled at the plate. He appeared in 31 games for the Mets but hit just .187 and drove in only one run.
Following the season, he was traded to the Minnesota Twins in exchange for Darren Reed. His one season with the Mets would be his only season in the majors.
While with the Mets Howell wore number 38.
