Question: How many years of professional experience did Andy Seminick have when Mack Burk pitch-ran for the catcher? Passage:Burk stood tall, weighed and threw and batted right-handed. He attended the University of Texas at Austin and signed a $40,000 bonus contract with the Phillies in September 1955. Under the rules of the day, a "bonus baby" such as Burk was compelled to spend his first two years as a professional baseball player on a Major League roster. In his pro debut, on May 25, 1956, Burk pinch-ran for catcher Andy Seminick. In his third game, on June 5, he pinch hit for pitcher Curt Simmons in the fifth inning and singled off left-hander Joe Nuxhall of the Cincinnati Redlegs. He came around to score his first big-league run that inning on a sacrifice fly by Stan Lopata. He scored two more runs during the 1956 season, both as a pinch runner. In his lone appearance in the field, Burk caught one inning, the bottom of the eighth, in relief of Lopata on July 25 against the Cardinals, and handled one chance flawlessly.
