Ratzer made his Major League debut on the final day of the 1980 season In 1981, Ratzer appeared in 12 games, all in relief. On April 28 at the Philadelphia Phillies, he relieved starter
Charlie Lea, pitching a
three up, three down fifth inning. Because the starting pitcher did not pitch the requisite five innings to earn the victory, the
official scorer awarded the win to Ratzer, which proved to be the only win of his major league career. On May 14 at the
Los Angeles Dodgers, he relieved
Bill Gullickson pitching another 1–2–3 eighth inning. However, he recorded his only loss when he surrendered a lead-off,
walk-off home run to
Pedro Guerrero in the next inning. Three days later Ratzer was sent back down to the minors. ==Post-MLB career==
