"Alex" Main was a 30 year old rookie in 1914. His three saves ranked sixth in the league that year.
The following season, he became the second Tiger pitcher to jump to the short-lived Federal League, the first being Ed Willett (). He played for the Packers that season. Although his ERA of 2.54 was third best on the team and he gave up only 181 hits in 230 innings, his record was only 13-14. He had the worst record on the team among all pitchers with at least 25 games started. Despite that, his 1.113 WHIP was fifth best in the league, and his 7.08 hits per nine innings ratio ranked second. His three saves were eighth best in the league that season. On August 16 of that season, he threw a no-hitter - that was the first no-hitter in Federal League Park history ().
He spent part of 1918 pitching for Lebanon in the Bethlehem Steel League in Delaware.
