Schomberg was 21 when he broke into the major leagues with the Pittsburgh Alleghenys of the American Association.

On December 1, 1886 the Alleghenys traded Schomberg with $400 to the St. Louis Maroons for Alex McKinnon.

Schomberg set career-highs in almost every offensive category, including games played, plate appearances, at bats, runs, hits, doubles, triples, home runs, RBIs, stolen bases, batting average, slugging percentage, and on-base plus slugging.

In two seasons with the Hoosiers, Schomberg hit .288 with 23 doubles, 17 triples, six home runs, 93 RBIs, and 27 stolen bases.

He holds the Hoosiers' single-season record for on-base plus slugging and triples, and he is second in on-base percentage, third in slugging percentage, fourth in batting average, runs batted in, and bases on balls, sixth in runs scored, seventh in total bases, eighth in home runs, and tenth in hits.
