Playing for the Lyons Lions, he batted .362 and slugged .594 with 13 home runs; those three stats were each league-leading totals.

He made his major league debut on May 12, 1911, and spent the season as a reserve outfielder.

In 1913, he rebounded with a big season, leading the AA in triples (23), home runs (12), and total bases (280), while batting .292.

However, Riggert again failed to stick; he hit just .203 in 1914 for the National League's Brooklyn Robins and St. Louis Cardinals.

In 1920, Riggert led the American Association in triples for the third time and helped the Saints win their second straight pennant.

The 1920 St. Paul squad was named by minorleaguebaseball.com as the sixth-best minor league team of all-time.

Riggert was passed by other players and was no longer one of the premiere minor league sluggers.

However, he continued to put up good numbers every year, and in 1924 he got his 2,000th minor league hit at the age of 37.
