Virgil had an active career that spanned 37 years from 1932 through 1968. Back in 1932, the year "Babe'' Ruth hit .341 and pounded 41 homers, Virgil Siemer, a 5-foot-8 shortstop weighing 125 pounds, signed a Muny Contract with the old Stroot and Carroll team. Other clubs over the years were Vogel Cafe, Vess Soda, Stags, Carter Carburetor, Lindell Trust, Meyer Barbeque, Breheny's, Rauth's, Milkay's, Kelly's, Borbein-Young, Kutis, and the Printers.

Virg attracted attention while playing in the old Trolley League with Vess and the Stags. A super intelligent baseball man who was an excellent fielder at any infield position (including catch), Siemer led the Championship Belleville Stags in hitting with a .366 average in '35. He spent five years in professional ball with stops at Moline, Clinton, and Norfolk. 

In his baseball travels Siemer was associated with not less than 16 different clubs, winning 13 pennants and eight championships.
