William A. Sharsig (1855-1902) was the esteemed GM and field manager for the Philadelphia Athletics in both their incarnations from 1886-1891. As the founder and co-owner of the original Athletics franchise, Sharsig named himself field general several times. When the Players’ League folded in 1891, he continued in baseball with the Western League’s Indianapolis club.

• His prestige in MLB prompted the NL to invite him to consult on the decision to move the mound to 60’6” in 1893
• A Philadelphian born and bred, Sharsig died there at age 46 on the eve of accepting Connie Mack’s offer to return as business manager
