Jeffrey Joseph Fassero (born January 5, 1963) is a former Major League Baseball pitcher. Professional career Montreal Expos Fassero was drafted by the St. Louis Cardinals in the 22nd round of the amateur draft, but he bounced around in the minors for several years until he joined the Montreal Expos in . At 28, Fassero was somewhat old for a rookie, but pitched well for the team and eventually made it to the starting rotation by the season. That same year he posted an impressive ERA of 2.29.

San Francisco Giants Fassero signed with the Giants on December 15, , and remained on the team until May 8, 2006 when the Giants designated Fassero for assignment.
