As manager Michael Jorgensen (born August 16, 1948) is an American former professional baseball first baseman and outfielder who currently works in the St. Louis Cardinals' front office.

[3] Jorgensen became expendable when the Expos acquired first baseman Tony Pérez and was traded to the Oakland Athletics at the start of the 1977 season.

Dave Roberts entered the game to pinch run for Jorgensen, and Pat Putnam took over as the Rangers' regular first baseman for the next month.

After suffering headaches, it was discovered he had a small blood clot inside his head, which apparently caused a seizure, and could have resulted in death.

On July 4, 1980, Montreal Expos rookie Bill Gullickson sailed a pitch over Jorgensen's head in the second game of a doubleheader.

The Mets sold him to the Atlanta Braves the day they acquired first baseman Keith Hernández from the St. Louis Cardinals for pitchers Neil Allen and Rick Ownbey.

[6] In 2001, Jorgensen began working as a senior special assistant to St. Louis Cardinals general manager John Mozeliak, scouting the American League.
