Frank Cashen, the architect of the 1986 world champion New York Mets, died Monday, a team spokesman said. He was 91.

Cashen served as Mets general manager from 1980 through 1991, transforming the organization from a perennial loser into a juggernaut.

The bowtie-wearing GM engineered the June 15, 1983, trade that brought Keith Hernandez from the St. Louis Cardinals to the Mets. He also invigorated a farm system that produced Dwight Gooden and Darryl Strawberry.

Cashen regularly attended spring training games in Port St. Lucie, Florida, even through this March.

He previously served as an executive with the Baltimore Orioles when they won titles in 1966 and 1970.
