Adding David Cone to the Blue Jays in 1992 was a clear move to try and add an ace to their World Series run to increase their chance of winning, it worked and the Jays won the 1992 World Series.
By the time the 1992 season came along, David Cone was known as a strikeout ace. Because of this, the Jays went out to get Cone in a late-season deal. Despite already having an ace like Dave Stieb, Cone would give them a stellar rotation that no lineup could get through.
This is what the trade looks like:
To Toronto: David Cone, RHP
To New York (NL): Jeff Kent, IF, Ryan Thompson, OF
Jeff Kent wasn’t a remarkable player when the Jays traded him.
