Brian Cashman knew the Chicago White Sox wanted a lot in a trade for Chris Sale and the New York Yankees weren't willing to part with potential superstar Gary Sanchez.

Sanchez hit 20 home runs in 53 games after being promoted on Aug. 3

The Boston Red Sox eventually gave up Yoan Moncada, Michael Kopech, Luis Alexander Basabe and Victor Diaz for Sale on Dec. 6.

"You saw what the White Sox got for Sale," Cashman said.

"I try to play in my mind what the equivalency would be with the Yankees," the general manager said. "Is Moncada the Gary Sanchez? You'd have to give up a Gary Sanchez-type. Would it be the equivalent of Moncada?

"And then you have to play around with the next (piece). Is it (a touted pitching prospect such as James) Kaprielian or Chance Adams or Justus Sheffield? It would probably be (Luis) Severino right now. So those are the two primers just to get the ball rolling with the other two players yet to be named to try to match up for Sale."
