The Yankees eventually countered by offering Vazquez, Halsey, pitcher Alex Graman, another prospect and enough money to pay a significant chunk of Vazquez's salary. But the Diamondbacks turned that down.
I thought that the Yankees' offer was extremely high. I have no idea what the Diamondbacks are thinking. I don't remember what the deal was when Randy was traded from the Mariners to the Astros, but I am sure that it wasn't this good, and that was when RJ was at his prime. There is no way they will get a better deal than that from any team.
That is unless they can trade for BOTH Chacon and Kenny Rogers.
