Cashman said the Yankees' intention is to keep Miller, Betances and Chapman for 2016. Cashman is not ready to declare a closer yet. All three have pitched in different roles and whatever inning they throw, they should be a dominant trio. Cashman also has the option of eventually trading Miller, clearing money (Miller is owed $27 million over the next three years) and perhaps adding a starter. For now, though, on the field, the Yankees are much better for 2016 with an overwhelming pen. They do have risk, bringing in Chapman considering his domestic violence situation.
On the field, this trade is a no-brainer, considering the discount bin price. Off the field, it remains to be seen.
It's quite possible they just mix and match the 3 of them as opposed to actually naming a closer. That's not exactly what the Royals have done, but it's certainly a possibility. Having 2 lefties and a righty for the last 3 innings, they can pretty easily match up with any lineup in the league if they aren't defining a 7th, 8th, and 9th inning guy. I'm definitely interested to see how the Yankees play it with the 3 of them this year.
