The Yankees are currently 6.5 games out of first place in the American League East and for the first time in quite a while, they could be sellers at the trade deadline.

There's been a lot of speculation that if the Yankees fall out of the race, they should consider selling off pieces like Carlos Beltran and potentially even reliever Andrew Miller.

If the Yankees fall out of it, they should NOT trade Miller, they should trade Aroldis Chapman.

Why? Miller has two more years left on his deal with New York, so trading him would yield the biggest return because the acquiring team would still have two years of control.

Chapman is a free agent at the end of the year so trading him would yield a smaller "rent-a-player" return, but the Yankees would have the ability to sign him back at the end of the offseason. And if they did that, they would have Dellin Betances, Miller and Chapman together again.
