I'd almost be willing to bet something like this scenario happened. Where the Angels basically were all in on Ayers, Jed was not. Jed pivoted to Braxton has his controllable arm and now he's open to get another controllable arm or a rental for the rotation.
Is it though? Ballesteros is a DH. A DH who already had somewhat questionable power. On top of that, his weaknesses got hard exposed this year and it has translated over to AAA.
