That seems like that would be the plan, right? Vientos is just a bench piece. Tong is a cheap add to the rotation. sox use savings to add to 1b/3b.
Again, we're talking about a trade that came from NY talk radio. Not exactly something that is coming from reality to begin with so it's nothing I'm taking seriously.
I honestly don't know enough about Tong to say if he's worth it in a trade for Duran. He's not the #2 that Breslow said he wants, just another question mark to add.
