I don’t think you’re going to get a cornerstone bat this early before the deadline, especially in the AL with so many teams in the hunt.
That being said I’d take a chance on:
Jo Adell
Spencer Torkelson
Hunter Goodman
Jake Burger
Josh Bell
CJ Abrams (highly unlikely)
Byron Buxton could solve a lot of the Red Sox problems if the Twins decide to take calls on him.
Wouldn’t be cheap and injury concerns always there but would be the perfect middle of the order right-handed bat.
