What do you think Bello would get as a FA? Have you seen what some pitchers with way worse records than Bello have gotten, recently?
He's owed $50M/4 or $70M/5: 26:$6M, 27:$8.5M, 28:$16M, 29:$19M, 30:$21M club option ($1M buyout)
I know the arb equation is vastly different than the FA equation, but many GMs would love to have Bello at this cost.
Yes, some of the low budget teams would not want him at this cost but would take him for a couple arb years, then maybe trade him, assuming he gets to expensive.
