I'm going to guess our bench ends up being Grichuk/Tellez, Kirk, Panik and Davis. Davis has done well this spring and having the pinch running/defensive substitutions late in games is pretty important.
There will be a lot of games where Grichuk plays in the field and Teo DH's with no OF left on the bench. Yes, Biggio can play OF but unless there's injuries, there's no need to move him all over the diamond this year. Especially when the difference between Davis and Espinal is minimal.
