The only reason we hasn’t played at least AA ball is because of COVID.
Not all prospects are required to delay their arrival due to COVID. It’s something to consider for sure, but it’s not a rule. Everyone thinks he’ll hit, he was drafted 3rd overall as a refined college bat two years ago now...at it’s not like he’s been anywhere close to overmatched this spring. Oh, and last year the Sox managed a very productive lineup with a DH that OPS’d 627. Of course you play him.
(Almost same exact age as Kirilloff. Drafted higher. Performing much better in ST. And I haven’t noticed anyone here suggesting starting Kirilloff out of the gate would have been an act of desperation on the Twins part, despite the fact that Kirilloff would be replacing someone who OPS’d 792)
