As they say, it's not my money. I see the advantages of adding a veteran presence to the bench that can provide coverage at second, third, and corner outfield positions as well as another RH bat. Of course, it may not work out, but Harrison might just make a positive contribution to the 2023 team.
He does provide a RH second base option if Stott struggles with LHP this season, although I guess Sosa did that as well. We will see how it works out.
He also can fill the mop up, position player pitching role.
