It might be as simple as they want him to play and won’t call him up to sit on the bench. Maybe they think he’s actually got a chance to be good. Or at least adequate for an extended period. If Kike gets hurt, they really have no choice, barring another move.
They might even think Dalbec can handle shortstop for a few innings or even a full game without derailing the entire season. They also clearly don’t care if Dalbec comes up to sit, which might be a bigger factor than we realize.
Just a thought…
