I'd guess Elias has a significant bias to Ruiz, in the same way MacPhail was biased to Felix Pie.
Ruiz was maybe his biggest play as a draftee. The used some savings from Correa in 2012 to sign McCullers Jr as a 1S pick and they gave Ruiz 1.85M as a 4th round pick to talk him out of his USC commitment.
He's sitting at 1.109 for service and this year they had one of the lowest Super 2 cutoffs at 2.115 so he's unlikely to be a Super 2 next year if everyone basically gets a year of service. He's just miss, like some guys like Matt Chapman did this year.
At 25, he's got 600 PAs over 4 season with the biggest opportunity coming last year and an OPS under .700. An 81 OPS+ isn't going to get it done.
It doesn't look like the Orioles have any 3B options prior to Gunner Henderson who is 3-4 years out..
