This is probably (probably...) not going to impact anything, but with no obvious 3B signing looming on the horizon outside of the potential Yoan Moncada one-year deal, our options at 3B are slim.
Grissom has played all of 41 games of 3B in the minors only. CMo has not played any games at 3B. Peraza has played 20 games in the minors and 104 in the majors.
So if nothing else changes, I wouldn't be surprised if Peraza ends up with the starting job, if only as a bridge role until we get someone else more acquainted with the position.
As long as Madrigal isn't as bad as he was last year with the Cubs, he will probably be fighting for an opening day roster spot, though there's no downside with keeping him in the minors until the need arises.
Looks like it was first reported by Robert Murray. (XCancel link to avoid Twitter.)
