Well we've got Holliday, Mayo, Kjerstad, and Cowser all knocking at the door but we're unsure which (or any) will be on the Opening Day roster.
So, if they are all in Norfolk I'm not sure who our 13th hitter is. I've got Rutschman, Mounty, Westburg, Urias, Henderson, Hays, Mullins, Santander, O'Hearn, McCann, Mateo, and McKenna. That's 12. I suppose this scenario paves the way for Hilliard as #13.
Then throughout the season we add the four rookies, supplanting Hilliard, Mateo, McKenna, and Urias... maybe in that order. With injuries perhaps Urias sticks, and/or whichever right handed backup CF looks better. Mateo is making $2.7m so I'm guessing they want him to find a home as a backup CF.
