I agree about the Westburg/Ortiz part.
I'm also curious to get more insight in Bob's think regarding Jackson. I'm guessing that it's more about Gunnar and fitting Mayo in than anything negative about Holliday.
As for Mayo at 2B, based on what Bob has said, I think Coby's arm is his best defensive asset which would be useful but less valuable at 2B. I'm guessing his D wouldn't be all that good at 2B otherwise either if he profiles as an average third baseman despite the cannon.
Yeah it’s nothing against Holliday. His defense has improved throughout the year but has lagged behind his offensive development (how could it not) so putting him at 2B at least to start his career could help ease him in.
Mayo is 6’5’’, 230 at 21 years old and has never played up the middle defensively as a pro. It’s either 3B, corner OF, or 1B for him and one of the first two would allow him to use his 70 grade arm.
