The Rockies catchers are a bit of a weak spot for the team, particularly at the plate and it shows in their overall ratings.
Depending on updates and such, Wolters is first and Nunez is second but it seems to be consistent that Butera is third and Diaz is fourth.
I do find it a bit ironic that Nunez, at least by this version, is the Rockies’ best catcher. However, of the four, he seems least likely of the four to make the Opening Day roster.
At first base, the Rockies have three men on their 40-man roster. One of them is a bit surprising.
McMahon is the only guy that seems to differentiate… but only on ratings as some have him as high as 73. Either way, I would think that he would be a bit higher. The primary position can change overall ratings as well and if he were to be listed as a second baseman as he should be, his rating would likely be closer to where it should be.
