20 Dom Nunez

On one hand, Nunez hung around the Mendoza line last year for the second time in his pro career then followed it up by going 4-for-44 in the Arizona Fall League. Nunez has fallen off many Rockies top prospect lists. He is already Rule Five eligible.

On the other hand, Nunez is a switch-hitting catcher who was the everyday starter at Double-A at age 22, which is 2.3 years younger than the norm in the Eastern League.

His good offensive years feel so long ago and the Rockies catcher of the future seems like a title that comes with the guarantee of bust upon attachment.

Reports love his arm behind the dish — he gunned down 34 percent of runners last year — his blocking ability — cutting down on passed balls big time — and the way he commands a staff. Baseball Prospectus put it well, “I wouldn’t be shocked if Nunez only sees a cup of coffee as a third catcher or if he has a 15-year career.”

The offense may have dried up for now but that might not always be the case, what seems to be forever though is unez ability to be a backstop and that can get a pospect to the big leagues.
