The White Sox have outrighted catcher Adrian Nieto off the club’s 40-man roster, per a club announcement (h/t to Dan Hayes of CSNChicago.com, on Twitter). After also losing Junior Guerra via waiver claim, the team has three open 40-man slots.
Nieto, 25, was taken from the Nationals in the pre-2014 Rule 5 draft. The White Sox carried him all year, even as he slashed .236/.296/.340 over 118 plate appearances. That earned the team permanent rights over the Cuban native.
Known as a defensively-gifted backstop who would need work at the plate, Nieto did not take much of a step forward in 2015. Optioned to Double-A to start the year, he put up a .207/.344/.316 slash line with five home runs over 315 plate appearances. Nieto did carry a strong 16.5% walk rate, but was retired 24.4% of the time via strikeout as well.
