The White Sox have informed Rule 5 pick Adrian Nieto, who was plucked from the Nationals organization, that he will make the Opening Day roster, his agent Joshua Kusnick tweeted. Nieto beat out Josh Phegley (who was optioned on Wednesday) and Hector Gimenez for the right to back up incumbent Tyler Flowers.
The 24-year-old Cuban native has never played above the High-A level. Last year, he put up a .282/.371/.446 line with 11 home runs in 448 plate appearances as a 23-year-old. Checking in as the Nats' 30th overall prospect entering the season (per Baseball America), Nieto is said to be a work-in-progress behind the dish who could become an average defensive backstop. His calling card is his bat, with BA saying that the switch-hitter could become an offense-first MLB catching option.
Of course, Chicago will need to keep Nieto on its 25-man roster for the duration of the season to keep his rights going forward.
