A guy who one day might be a back end of the roster type player or a guy who might be a valuable trade chip if he continues to flash a semi decent hit tool is Chesney Young, the 2B in AA Tennessee. Young has (and will likely never be) a high rated prospect seeing as he was a 14th round college player out of Mercer in the 2014 draft.
While he lacks power, age 23 slash line of .320/.424/.460 is right around his career minor league numbers and he's flashed decent speed with 7 SB and only 2 CS.
The thing about Young is that he simply doesn't strike out. Only four K's on the year in 55 PA after having just 51 in 510 PA in combined A ball last year. He does not hit for power but if the bat continues to profile as a high contact / low SO bat with decent speed, he could be a bench player in a few years. I could see him at AAA next year (if he has a season close to how it's started) as Alcantra could be moved back to a CF role if Almora's with the big league club and then Young can be a guy fighting for a roster spot in 2018 as a right handed LaStella.
