I dont understand the negativity on Kieboom. Just about every scouting service had him as a top tier prospect. His draft position and minor league numbers support those rankings.
Basically it comes down to a 2 week stint in the bigs. Trout struggled in his first taste. Vlad struggled in his first taste.
Kieboom is a game, from a baseball family, and is very talented. It's fine to question how good hell become. But to write him completely off is ridiculous. Maybe he becomes a zero at the big league level. Just about everyone that is paid to cover the sport thinks hes a legit big leaguer. Give him more than 2 weeks.
For my money, hes going to prove to be a legit big leaguer this year and hit 20 bombs. He will be our 3rd baseman over the course of the next 5 years, and Garcia will eventually become our 2b.
