Moises Sierra, the Jays newest addition of an unproven outfielder that needs seasoning but will only be give a few atbats to become a MLBer before being traded to another team. :) From what we understand this guy has some great raw tools, a big arm that he showed off last night. Average speed, no plate discipline and good power, his average of .289 in Las Vegas doesn't strike me as a guy that is a top prospect? Well that is because he isn't anything more than a serviceable MLBer potentially. Vegas is a place where the pitchers hit .200, so the fact that Sierra hit in the 240's does not make me that confident in his abilities. In comparison, David Cooper is hitting .314 at Vegas and won the PCL batting title in 2011. The funny thing about this is he is still not considered a prospect by most watchers. Is this a positive step forward??
