Alex Hassan might be the oldest, 25, prospect on my top 30 Boston Red Sox prospect countdown and most certainly will be the only one to have spent three years at AAA, but he does still hold prospect status.
Hassan has average to slightly above-average power and has a five-year career minor league batting average of .292. He has a very good approach at the plate, career .401 OBP, making him a prototypical Red Sox hitter. After starting the season injured, not effectively starting his season until mid-May, he dominated in AAA. He hit .328 and got on base at a .457 clip.
The depth of options in the outfield are really the only reason Hassan did not make his debut in 2013. Another reason is he is not exactly a great defender, or even a particularly good one. He has below-average range in left field and even began to see time at first base late in the season to broaden his value and ability to help the big league team in 2014. He will never be a starter but rather a bench guy who will likely spend the majority of 2014 being shipped between Pawtucket and Boston.
Depending on injuries and offseason additions, Hassan could quickly run through his minor league options in 2014 so he could be a candidate to be moved in July. In terms of value to the Red Sox, it is immediate. He could play out as a right handed version of Mike Carp and help the Red Sox right from opening day. He may be a career quad-A type player, but he certainly has the ability to bring some value on the field this coming season.
