The choices range from Daniel Nava to maybe even someone like Alex Hassan. All these options have the potential to earn the position, but there is really only two options in my book.
Nava has been a mainstay in the Red Sox's organization since his grand slam in his first ever plate appearance in a Boston uniform against the Philadelphia Phillies in June 2010. It was the greatest moment of his major-league career and he didn't even hit another home run until 2012.
The Red Sox did not seem to need him in 2011 with the likes of Carl Crawford, Jacoby Ellsbury and J.D. Drew roaming the outfield. He wasn't even called up in September during the most historic collapse in MLB history.
Even through dealing with some injuries in 2012, the switch-hitting outfielder made some strides and will fight for his right to make it on the 25-man roster come April. He finished the last season with six home runs and 33 RBI in limited playing time. He made some momentous defensive plays throughout the season and showed his great arm strength numerous times in left field.
Who will be the fourth outfielder for the Red Sox
Sweeney was included in the deal that acquired Andrew Bailey, but only managed to stay healthy for 63 games in a Red Sox uniform after hurting himself by punching a door and going after a flyball.
The left-handed outfielder has an opportunity to move up from a minor-league deal that he signed recently with the Red Sox, according to ESPN, to once again be on the major-league roster.
The 2012 season was very successful in right field with some great reads on balls in the gap and even some sliding catches that made it on SportsCenter throughout his first year with the Sox. His left-handed approach of the Boston bench will be a nice presence if the Red Sox decide to go that way.
