With the 2015 spring training just 4 1/2 months away many questions linger on where to play these future players. The outfield for instance is loaded with center fielders. Rusney Castillio in his brief tenure has made an impression with both his bat and glove.Far more ahead than teammate Jackie Bradley. Its no doubt Bradley needs a full year at Pawtucket. Hes a minimum 500 at bats before his next big league opportunity. Mookie Betts is in the same category as Castillo good with both the bat and in the field. Yoenis Cespedes provides good protection for David Ortiz. Cespedes has a great arm and is a legitimate power threat. Right field could be interesting Bryce Bentz has also made a favorable impression on Red Sox coaches. Danny Nava ‘s time with the Red Sox could be up . His trade value is high with his versatility. He has good pop in the bat and can play first as good as any one. Who can forget Brock Holt the super sub of 2014.Holt will go to the instructional league and gradually get over his concussion. That leaves third base rookie Garin Cechchini shows great leather and could push third year man Will Middlebrooks out of a job. Middlebrooks hit a mere 190 after two straight seasons of injury. Catching wise Christian Vazquez seemsto be a lock for next year with his awesome arm and handling of the pitchers It is unclear if veteran David Ross will be back. Minor leaguer Blake Swihart swigs a potent bat and is excellent defensively No doubt the Sox braintrust will be very active this off season.
