The Red Sox  announced that they will have 19 non-roster invitees in their big league spring training camp, including the two players widely viewed as the top prospects in their system in shortstop Xander Bogaerts and center fielder Jackie Bradley Jr. Most of the rest of the list is comprised of players who project to open the year in Triple-A or the majors, with one intriguing exception.
The team also added shortstop Deven Marrero to camp as a non-roster invitee, a development that comes as something of a surprise given that the team’s 2012 first-round pick (No. 24 overall) has played just 64 professional games, all with the Short-Season Single-A Lowell Spinners last year. Given that he wasn’t invited to the team’s Rookie Development Program, Marrero’s presence in big league camp is unexpected.
Marrero, 22, was considered an advanced college position player entering the draft, and he had a solid if unspectacular showing in Lowell, hitting .268/.358/.374/.732 with 19 extra-base hits and 24 steals (in 30 attempts) in 64 games. Still, given that shortstop is a position of depth for the Sox with Stephen Drew , Jose Iglesias , Pedro Ciriaco, Brock Holt and Bogaerts already in camp, the Arizona State alum was not expected to start the spring in big league camp. The fact that he is doing so underscores the idea that the organization thinks that there is a potential for Marrero to follow a somewhat more accelerated development path than most players who are entering their first full pro seasons in professional baseball.
At the same time, his inclusion makes one omission all the more startling — outfielder Bryce Brentz, who did take part in the Rookie Development program, isn’t listed on the Red Sox’ initial release of non-roster invitees. Brentz finished last year in Triple-A Pawtucket, and Sox manager John Farrell  recently mentioned him as a candidate to turn some heads in spring training.
Here’s how the non-roster invitees break down by position:
LHPs (1): Chris Hernandez
Infielders (7): Xander Bogaerts, Jonathan Diaz, Mark Hamilton, Justin Henry, Deven Marrero, Lyle Overbay , Drew Sutton
Outfielders (5): Jackie Bradley, Jeremy Hazelbaker, Juan Carlos Linares, Mitch Maier, Ryan Sweeney 
From the Red Sox press release, here’s a player-by-player look at the 19 invitees:
