Rafael Devers and Sam Travis, two of their top prospects, were among the nine non-roster players the Red Sox invited to spring training.
Devers, 20, had a .779 OPS for Single A Salem last season. This will be his first spring training with the major league team.
The 23-year-old Travis excelled in spring training last season, hitting .469 with 13 RBIs in 18 games. He then played 47 games in Triple A before a knee injury ended his season.
The Sox also invited first baseman Allen Craig, catcher Jordan Procyshen, outfielder Brian Bogusevic, outfielder Rusney Castillo, and righthanded pitchers Kyle Kendrick, Chandler Shepherd, and Ben Taylor to camp.
Craig hasn’t played in a major league game since 2015. The Red Sox took him off the roster after that season but still owe him $11 million.
Castillo, 29, has hit .262 in 99 games for the Red Sox after being signed to a seven-year, $72.2 million contract in 2014. The Sox took him off the roster last season but are responsible for the $46 million remaining on his deal.
Castillo and Craig are unlikely to make the team, as their salaries would then count against Major League Baseball’s competitive balance tax limit.
Kendrick, 32, has not played in the majors since 2015. He is 81-81 with a 4.63 earned run average in 253 games with the Phillies and Rockies. Kendrick was 7-6 with a 4.46 ERA in 20 minor league games with the Angels organization last season.
Bogusevic, 32, hit .167 for the Orix Buffaloes in the Japanese Pacific League last season. He has 321 games of major league experience with a career OPS of .709.
Shepherd finished last season with Triple A Pawtucket, then pitched well in six appearances for Escogido in the Dominican Winter League. Taylor advanced to Double A Portland last season. He is a former seventh-round pick.
Procyshen, 23, has hit .254 in three minor league seasons.
