Jonathan Herrera: Utility infielder was obtained from the Rockies for Franklin Morales.
A.J. Pierzynski: Veteran catcher accepted a one-year deal. He represents the biggest acquisition of the winter.
Grady Sizemore: Idle for two years because of myriad injuries, the former All-Star is attempting a comeback.
Edward Mujica: Former Cardinals closer is late-inning insurance.
GOING, GOING, GONE
Jacoby Ellsbury: So much for loyalty, he’s now with the Yankees.
Jarrod Saltalamacchia: The Sox took a pass when he became a free agent, so Salty returned to Florida and became a Marlin.
MAN WITHOUT A COUNTRY
Stephen Drew: He’s still a free agent, meaning the Red Sox could bring him back.
PROSPECTS TO WATCH
Henry Owens: The 21-year-old lefthander won’t make the team but he could set himself up for midseason promotion.
Blake Swihart: Another 21-year-old, the athletic catcher could be the starter in 2015.
Garin Cecchini: Infielder has an advanced approach at the plate.
Deven Marrero: Shortstop made a good impression in big-league camp last year.
Center field: The Red Sox signed Sizemore to compete with Jackie Bradley Jr. If Bradley doesn’t win the job, he could go back to Triple A.
Rotation: There are six starters for five spots. Somebody has to go to the bullpen . . . or to another team.
Bullpen: There’s a spot or two up for grabs and plenty of contenders, as usual.
SPRING STORY LINES
Repeat after me: No major league team has repeated as champion since the 2000 Yankees. You can expect to hear that a lot.
Peeved Papi: David Ortiz has been lobbying for a contract extension. Will that become a running theme?
More of Les: Jon Lester has said he will take a hometown discount to sign an extension with the Sox. Your move, Ben Cherington.
X marks the spot: Xander Bogaerts will likely start at shortstop or third base. The 21-year-old could be Boston’s version of Manny Machado.Peter Abraham can be reached at email@example.com. Follow him on Twitter @PeteAbe.
