1. Boston Red Sox

■ 2016: 93-69, lost in ALDS to Indians

■ Significant additions: SP Chris Sale, 1B Mitch Moreland, RP Tyler Thornburg

■ Significant losses: DH David Ortiz, SP Clay Buchholz, 3B/1B Travis Shaw, RP Brad Ziegler, RP Koji Uehara, RP Junichi Tazawa

■ Clubhouse catalyst: 2B Dustin Pedroia

■ The season is a success if: they go all the way. Nothing else will suffice in Boston after GM Dave Dombrowski pulled off the blockbuster trade of the winter, prying Sale away from the Chicago White Sox for the hefty price of four top prospects. A front three of Sale, David Price and 2016 AL Cy Young winner Rick Porcello would be the best in the league, but Price has been dealing with elbow soreness. Moreland won’t replace Ortiz’s bat, but can play a nice first base and free up the DH spot for Hanley Ramirez. Even without Ortiz’s 38 homers and 1.021 OPS from 2016, they should have no problem scoring runs, with RF Mookie Betts poised for an MVP-caliber season, and consensus top-prospect-in-baseball Andrew Benintendi ready to break through.
