Analysis: Boston was seeking to add power to a lineup that hit an AL-low 168 home runs. The 30-year-old Martinez has changed his swing to improve his launch angle and become one of the top home-run threats in the majors. He hit .303 with 45 homers and 104 RBIs last year for Detroit and Arizona, which acquired him on July 18 for three prospects. He had 29 homers and 65 RBIs in 62 games with the Diamondbacks, and hit a record-tying four home runs in a game.
