Martinez injured his ankle in Game 1 and looked hobbled when running during Game 2, but is still set to hit fourth and play in the outfield for the first time in the postseason after previously serving as Boston's designated hitter.
"Definitely the trainers put me through a little bit of a workout testing it out," said Martinez, who warmed up in right field shortly before Boston announced its lineup. "(The ankle) is something that obviously, it's a little discomforting, but I'm comfortable with playing, and definitely going to go out there and do our best."
Martinez led the American League with 130 RBIs in the regular season and was second in both batting average (.330) and home runs (43). He's hitting .333 with 13 RBIs in the playoffs.
Benintendi, hitting .283 in the postseason, went 4-for-5 in Game 1 against the Dodgers but 0-for-3 with two strikeouts in Game 2. The decision to sit Benintendi allows the Red Sox to keep ALCS MVP Jackie Bradley Jr. in center field and leadoff man Mookie Betts in right.

Shortstop Xander Bogaerts will move up to the second spot normally occupied by Benintendi, followed by first baseman Mitch Moreland and Martinez. Second baseman Brock Holt will make his first appearance of the World Series, hitting fifth and replacing Ian Kinsler, who had gone 1-for 7 at Fenway Park.
After losing the World Series' first two games in Boston, the Dodgers will feature four new faces -- left-handed hitters Joc Pederson, Cody Bellinger and Max Muncy and switch-hitter Yasmani Grandal -- in the starting lineup against Red Sox righty Rick Porcello.
Red Sox manager Alex Cora also said Nathan Eovaldi is "slated" to start Game 4 on Saturday, though the right-hander could also be used out of the bullpen in Game 3 if needed.
Eovaldi, who pitched perfect eighth innings in each of the first two games, then confirmed he would not start Game 4 if he pitched in Game 3.
