The Dodgers made two changes to their 25-man roster for the World Series, adding pitcher Brandon McCarthy and shortstop Corey Seager, and removing outfielder Curtis Granderson and catcher/infielder Kyle Farmer.

Seager’s return was expected after he missed all of the National League Championship Series with a back injury. The 23-year-old batted .295 during the regular season with 22 home runs and 77 runs batted in. He played all three games in the NL Division Series despite a sore elbow that impeded his throwing.

Early in Game 3 of the NLDS, Seager injured his back sliding into third base. He received an epidural injection the following day but couldn’t recover in time for the NLCS. Journeyman Charlie Culberson stepped into the lineup and went 5-for-11.

Whicker: Astros offer Dodgers a stiff 7-game challenge Culberson is on the World Series roster too, and could see time in the infield and the outfield. He’ll allow manager Dave Roberts to deploy Seager as a designated hitter when the World Series shifts to Houston in Game 3.

Granderson’s .067 batting average in the postseason was the lowest among Dodger position players with at least 10 at-bats. Kiké Hernandez, Chris Taylor, Yasiel Puig, Andre Ethier and Joc Pederson offer ample outfield depth without Granderson, who bats left-handed. Ethier, Pederson, Chase Utley and switch-hitter Yasmani Grandal all offer manager Dave Roberts left-handed bats off the bench.

Since he was acquired from the New York Mets in August, Granderson has more strikeouts (26) than hits (19).

Farmer was a luxury, a right-handed hitting catcher who gave Roberts the flexibility of using Barnes and Grandal in the same game. But he batted only four times in eight postseason games without a hit. The Dodgers will carry only two catchers during the World Series.

The most surprising addition was McCarthy, who’s pitched all of six innings since July. The 6-foot-7 right-hander has been restricted to simulated games and bullpen sessions since the regular season ended, but could become a useful multi-inning option out of the bullpen.

McCarthy, 34, went 6-4 with a 3.98 earned-run average during the regular season. He began the year in the Dodgers’ rotation and posted a 3.84 ERA in 16 starts. But the veteran was never fully healthy, whether it was a right knee injury that caused him to miss a start in July, or a recurring finger blister that caused him to miss all of August and most of September.

When he returned from the blister, McCarthy worked exclusively out of the Dodgers’ bullpen. In three relief appearances to end the season, he allowed four runs in six innings. His last game was a two-inning relief stint on Oct. 1.

The Dodgers’ pitching staff will feature eight relievers, including six right-handers: McCarthy, Ross Stripling, Josh Fields, Kenta Maeda, Brandon Morrow and Kenley Jansen. Tony Watson and Tony Cingrani are the only left-handers.

Clayton Kershaw will start Game 1, Rich Hill Game 2, Yu Darvish Game 3 and Alex Wood Game 4.

The Astros made no changes to their American League Championship Series roster.
