In February 1968, the Giants were in need of good infielders, and with four young catching prospects, including Dick Dietz and Dave Rader, club president Chub Feeney decided to trade Haller along with a player to be named later, to the Dodgers, for infielders Ron Hunt and Nate Oliver. The trade was the first between the two teams since their move to the West Coast in , and also the first since the one that would have sent Jackie Robinson from the Dodgers to the Giants after the season. Haller played well in 1968, posting a .285 batting average, in 144 games, and earned his third consecutive All-Star berth. He also played well defensively with career-highs in assists (83) and in double plays (23). He guided the Dodgers' pitching staff to the second best team earned run average in the league, although the team finished the season in seventh place.
