Mattingly originally was hired by manager Joe Torre to be the Dodgers' hitting coach after he lost the competition to replace Torre as Yankees manager to Joe Girardi.
But Mattingly soon backed out of the position because of family issues and accepted a reduced role as a special hitting instructor who spent time with the club in Spring Training and on occasional Midwest trips. Mattingly was on Torre's coaching staff with the Yankees.
Easler is the Dodgers' eighth hitting coach in the past 10 seasons.
