Callaway joined the Indians organization in 2010 as a minor league pitching coach and worked his way up the ranks. The Indians made it to the World Series last year and won 102 games in 2017, due in no small part to a potent pitching staff that led the A.L. in ERA this season.
Callaway will be replacing Terry Collins, who was fired at the end of the 2017 season. He will have an intriguing, if injury-plagued, collection of arms to work with in New York.
