Jeff Jones will return next season as Tigers pitching coach and Dave Clark will join Detroit as third-base coach and outfield instructor under new manager Brad Ausmus, the club announced on Wednesday.
Clark spent the past five seasons with the Astros, serving most recently as first-base coach after four seasons as third-base coach. He served as the team’s interim manager in the final 13 games of the 2009 season.
Jones returns to the club after serving as pitching coach since July 3, 2011. Jones began his professional coaching career in the Tigers organization in 1989, when he was a pitching coach at the Minor League level.Jeff Jones To Return As Tigers Pitching Coach by Charles Mager
