The two hirings fill out the primary coaching positions for new manager Scott Servais, who previously had named bench coach Tim Bogar, hitting coach Edgar Martinez, pitching coach Mel Stottlemyre Jr. and third base coach Manny Acta.
“Casey brings a great presence and high baseball IQ to our staff,” Servais said. “He’ll be working with our outfielders and on baserunning, both areas that he is uniquely prepared for given his experience over the past five years. Mike brings a tremendous amount of experience. His competitive nature will team well with Mel Stottlemyre as they help guide our pitching staff through the season.
