Selleck is an avid ice hockey fan and has been seen attending Los Angeles Kings games at Staples Center. He lists Anže Kopitar and Alexander Frolov as two of his favorite players. He was once a minority owner of the Detroit Tigers, his favorite baseball team since childhood. In preparation for his role in the film "Mr Baseball", Selleck reached out to the Tigers to practice with them during the spring of 1991. He took batting practice for three weeks, even making an appearance in an exhibition game against Cincinnati, where Tiger manager Sparky Anderson had him play in the pinch hitter role. Selleck believes his training helped him considerably in his film role, having gained valuable experience from attending team meetings and developing an understanding of how competitive players function together.
