Bosley’s first game came at Anaheim Stadium on June 29, 1977. He hit seventh and started in center field. He tripled off Kansas City Royals starter Jim Colburn in the bottom of the fourth inning to plate two runs. The runs were more than enough for Angels starter Nolan Ryan, who pitched a complete-game shutout while striking out 12. California won the game 7-0.
