Two-time All-Star reliever Kirby Yates says he is retiring after making his first start Saturday in a 12-year big league career. The 39-year-old Yates, who went undrafted out of junior college, shook hands with teammates and plate umpire Laz Diaz while leaving the field after pitching 1 2/3 innings for the Pittsburgh Pirates. It was Yates' 518th appearance since debuting with Tampa Bay in June 2014, and he confirmed after the game that it was his last.
