"Former World Series Champion Cole Hamels Calls it Quits After 15 Seasons in MLB"

Former World Series champion and left-hander Cole Hamels has announced his retirement from Major League Baseball (MLB) after a 15-season career. Hamels, who signed a minor-league contract with the San Diego Padres earlier this year, never made an official appearance with the team due to shoulder surgery. He finishes his career with a 3.43 ERA and four All-Star Game appearances, playing a key role in the Philadelphia Phillies' 2008 World Series victory. Additionally, right-hander Craig Stammen, also with the Padres, has been placed on the voluntarily retired list after suffering a shoulder injury.
