Bobby Jenks, a former All-Star closer and key figure in the Chicago White Sox’s 2005 World Series victory, has d**d at the age of 44, the team confirmed Saturday.

Jenks passed away Friday in Sintra, Portugal, where he had been undergoing treatment for adenoca**inoma, a type of stomach ca**er, according to CNN.

A dominant presence on the mound, Jenks played a crucial role in the White Sox’s championship run, recording four saves across six postseason appearances in 2005. He was named an All-Star in both 2006 and 2007, racking up 41 saves in ’06 and 40 in ’07, solidifying his status as one of the top closers in baseball during that era.

Bobby Jenks was a dominant MLB pitcher best known for his role as a closer with the Chicago White Sox during the mid-2000s. Born on March 14, 1981, in Mission Hills, California, Jenks overcame a challenging childhood and early setbacks to rise to professional baseball success. He was originally drafted by the Anaheim Angels in 2000 but was released due to injuries and discipline issues. Shortly after, the Chicago White Sox picked him up—a move that would change his life.
