Jenks went public with his diagnosis in February, when he revealed he was suffering from Stage 4 adenocarcinoma and was undergoing treatment in Portugal. At that time, the former White Sox closer admitted that his prognosis was poor, but that he intended to fight as much as he could.

Jenks became a fan favorite during his time with the White Sox. He debuted in 2005 and became the closer on a World Series team. Eventually, he made two All-Star appearances while with Chicago in 2006 and 2007. He finished his career in 2011 with the Boston Red Sox and was out of the league before turning 31.

The White Sox are slated to honor the 20th anniversary of their 2005 World Series championship team, of which Jenks was a part, from July 11-13.

In 348 career games, Jenks posted a 3.53 ERA and collected 173 saves.
