Lidge is a two-time All-Star who closed for the Phillies, Houston Astros, and the Washington Nationals during his 11-year major league career.
"Lidge was released by the Nationals last June, after struggling to make a comeback from April surgery to repair a sports hernia," ESPN's Jayson Stark wrote in article about the 35-year-old impending retirement.
In 11 seasons, Lidge saved 225 games in the regular season and 18 more in the postseason.
Stark writes that is "the second-highest postseason save total in history, behind only Mariano Rivera."
In 2008, "Lights Out" Lidge was perfect, going 41 for 41 in save opportunities.
The biggest save of all came, of course, at Game 5 of the 2008 World Series, when he struck out Tampa Bay's Eric Hinske for the final out.
