The wife of Tim Lincecum -- one of the best MLB pitchers of all time -- has sadly died ... the San Francisco Giants announced on Thursday night.
She was just 38 years old.
Cristin Coleman, who dated Lincecum for years, passed away following a battle with cancer in late June ... but it hadn't been widely reported until the Giants mourned her loss in a series of tweets on Thursday.
"The Giants were extremely saddened to learn of the passing of Tim Lincecum's wife, Cristin Coleman," the team wrote.
