Red Sox pitcher John Lackey's divorce from wife Krista is finally official ... TMZ has learned.
As TMZ first reported, Lackey filed for divorce back in August while Krista was battling breast cancer. She underwent a double mastectomy last March.
According to court records in Texas, the divorce was finalized on January 31. We're told there is a prenup in place, which calls for Lackey to keep his separate property for himself.
We emailed both sides for comment ... never heard back.
