What does "eve of the the All-Star game" have to do with this mayor's illness?
I once stubbed my toe a mere month prior to the Superbowl. It must have been connected.
All-Star game is being held in Pittsburgh and Murphy has had the place spiffed up. It's his chance to bask in the glory, but now he has to seek treatment for the cancer.
I was wondering that myself, as if the "occasion" made it particularly tragic.
