Very true.  Gossage did say in his interview with Harold Reynolds that his longest stint was probably an 8 inning appearance when he came in the 6th, gave up the tying run then finished the game. 

 

I don’t think he said if he won the game or not.

 

Update:  I believe I found the game he was talking about.  Here is a game between the Red Sox and White Sox where Gossage pitched 7 2/3 innings.  He got the loss on a Carl Yasztremski homerun in the top of the 14th.
