Well, that was a stupid question. I will give you that. Thanks for the alert.

Short (two word) answer: Um, no.

Longer answer: As long as he faces at least one batter, and leaves the game trailing, and his team never ties the game or takes the lead, a pitcher can be charged with the loss.

He can walk the first batter of the first inning, be removed, and if that guys scores, the run is charged to him.

If the relief pitchers goes on to give up 9 more runs, and the score is 10-0, and the losing team comes back to make the final score 10-9, the first pitcher who only faced one batter and was charged with only one run is still the losing pitcher.
