What if the Closer blows a lead of more than four?

Team A is leading Team B 8-3 with in the bottom of the ninth and there is no one on base. The closer is called to preserve the win. He is not in a save situation because the lead is greater than 3 runs, the tying run is sitting in Team B's dugout and he is not going to pitch more than three innings. The closer is having a bad day and he suddenly walks the bases loaded. Unfortunately there is no one behind him who is ready to go and it takes time to warm up another pitcher. Then the Closer walks in two runs before the pitcher in the bullpen is warmed up. The score is now 8-5. Unfortunately that pitcher never gets a chance to come into the game because the closer serves up and grandslam home run and Team B wins 9-8. The Closer is obviously charged with a loss. He or She cannot be charged with a blown save because the lead was more than 3 and the tying run was not on deck when he or she came into the game. So is this closer charged with something else. Blowing a lead when the team is not in a save situation is much more serious and incompetent than blowing a lead in a save situation.
