Ehhh, I mean they had a 2 run lead in the 8th with the normal 8th inning guy pitching to hold the lead, so how they got there becomes irrelevant because they were in the spot you hoped they'd be in even in a normal situation. Keller didn't succeed in his part today.
This said, I dont care for bullpen games and I really dont see much of an advantage in using an opener.
