In the previous post about the two-run reliever with the three-run lead, the Fangraphs readers leaned 80-20 toward “a run is a run”, compared to “he did his job”.

Let’s make this one similar, but tougher. We have our ace reliever entering the bottom of the 9th inning. This time, our ace reliever gives up a leadoff HR, followed by striking out the side.

We have two different relievers:
(a) we have Billy Wagner entering the game with a 2-run lead, and so, managed to squeak out of it to end the game. If you are interested, his team had a 90% chance of winning before he showed up. And the Astros won.

(b) we also had Trevor Hoffman face the same scenario with a 1-run lead. He leaves the game tied making the Padres go into extra innings, turning an 80% chance of winning into a 50% chance.
