The Phillies are going to use much of September trying to figure out what they have in the bullpen — not just who they have, but how they can use them. Tanner Banks has been thrown into increasingly chaotic situations and just keeps passing the test. Orion Kerkering has been given new challenges and it hasn’t gone smoothly. Jhoan Duran is still the ninth-inning guy because that’s how the Phillies want to use him in October, and there’s not much reason to mess with him right now.
There are new faces. David Robertson has performed amicably. Tim Mayza might be something.
