Pretty sure they will run 6 until the ASG. Then drop to 5 after the break.
Joe believes that he is a starter that has been forced into the role that he is in. They should have kept Rosscup up to be the LOOGY and pushed Duensing into the long man role.
So with 6 guys it would be Lester, Hendricks, Montgomery, Butler, Arrieta, Lackey. After the ASG most likely Butler goes to AAA. I'm thinking with Montgomery not there to pick up his 6th and 7th inning will not bode well in his game. Joe has been yanking him around 60-70 pitches so I'm thinking it has more to do not trusting him going up against a line up that many times. Most likely 3rd time pulled.
