I don't like saving him until the end. If you do that, you don't even know if you're going to have the type of high-leverage situation that makes him so valuable in the first place. Bring him for the first high-leverage situation with a dangerous LHB at the plate. Most likely that will be a middle inning after Chacin allows a base-runner or two, but I wouldn't hesitate to bring him in a little earlier if Chacin struggles at all. Another advantage of using him early is forcing LAD to make a difficult choice. Do you PH for an LHB in the 4th or 5th inning and then have too many RHB's for Knebel, JJ, Soria, et al later in the game? I've always thought using LHP's on a predictable schedule negates a lot of the match-up leverage they can give you, whether it be using them as starters or closers or any predictable role in between. ETA: All depends on their lineup too, of course. Roberts can go this way: Pederson L (If his wrist is intact) Turner R Muncy L MM. R Bellinger L Taylor R Puig R Barnes R P Freese, Dozier, Kemp, Kike, and Grandal
