Except Margot is in the lineup now, the LH batter is gone and you're basically guaranteeing Margot will face a RHP twice. They pull Wallner and Julien early so the only advantage is the switch hitters Castro, Lee and Santana get to hit LH. The opposing manager is not going to keep a lefthanded reliever in the game for multiple innings. Wait him out and the LHP will be gone anyway.
