When you've got Woodruff, Burnes, Peralta, Chacin, and Guerra in the pen and the first 6 Dodgers are batting right handed, you are absolutely correct. One of those arms should be pretty close to ready to go if Gio gets in trouble. If the first 2 guys get on, you make a change. If 2 of the first 3 batters get on, you make a change. It's the right thing to do.
