Is Game 2 of NLCS a must-win scenario for Diamondbacks with Merrill Kelly on the mound?

After losing Game 1 of the NLCS, history is not on the Arizona Diamondbacks’ side when it comes to winning the series. But the Snakes do have “The Mainstay” Merrill Kelly on the mound, who has been outstanding this season. Can the D-backs rob the Bank and steal one from the Phillies at home? And do they need to win Game 2 against the Philadelphia Phillies and Aaron Nola in order to have a chance in this series?
