Romo (5-4) took the loss Monday, giving up the walk-off run to the Rockies in the bottom of the ninth inning. Last week manager Bruce Bochy said that he would use both Romo and Casilla in save opportunities going forward. While Monday's situation wasn't a save, it was definitely a high pressure situation and Romo faltered. This should further solidify Casilla's role as the primary closer going forward.
