Ninth inning against the Marlins; score was 5 Diamondbacks, 9 Marlins. When behind by at least 3 runs, the Diamondbacks have a big inning comeback to take the lead in an incredible 25% of their games with opportunities (see this AZ Snake Pit article). Would it happen again? I was overflowing with optimism.
The bottom of the order loaded the bases with no outs. The top of the order scored 3 runs, to reach a 1-run game, runners on first and third, one out (Marte missed a chance to homer for an exciting end to the game).
