That’s what it comes down to. The Diamondbacks absolutely control their own destiny, and just need to win one of the three games in this final series against the Astros, to guarantee themselves a wild-card spot. Of course, there are many other scenarios which could still come to pass. Even if the D-backs qualify tonight, it’s possible we may not know who they play in the wild-card round, until the Marlins finish their interrupted game in New York on Monday afternoon. But I’d certainly rather get the fundamentals out of the way as soon as possible. My fingernails might not be able to stand a full three days of nervous tension, especially as our opponents this weekend also have everything to play for.
