Austin Riley hit a three-run homer off Jhoan Duran in the eighth inning Tuesday and Atlanta rallied past Philadelphia 5-3 in the opener of the Phillies Braves Wild Card Series. In a best-of-three, that is the whole ballgame in one swing: the Phillies now have to win Wednesday afternoon in Atlanta or their season is over.

The decision behind it is the part people will chew on all winter if this goes wrong for Philadelphia. Don Mattingly wanted his best reliever on the mound as early as he could get him there. That is the modern October orthodoxy, and it is not a crazy thought. You do not save your closer for a ninth inning you may never see.

Why did Don Mattingly use Jhoan Duran in the seventh?

Because the leverage was in the seventh, or at least Mattingly read it that way. An All-Star closer is your best arm whether the scoreboard says 7 or 9, and managers have spent the last decade learning that the highest-stakes outs do not always come last. Get the best guy to the biggest moment. The logic is clean.

The execution is where October collects its rent. Asking a closer for a six-out save is asking him to face hitters he has already shown, in a second inning of work, with his fastball a tick off where it started. Riley got that second look. He did not miss it.

That is not a criticism of the process so much as a reminder of what the process costs. When you stretch your best arm, you are spending an inning of certainty to buy an inning of coverage, and sometimes the bill comes due in the eighth.

checked the almanac: kevin cash pulled blake snell in the sixth of game 6 of the 2020 world series with a lead and got buried for it, and grady little left pedro in the eighth of game 7 in 2003 and got buried for that. same October, opposite sins. the manager who touches the ball last owns the loss. always has.

What Game 1 means for the Phillies Braves Wild Card Series

Philadelphia loses more than a game here. It loses its bullpen script. Duran threw in a high-stress spot Tuesday, and whatever Mattingly wants to do Wednesday, he has to do it knowing his best arm has innings on him. In a best-of-three there is no tomorrow to reset with. There is only the next nine.

Atlanta, meanwhile, gets the thing you cannot buy in a short series: belief that the other guy's best pitch is hittable. Riley took the Phillies' most trusted arm deep with the game on the line. Every Braves hitter who walks up Wednesday has that in his pocket.

There is history sitting underneath this, too. Philadelphia knocked Atlanta out of the Division Series in back-to-back Octobers in 2022 and 2023, and those series are still live tissue in this rivalry. The Braves have been waiting a while to do this to the Phillies rather than the other way around. They got a start on it Tuesday.

What comes next for Philadelphia

Game 2 is Wednesday at 2:00 PM ET in Atlanta, and the Phillies are playing to survive it. Everything I want to watch is bullpen related: how early Mattingly gets somebody up, whether Duran is available at all, and which arm he trusts in the seventh if the answer is no. A manager who just got burned going to his best guy early has to decide, in about eighteen hours, whether he believes in the idea or in the outcome.

Those are different questions. The good ones know it.
