The Padres might be stewing about this one all offseason.

With their season at stake during the decisive wild-card Game 3 against the Cubs on Thursday, Xander Bogaerts stepped up in the ninth inning following Jackson Merrill’s leadoff homer and had worked the count full.

He took what appeared to be a pitch well below the zone from Chicago reliever Brad Keller, which would have meant a walk.

However, home plate umpire D.J. Reyburn disagreed, calling the pitch a strike — as a result, Bogaerts was not granted first base and became the first out of the inning’s final stretch.

Bogaerts turned to Reyburn and crouched down in disbelief, while Padres manager Mike Shildt emerged from the first base dugout for a discussion, but it was to no avail.

Making matters sting more for San Diego is that the next two batters reached base on plunkings.

But they failed to get any runs in after a groundout and a flyout ended their season.

If Rayburn’s call happened in 2026, the Padres would have likely been able to challenge the call with MLB’s incoming automated ball-strike system (ABS) that would allow a pitcher, catcher or batter to flag a home plate umpire’s decision and put it to a quick video review.

With no ABS, though, the Padres were out of luck, and the Cubs are advancing in the playoffs for the first time since 2017.

The Cubs will face the NL Central rival Brewers in the best-of-five NLDS on Saturday.
