This person has a front-row seat to the trial of the century — but can’t keep their eyes open.

The judge in Joaquin “El Chapo” Guzman’s trial on Wednesday said he’s going to have to admonish one of the jurors — because the panelist keeps dozing off.

“They’ve all been doing really — well, except one juror,” Brooklyn federal Judge Brian Cogan said while the jurors were out of the courtroom.

Cogan didn’t identify the sleepyhead in question — but one man, the first alternate juror, has been seen nodding off in the courtroom on a daily basis, even as the rest of the room sits riveted to testimony about multimillion-dollar drug deals, alleged presidential payoffs, and the drug lord’s private zoo.

The judge noted that he’d generally reminded the court several times during the trial that it’s important to pay attention, but he’d been trying to avoid singling out the slumbering juror.

Cogan said he or Courtroom Deputy Melonie Clarke would speak with the person and put “a little more emphasis” on the importance of staying awake.
