Patrick Mahomes was on hand to watch the Royals take on the Yankees in Game 3 of the ALDS and cheered emphatically after they tied up the game in the bottom of the fifth.

In fact, the moment went viral when TBS cameras caught Mahomes running up to celebrate in the face of a Yankees fan in the suite he was sitting in.

The Yankees fan, it turns out, was former teammate Gehrig Dieter, who played for the Chiefs from 2018-20.

Mahomes, the star quarterback of the Chiefs who has helped lead the franchise to three Super Bowl titles, leaped from his seat in celebration and then moved quickly over to Dieter, who had been standing at the other end of the suite.

Mahomes leaped into him and seemed to start jokingly yelling at him as Dieter laughed.

Dieter then pretended to put his fists up in a fighting pose before Mahomes turned away.

The former Chiefs player, however, probably got the last laugh, as the Yankees won 3-2.

Mahomes owns a small piece of the Royals, and it was clear that he wanted to be on hand for the game, though he suggested that it might cause a rift with his wife, Brittany.

“That’s the plan; I have to just – it’s [the] bye week,” Mahomes said recently, according to Chiefs Wire. “So Brittany’s vacation and me getting to the Royals game will feud for sure.”

The NFL star wasn’t the only Mahomes in the building on Wednesday night, as his brother, Jackson, was also there.

The two posed for a picture — both in Royals jerseys.

They’ll have to hope for a better outcome on Thursday night because if not, Kansas City’s baseball season will be over.
