St. Louis Cardinals manager Mike Shildt was so happy his team is moving on to the NLCS that he couldn’t stop swearing.

In a video that surfaced online Wednesday night after the Cardinals’ 13-1 Game 5 win over the host Braves in Game 5 of the NLDS, Shildt was seen giving a fiery, expletive-filled speech to his team.

“The [Braves] started some s–t. We finished the s–t,” Shildt says in the video, which outfielder Randy Arozarena later acknowledged he posted. “And that’s how we roll. No one f–ks with us ever. Ever. Now, I don’t give a f–k who we play. We’re gonna f–k them up. We’re gonna take it right to them the whole f–king way. We’re gonna kick their f–king ass.”

The video is no longer available on Arozarena’s Instagram account, but it gained traction on social media.

The 24-year-old Arozarena said in a statement that he was sorry for releasing the footage.

“I want to apologize to my teammates, manager, the Cardinals organization and baseball fans for the video I posted tonight after our victory in Atlanta,” Arozarena said. “It was a moment meant to be private. I made a rookie mistake by sharing it on my social media account.”

It was unclear exactly what Schildt was referring to when he said the Braves started something. It didn’t appear any media were present at the time he let it rip.
