Porter and Corporan continued to argue in the dugout before Jose Altuve stepped in and created some space between the two.
"It's just the heat of the game," Corporan said. "Things happen in baseball. We talked about it, and it's fine. We just turned the page and are trying to win today."
On Friday, Porter declined to elaborate on the incident, which was caught by TV cameras.
"What happens between me and my players during the game will always stay between me and my players," he said.
Corporan said he plays the game with passion by nature.
"I get fired up," he said. "That's just my nature. I like to win and I want to do well for my team. We talked about it in the dugout and now we're straight. Things like that happen."
