Alejandro De Aza, who was called out on strikes in the second and the fourth, had argued at the end of the previous at-bat with Kulpa on that second called third. But De Aza was pulled away by Flowers and manager Robin Ventura and able to stay in the game.
"Obviously, I strongly disagreed with the call he made. A little heated at the moment," Flowers said. "He might have been a little heated, too, from whatever else transpired earlier in the game. It is what it is. [Starter Jose Quintana] did a good job and the bullpen did a good job."
Flowers has no worries about working with Kulpa in any upcoming games following Monday's argument.
"That stuff happens, you know. I see it from both ends, too," said Flowers, who added that he didn't say much before the ejection and didn't use profanity. "You see some that are generous and some that you disagree with.
"It's a bunch of human beings out there playing a game and doing a bunch of different things. I don't think he's that kind of a guy where it's going to be an issue next time we work together. I said my piece and that was it."
