"The plate umpire appealed the check swing to me. I thought he went, so I called it a swing," Morales said, via MLB.com. "Check swings are one of the hardest calls we have. I don't have the benefit of multiple camera angles when I'm watching it live. When it happened live, I thought he went, so that's why I called it a swing."

Flores said after the game he didn’t think he went around.

"I don’t think I went. Every at-bat matters in a close game, but there are some things you can’t control," he said.

Ultimately, it was Cody Bellinger who gave the Dodgers the late-game heroics, singling home Justin Turner in the top of the ninth inning to give Los Angeles the 2-1 lead.

Pitcher Max Scherzer would make the final appearance and strike out Flores.
