Hernan Iribarren of the Cincinnati Reds and Manny Pina of the Milwaukee Brewers engaged in a pre-game standoff after the national anthem.
Both players stood with their hats and hands over their respective hearts as their teams walked back into the dugout before the game.
Pina moved first, which gave the Reds the victory.
Watch the odd interaction below:
Last year, Brewers third base coach John Shelby was locked into a battle with Todd Frazier, which the former Reds third baseman lost.
