Watch: Walker Buehler slams cooler, throws glove in Dodgers dugout following disappointing start against Padres

LA Dodgers ace Walker Buehler had seen better days on the mound than in the second innings of the National League Division Series (NLDS) Game 3 against the San Diego Padres. His frustration broke out as he slammed in what appeared to be a cooler and a glove. He expressed frustration over what unfolded in the six-run second innings.

It's never a great moment to lose cool in the game. But it was always coming with the postseason at its peak and the Padres on the Dodgers's throat since the Game 2 blowout loss.

What happened in the second inning?

Walker Buehler retired three straight hitters in his first postseason start. In the second innings, however, everything went against him.

Manny Machado hit a single. It was followed by a ground ball by Jackson Merrill to first, which could have been a double play. However, Freddie Freeman's throw from first to Miguel Rojas ended up hitting Machado, who was on the base path, as the ball ricocheted to left field. This also allowed Machado to advance to the third.

Another fielding mistake occurred after Xander Bogaerts grounded out a short hop to Rojas, who made a mess of a play after he could not record even a single out on a potential double play opportunity. Meanwhile, Machado scored from third.

This meant there were two opportunities for the Dodgers to end the inning, but their blunder allowed the Padres to score in a bundle. David Peralta's RBI double led to two runs being scored off Buehler. A sacrifice fly from Kyle Higoshioka drove in another run.

Finally, Fernando Tatis Jr.'s two-run home run was the cherry on top, as the Padres scored six off Buehler in the second inning.

Walker Buehler all smiles after the Dodgers responded with four runs

The Dodgers' offense didn't take too long to make easy of the five-run deficit.

Against Padres starter Michael King, Miguel Rojas, Shohei Ohtani, and Mookie Betts hit three straight singles to load up the bases for Freddie Freeman. However, the Dodgers first baseman retired on a flyout.

Teoscar Hernandez didn't need a second invitation to pounce on a high 85 mph pitch from King to send the ball distance as he recorded a grand slam and put the Dodgers right back in the game, cutting the Padres' lead to 6-5.

Of course, Walker Buehler was all smiles after that.
