The D-backs let Matt Koch leave the dugout a little too early and it led to a very awkward moment

When Matt Koch arrived at Chase Field on Friday after being promoted from Triple-A Reno, he was more than ready to make his start on the mound for the D-backs. However, his teammates were more than ready to have a little fun with him.
Koch was seen standing alone atop the D-backs' dugout when he ran out on to the field before the rest of the team prior to their matchup with the Padres:

Crickets.
It appeared the guys let him leave earlier than the rest of them so he was forced to run out on his own. Koch was smiling, but you can see he was a bit unsure about what was going on. 
Nevertheless, Koch finished the night giving up just two hits and two walks with four strikeouts in six innings.
