For some reason, Craig decided to try and tag Baez instead of simply stepping on first base.
Recognising this, Baez started running back toward home plate, buying some time for the runner on second to sprint home to score.
Craig realises this too late and tries to throw home but the runner was safe, and the Pirates go down 2-0.
Even worse, Baez, who was never tagged, then sprints towards first base with no Pirates player covering the base.
The throw is eventually off target and Baez manages to make his way to second.
What made the whole thing even dumber was the fact that there were two outs, meaning all Craig needed to do was step on first base to end the inning and none of this would've happened.
To add salt into the wounds, the Cubs dugout showed no mercy after the play, with members of the team bursting out into cheers and laughter.
Slate sports writer Dan Kois called it "the absolute worst play I've ever seen in a baseball game".
Fans on social media echoed similar sentiments, with one saying "kick the Pirates out of the league".
"This may go down as one of the most boneheaded plays I've ever seen," said another fan.
The Pirates ended up losing 5-3.
