Cliff Pennington made MLB history in Game 4 of the ALCS. Dan Hamilton USA TODAY Sports

Down 13-2 with men on first and second in the ninth inning of ALCS Game 4, the Toronto Blue Jays knew their loss was pretty much sealed.

Instead of burning an arm against the Kansas City Royals, the Blue Jays did something that has never been done in a postseason game in MLB history -- they put in a position player to pitch.

Cliff Pennington entered the game and flashed a pretty healthy fastball, causing the Toronto fans to erupt in applause.

He went on to give up back-to-back singles, pushing the score to 14-2, but he induced a pop fly from Ben Zobrist to end the top half of the inning.

Of course, Twitter collectively lost its mind.

The Royals went on to win the game, moving ahead 3-1 in the ALCS.
