The Chicago Cubs routinely made history all year long, but even as the postseason began on Friday they managed to do something that no team has done in 33 years.

In the top of the third inning, Conor Gillaspie reached base with a single to lead off the frame. As they’ve done a few times this season, the Cubs made a bit of a defensive shift to compensate for Jon Lester’s difficulties in throwing to first base, meaning that first baseman Anthony Rizzo had to put on a second baseman’s glove and stand next to the pitcher’s mound.

The strategy clearly worked, as David Ross picked Gillaspie off first base after a pitch-out by Lester, getting the Cubs out of a potential jam.

With the successful putout, the Cubs made some pretty cool history. According to Jeff Passan of Yahoo Sports, Rizzo was officially credited as playing second base when Ross picked Gillaspie off, making him the first left-handed player to play the position since 1983.

The last time that a lefty played second base was legendary Yankees player (and current Miami Marlins manager) Don Mattingly, who did it in a game during the 1983 season. The game was actually the continuation of a famous contested game, as it was the end of the infamous Pine Tar game that saw a home run by Hall of Famer George Brett overturned.

According to Joel Sherman of the New York Daily News, Yankees pitcher Ron Guidry also played center field in the infamous game, with manager Billy Martin seemingly thumbing his nose at Major League Baseball with his decision making.
