Things have gotten a little chippy between the Chicago Cubs and the Pittsburgh Pirates.

The series between the two got off to a rocky start when Cubs first baseman Anthony Rizzo made a controversial slide into Pirates catcher Elias Diaz at home plate.

During Monday's game, umpires ruled that Rizzo’s slide was clean, but the next day, Major League Baseball said that the slide was illegal.

After an uneventful game on Tuesday, the benches cleared during Wednesday night's contest.

In the bottom of the third inning, Pittsburgh starter Joe Musgrove was on first base after hitting a leadoff single, before Josh Harrison grounded to Chicago third baseman Kris Bryant, who fired to Javier Báez at second base.

Musgrove slid into second base, with his momentum taking him into Báez, who had a few words for Musgrove.

Musgrove turned back towards Baez, which prompted the benches and bullpens to empty.

No punches were thrown and order was quickly restored.
