St. Louis Cardinals designated hitter Willson Contreras flew into a rage Monday night after being called out on strikes, going after the home plate umpire and eventually flinging a bat that hit his own coach.

The incident stemmed from a borderline pitch that umpire Derek Thomas called strike three on Contreras in the bottom of the seventh inning.

As Contreras was walking back to the dugout, he apparently said something that got him ejected. Cardinals manager Oliver Marmol came out to argue as Contreras turned around and became more animated in his protests. Marmol ended up having to hold his player back until other Cardinals coaches stepped in.

As they were walking off the field, Contreras, still holding his bat, flung it toward the field – stiking hitting coach Brant Brown in the arm.

Afterward, Contreras said he didn't understand why he was ejected in the first place.
