Contreras went into his slide before getting to the bag, went directly into the bag, didn’t slide through the bag, kept his back foot on the base, and didn’t have his spikes up above the fielder’s knees.
The TV guys are right, Contreras has nowhere else to go within the rules, so Hamilton should’ve not been in front of the bag.
Aggressive play, but hardly dirty or one that he would get called out for under the rules.
