How Fast is the Move "Play Rough", how long does it take to do damage?

I tried Soloing a Granbull yesterday with Snarl/Close Combat and I tried a few times but she wouldnt go down, she had 3% HP left when the battle ended, anyone hnow how fast of a move Play Rough is?

Depending on how strong the Pokemon is, they can use it real fast. I’ve been surprised by more than a few Slakings and Wiggly Tuffs by it.

2.9s, thats what the database is for
