It's over, Crawford retained his belt.
Kava was only good in the first 3 rounds, and after that, Crawford took over, round ninth stoppage. Would like to see Crawford vs Porter or Crawford vs Spence, it will be explosive, lol.
It's a tactical fight for Crawford here, he have hit with an overhand right in the third round if I'm not mistaken but the referee rule it out as a slipped. But after that, he has read Kavaliauskas, just looked at how he counters him with his lead right. It was just a jab, but it was that accurate.
He needs to really go and fight the big boys on the other fence Crawford vs Spence is what boxing fans wanted to see.
I wouldn't say that this is a tactical fight, this is more of a cherry pick by Bob Arum to look like Crawford is really that good. As @Baofeng has pointed out, good for three rounds and after that Crawford shows us what he is the champion and elite level.
Kavaliauskas is not on Bud Crawford's level, in paper it looks like he has a chance, but we have seen Crawford psychically breaking him down. He was supposed to be the stronger of the two, but Crawford just push him. And when the pressure starts to mount, Crawford did go for the kill.
