Kyrgios has done it a few times

Occasionally others too

Mostly seen as clever as it only works when the returner is standing miles behind the baseline which is an advantage to them and helps stop them doing it.

Andy Murray on the underarm serve: I was thinking about using it again in the 3rd set but didn't. First time I've ever done it in a match and got the ace, so maybe I'll try again in the future against guys standing that far back.
