the server
Advantage
The ad side of a tennis court is the players left side. Or the opponents right side.
It is either ad in or ad out. If the server won the point it is ad in and if the returner won the point then it is ad out.
When serving or returning, there is a deuce side and an ad side. The deuce side is on the right, the ad side is on the left.

advantage in favor of the server in tennis; advantage in favor of the receiver. Terms used after a deuce, i.e., 30-all.
Believe it or not!
after you get deuce and the server wins the point. You call it 'ad in'
