When playing a game like tennis or badminton, it often happens that after a long rally, my opponent hits the ball so that it just goes out. In English, I would sometimes say something like "Close!" (not always; it gets annoying if you say it too much). What would the German equivalent be?
On a similar note, I will from time to time say "Gute Schlag!" or "Schöne Schlag!" if my opponent hits a good shot -- if that sounds ridiculous, it would be good to hear about that too ;)
