Playing doubles, recreation level. The server's first serve is a few feet out to the side. My teammate receiving strikes the ball back. I start getting ready for the second serve, I figured the ball was so far out, no need for a call. I get confused, because it looked like my teammate was not sure if it was in or out(no idea how). The opponent starts running to make contact at the ball. As his ball starts to land, I saw something like, "whoaaa, sorry that was way, way out, I didn't call it because I though it was obvious". The servers partner clearly saw it way out as well. Second serve was a double fault. At that point the other team starts complaining. what is the correct course of action for this situation? Should it have been two first serves? This group I play with FREAK out if you ever strike a ball back and call out at the same time. Which is another question I have, can I strike the ball and call it out? I always try to play the correct call, but I can't watch a ball to see if it will land in then start swinging. If it is a first serve and is close to the line I have to be swinging. thoughts on this?
