What are you supposed to do when your doubles teammate repeadily miss calls balls hit by our opponents as "out" when you clearly see them as "in"? The other team is staring at us and it puts me in a weird position. Do I overrule him or what? Any ball that was part in/part out he would call "OUT". Every serve they hit that struck the service line, he would also call as "out". This happened more than a few times and I had to say something. What would you do?
