So yesterday I was playing in a mixed match. First time partner whom I had never met. In the first set we down 4-1 losing her serve once. They had a chance to serve out the set at 5-3 and we broke the opposing guy's serve. He slammed his racquet and yelled and what not. I went onto to hold at 5-4 and we won the first set 7-5. Second set same thing. Down 4-1 and down a break. We break back and get to 4-4. He is serving and loses his serve. He absolutely melts down. He takes a ball hits it as hard as he can. It hits one of the lights and comes flying back in the court. I am walking to the side. He proceeds to take two balls and slam them across the court as hard as he can from inside the service line, nearly hitting my partner. I asked her if she was okay. She said yes. As he is walking by, I tell him that I don't care if he is angry but don't hit at my partner. He gets up in my face and says that they just gave the game to us. I said it wasn't my problem. This idiot walks to the other side picks up a ball and proceeds to hit it ass hard as he can at us. My back was to him, but he nearly hit my partner, and his partner in the face. I rushed the court got in his face, yelled some expletives at him, and was close to taking a swing at him. I told him he was done, that this match was over because I was closing it out. I went back to the other side and yelled out "5-4, serving to the d*uchebag, as loud as I could." We won the second 6-4. This guy was probably 55. After the match his son, who was probably 21, came up to me and apologized for his father, and said he was really sorry. Most of their team was apologizing the whole time, and said he was completely out of line. I told his son I was protecting my partner, and that it's a game. His partner was shaking afterwards and was very upset at the whole thing. He stormed off the court, threw his bag in his car, and then had a confrontation with his son. They then left. A couple of people on my team were surprised I didn't just hit him. He was a real jerk. He was the type of player that if I missed an overhead or hit a poor shot, would say "thanks for the gift." Just a poor sport all around. Anyone ever experience something so bad. I've played against players that have thrown racquets and slammed balls, but never this bad. I'm just glad we beat him.
