Wimbledon: Jamie Murray through as partner Soares hits out at umpires
Bruno Soares believes overly-officious umpiring is threatening to take emotion out of the game.
The Brazilian and his partner Jamie Murray reached the quarter-finals of the men's doubles with an epic 6-3 7-6 (7/3) 4-6 4-6 16-14 victory over Mate Pavic and Michael Venus.
Soares was unhappy to be given a warning for racket abuse late in the fourth set.
He said: "I'm pretty quiet, I'm pretty calm, I don't do much. I rarely get warnings. I was a bit frustrated that game because we had 0-40 to break back in the fourth and I threw my racket.
"Flat out, didn't damage the grass, I didn't say anything, just walked to the chair, and she gives me a warning. I just think it's unnecessary.
"If it's someone with a temper, they wait a little bit to give the first warning because they know it's going to happen, and they don't want to deal with the second warning and things like this. I feel like with me, I get a warning right away."
There have been a number of incidents of clashes between players and umpires.
Viktor Troicki was fined $10,000 after a rant about an overrule while Marcel Granollers and Pablo Cuevas staged a sit-down protest after they were given a second warning and a point penalty in a doubles match. Their first warning came after Cuevas threatened to urinate into a ball can having being denied permission to go to the bathroom.
Fines have been very steep, particularly for those players who have damaged the grass by smashing rackets, with Heather Watson losing nearly a third of her prize money.
"I think they're taking it to the extreme," said Soares. "I don't know if it's a tournament of the umpires.
"I kind of like people with temper, people like Andy (Murray) and Nick (Kyrgios), they bring excitement to the game. It's different, it's better. So if they keep that strict it's tough."
Murray and Soares were relieved to make it through to the last eight having led by two sets and had chances to win on Monday before the match was postponed for the night at 13-13.
The pair won their first grand slam men's doubles title in their first major tournament together at the Australian Open in January, which helped Murray climb to world number one.
He reached the Wimbledon final last year with former partner John Peers but lost to Jean-Julien Rojer and Horia Tecau.
"We're just glad to get through," said Murray. "We were annoyed at ourselves last night for not finishing the match and it was stressful because those guys just hit everything as hard as they possibly could every single shot."
