After winning her second-round match Thursday on Court 2, four-time Wimbledon champion Serena was asked about being put in that venue, where five-time champion Venus won Monday. Each has also played one match on Centre Court this week.
"They like to put us on Court 2 -- me and Venus -- for whatever reason," Serena said. "I haven't figured it out yet. Maybe one day we'll figure it out."
Told of Serena's comments, tournament spokesman Johnny Perkins said there was no intentional snub, noting that several factors go into scheduling decisions, including TV broadcasting considerations, where players stand in the draw and what ticket-buyers want to see.
"I don't think it's anything deliberate, clearly," Perkins said. "It's a hugely complex jigsaw puzzle. Everyone probably looks at it from their own point of view, so she's obviously quite entitled to."
The Williams sisters have combined to win nine of the last 11 Wimbledon singles championships, including Serena's titles in 2009 and 2010.
"I don't really think about it. I don't make it a big issue," Serena said about the scheduling. "I think at some point, maybe I should."
Stacey Allaster, the head of the women's professional tennis tour, said in a statement: "Serena Williams is a four-time Wimbledon singles champion, the defending champion of Wimbledon and a 13-time Grand Slam singles champion. I share her disappointment. Scheduling decisions at Wimbledon are made by the All England Club and only they would be able to explain the rationale behind their decision for the scheduling of Serena's match today."
"Yeah," Serena said, "they're never moved across."
The Court 2 she played in Thursday was built before the start of the 2009 tournament and holds about 4,063 spectators -- 7,330 fewer than Court 1 and 10,916 fewer than Centre Court. For years before that, the name "Court 2" at the All England Club was assigned to a venue about half the size and a few minutes' walk away.
That old Court 2 was known as the "Graveyard of Champions" because of a series of surprise losses by top players -- including Serena against Jill Craybas in the third round in 2005. That particular match actually was originally scheduled for Centre Court but was shifted when others there went long. Jimmy Connors, John McEnroe and Pete Sampras -- in his final match at the All England Club -- all lost on the old Court 2.
After watching his daughter defeat Simona Halep of Romania 3-6, 6-2, 6-1 at the new Court 2 on Thursday, Richard Williams downplayed the issue of court placement.
"I can't say where she should be," he said. "I don't do the scheduling."
