U.S. Open fans can't seem to get enough of practice.
That's right, practice.
In a new feature at Flushing Meadows this year, elevated stands loom over five practice courts and allow fans to see stars like Roger Federer and Serena Williams groove their strokes, tinker with strategy and sometimes bicker with coaches.
Hundreds of fans now sit where a huge privet hedge once shielded the courts, and there's even a massive tote board that advertises when players will be practicing. Since the tournament began this week, the stands have been mostly full.
The changes this year are a taste of $500 million worth of renovations to the tennis center over the next four years, including a retractable roof over Arthur Ashe Stadium and a new Louis Armstrong Stadium.
