I'm not a big tennis fan. But while flipping channels this Sunday, I saw Serena Williams hit tennis balls over 120 miles an hour in her Wimbledon win.

My son and I commented how impressive that was, and how much the game has changed.

Then, I saw this clip of Dustin Brown playing. Wow! Click it, and watch it. 

 

 

It surprised me by how fast the game was played, and how the ball's path seemed to bend. More importantly, one of the best players in the world seemingly had no response.

Even though Brown was defeated in the third round of the tournament … Sometimes the game changes right before your eyes.
