Immediately following a victorious match, players at the Miami Open usually spend some time signing autographs and mingling with fans. When Bethanie Mattek-Sands emerged from the grandstand court she was a completely different person than the one who had just been playing! Her face lit up when she saw spectators waiting to greet her. She was quick with a big smile, laugh, and happy to take selfies and interact with fans. Quite gregarious!
I particularly liked this interaction with a fan in a wheelchair. Bethanie squeezed her hand and chatted for a bit before moving along.
And this is Big John Isner signing autographs in the same area, just outside the grandstand court. Look at that smile! So nice. I'm not sure if you'll see this kind of close fan interaction with any other professional sport nowadays. I love this aspect of tennis -- hope it doesn't change.
