 Day one action at the Wimbledon tennis tournament. Coco Gauff, who won the U.S. Open last September, closed out day one action on center court with a decisive victory over fellow American Caroline Delahaye. Last year, I lost first round here. It was a very tough moment for me, so I'm a little bit emotional just because it's been a long year, but it's incredible how I was able to turn it around.
