I was excited to contribute to this fascinating article by @Mashable's Patrick Kulp on why Serena Williams isn't landing more big time sponsorship deals.

"As Serena Williams swats and backhands her way towards sports history at the U.S. Open this week, controversy has cropped up over whether she is getting a champion's payday that's worthy of her performance on the court.

The fact at the heart of it all: Maria Sharapova, the tall, blond Russian superstar whom Williams has bested in 16 out of 17 of their matches, earned $10 million more in endorsement deals last year than Williams, according to Forbes' data."
