There is definitely some value in this line. Larcher de Brito defeated Sharapova at Wimbledon last year in straight sets. Radwanska has struggled against some of the game's "screamers" in the past and let it get to her, and Larcher de Brito is probably worse than Azarenka and Sharapova combined.
Get it in soon, cause this match follows the Hewitt Jancowicz match.
