Sam should be able to win this in straights.
Sam has the weapons while Jamea has the speed but Jamea's speed right now is negated by her previous hip injury.
She'll give it her best try but I'm sure Jamea is waiting for the grass season.
Sam should win this one...because Jamea is out of form at the moment..but she is a better clay player then Sam and Jamea also hasnt lost a major in the first round since 2005. So it will be a good match im sure.
