Tennis Player Nails Teammate in the Skull with a 93MPH Serve [VIDEO]

At Wimbledon this week, a 22-year-old tennis player from Latvia hit her mixed doubles partner with her serve . . . TWICE.

Her partner is a 42-year-old guy from Sweden. On Monday she nailed him in the back. Yesterday she crushed the back of his skull on a 93mph serve.
