SEMIFINALES EN "MARCHA" US OPEN TENNIS

(1) Serena Williams vs. (5) Li Na
Head-to-head: Williams leads 8-1

Renovations to Arthur Ashe Stadium won’t include barricades around the baseline, but Serena has spent this U.S. Open boxing in opponents with blueprint precision.
Playing oppressive tennis, the world No. 1 has denied opponents' access to angles, imposing gridlock on tennis' largest Grand Slam stage. Williams has permitted just 13 games in five tournament victories, racking up shutouts in four of the 10 sets she’s played, including a crushing, 6-0, 6-0 quarterfinal dismissal of Carla Suarez Navarro. Serena looks driven to successfully defend the U.S. Open title for the first time, and here’s the frightening thought: She hasn’t fully unleashed her imposing first serve to full force yet.
Beating Serena in a Grand Slam semifinal is as tough as scaling the Unisphere in a single bound: She is 20-3 in major semis, with her last loss coming to Kim Clijsters at the 2009 U.S. Open, when she imploded after being hit with a foot-fault call.
