Polish qualifier Janowicz into Paris Masters semis

PARIS (AP) - Polish qualifier Jerzy Janowicz continued his remarkable run at the Paris Masters on Friday, reaching the semifinals when eighth-seeded Janko Tipsarevic retired while trailing 3-6, 6-1, 4-1.

Janowicz saved one match point in his third-round win against Britain's Andy Murray on Thursday and had broken Tipsarevic for the second time in the third set when the Serb called for a trainer.

Tipsarevic briefly continued and Janowicz was ahead 40-0 on his serve when Tipsarevic waved his racket to indicate he was stopping, drawing jeers from the crowd at the Bercy Indoor Arena.

The 69th-ranked Janowicz faces Gilles Simon, who is also unseeded, in the semifinals. The Frenchman earlier beat fifth-seeded Tomas Berdych of the Czech Republic 6-4, 6-4.
