Radwanska reaches Tianjin final

Tianjin - Second seed Agnieszka Radwanska of Poland easily won her semi-final match at the Tianjin Open on Saturday, setting up a final that will pit her against unseeded Danka Kovinic of Montengero.

Radwanska, ranked sixth in the world, beat third seed Czech Karolina Pliskova in straight sets, 6-3, 6-1.

Kovinic, meanwhile, beat Bojana Jovanovski of Serbia 6-2, 6-7, 6-2 in over two hours of play.

The semi-final matches were played in extremely poor air quality, with government data showing levels of PM2.5 particulates - small enough to deeply penetrate the lungs - nearly eight times the maximum recommended by the World Health Organization in a 24-hour period.

The $500 000 WTA tournament has seen a run of upsets, the most spectacular when Italian top seed Flavia Pennetta, who won the US Open last month, went out to a player ranked more than 400 places below her, Ukraine's Lyudmyla Kichenok.
