Slovakian rider Peter Sagan of the Liquigas team won the 68th edition of the Tour of Poland on Saturday, after taking second spot on the final stage. The seventh and last stage, run over 128 km, was won by Germany's Marcel Kittel of the Skil-Shimano outfit for his fourth stage win of the race. It was a dramatic final day on the race with Sagan finally edging out Ireland's Daniel Martin, of the Garmin-Cervelo team who had won Friday's penultimate stage, by just six seconds in the overall classification. "This is one of the greatest successes of my career," Sagan told the PAP news agency. "I had doubts over whether or not I would be able to get back the yellow jersey that I lost yesterday. "For me, the race was training for the Tour of Spain but to win it, that's not too bad." Stage 1. Marcel Kittel (GER) Skil-Shimano 2hr 50min 00sec, 2. Peter Sagan (SVK) Liquigas same time, 3.
