Cyclist Horner of U.S. Takes Overall Lead in Italy CHIETI, Italy (AP) - Chris Horner of the United States took the overall lead after the fourth stage of the Tirreno-Adriatico race Saturday. The 40-year-old Horner holds a seven-second lead over Roman Kreuziger of the Czech Republic, with Cameron Meyer of Australian third. Peter Sagan of Slovakia used a late burst of speed to win the grueling fourth stage of the weeklong event. He clocked a marathon-like 7 hours, 24 minutes, 50 seconds over the 156-mile leg from Amelia to Chieti, which featured a short but steep uphill finish. Kreuziger crossed second and Sagan's Liquigas teammate Vincenzo Nibali was third. Danilo Di Luca, the 2007 Giro d'Italia champion, finished fourth. Horner, who rides for the RadioShack-Nissan team, was fifth. "The legs are good, so certainly I have a shot at winning," Horner said. The stage 5 Sunday features two difficult climbs and another uphill finish following a 122-mile route from Martinsicuro to Prati di Tivo. The race ends Tuesday with a 5.78-mile individual time trial in San Benedetto del Tronto on the Adriatic coast.
