PENA CABARGA, Spain — Vasil Kiryienka of Belarus broke away before a final grueling ascent to win the 18th stage of the Spanish Vuelta Thursday, while overall leader Vincenzo Nibali saw his advantage over Christopher Horner cut to three seconds with three days to go. Kiryienka finished in a provisional time of 4 hours, 46 minutes, 48 seconds following a 186.5-km route starting in Burgos and passing over four major climbs before a final uphill push to the finishing line at Pena Cabarga. The 41-year-old Horner used an impressive burst to pull away from Nibali over the final 200 meters where the slope reached 20 degrees, gaining 25 seconds on his rival. — AP
