Talk about Electric Youth… Luguelín Santos has raced his way to the medal podium at the 2012 Olympic Games.

The 18-year-old Dominican sprinter claimed the silver medal on Monday in the men’s 400 meter race, giving his country its second medal of the day after Félix Sánchez won a gold at the track earlier in the day.

Santos finished half a second behind another teenager competing in his first Olympics, 19-year-old Kirani James of Grenada. James coasted to victory in a time of 43.94 seconds.

Santos—who won a gold medal in the 400 meter at the 2010 Summer Youth Olympics and was the third fastest man this year in the 400 meter field-—was billed as James’s main rival in the final, but just couldn’t muster enough power to pull ahead.
