Francis Tiafoe kicked off 2012 by capturing singles titles at two of the world's most prestigious events for players' 14-and-under. Tiafoe, a 14-year-old from College Park, Md., first won the AEGON Junior International in Bolton, England, by defeating fellow American Michael Mmoh, 6-3, 6-3, in the final. The following week, he beat William Blumberg in another all-American boys' singles final at Les Petits As in Tarbes, France, where he also claimed the doubles title with partner Mmoh. Past Les Petits As champions include Rafael Nadal, Michael Chang, Kim Clijsters, Martina Hingis, Richard Gasquet, Dinara Safina, Juan Carlos Ferrero and Bethanie Mattek-Sands.
