Re: 1997-1998 Juniors: Wiersholm, Nava, Kozlov, Tiafoe, Mmoh, Blumberg, Ponwith, etc.
Qualifier Michael Mmoh of the United States won the singles and doubles titles at this week's ITF Grade 4 in Guatemala, beating No. 2 seed Sebastian Penaloza of Chile in the final. In addition to defeating the No. 1 and No. 2 seeds, the 14-year-old, playing in just his sixth ITF event, beat American Henrik Wiersholm, last week's Grade 4 winner, in the semifinals. Mmoh also won the doubles, teaming with Thomas Adriano Tenreiro of Venezuela.
