Thailand’s Yuttana Charoenphon overturned the loss of the first set to topple top seed Ryoma Matsushita 5-7, 6-3, 6-3 in the boys singles final of the ITF Junior Tennis tournament at the National Tennis Center yesterday.

The second-seeded Charoenphon led 5-3 in the first set only to see his Japanese rival win four games on the spin to take the first set.

But the effort clearly told on Matsushita, who quickly went down a couple of service breaks in the second, and he ran into further trouble in the third as the temperature got hotter, as did the intensity of battle.

But Yuttana, who trains at the Paradorn Srichaphan Tennis Academy in Bangkok, had no problems dealing with the heat and humidity and kept at full throttle to wrap up the contest.

Earlier in the semifinals, Matsushita beat compatriot Kei Manaka 6-4 6-4, and Charoenphon got past Xian Yao Zhou of China 6-1, 6-3.

In an all-Korean final, sixth seeded Bo Young-jeong beat unseeded Ryeong -gyeong Park 6-3, 6-2 to clinch the girls singles title.

When Leng Sarinreach defeated Rongjun Chen of China 6-3, 7-5 in the first round of the boys singles qualifiers to take a shot at the second week of ITF Junior Tennis action, which starts today, hopes were high in the Cambodian camp of at least one player making it to the main draw.

But his eagerly anticipated clash with Keiju Miyake was sadly one-sided in favour of the Japanese top seed, who won 6-2, 6-0, not giving Sarinreach enough pace or space to fight.

All other Cambodian players lost in the first round of the qualifiers.

Ye Kim Hoy lost to Nathan Jattavapornvanit of Thailand 6-0, 3-0 (retired), Tep Timothy lost to Indonesia’s Daniel Gunawan 6-1, 7-5, Khleang Ponlok lost to Kita Shoma of Japan 6-0, 6-0, Leap Sovannary lost to Kim Min-soo of South Korea 6-0, 6-0, Nolane Cerezales lost to Thailand’s Chanbubpha Songrit David 6-0, 6-0, Ran Chamroeun lost to Hamdan Muhammad Aiman of Indonesia 6-0, 6-2, and Van Seth lost to Kato Kodai of Japan 6-0, 6-0.
