KUALA LUMPUR: Malaysian sprinter Nazmizan Mohamed was way off his personal best in the Houston Open on Wednesday.
Nazmizan, who won the 100m and 200m golds at the Vietnam SEA Games in December, could only manage 10.58 in the men's 100m, way off his personal best of 10.38.
The 23-year-old Terengganu sprinter will compete in another meet next week in the United States in his bid to qualify for the Athens Olympic Games in August under Category B. The qualifying mark is 10.28 and he has until the end of this month to qualify for the Games.
Nazmizan also failed miserably in his first competition in the US, clocking 10.85 at the Baylor University Championships in Texas.
Roslinda Samsu, meanwhile, became the first Malaysian women to clear the 4m barrier in the pole vault last week. She shattered her national record by clearing 4.05m in a competition in Texas last week to erase her previous mark of 3.91m set last year.
Roslinda, however, could only manage 4m in the Houston Open on Wednesday.
Three other national athletes also failed to perform well in the Houston Open.
Mohd Syahrul Amri Suhaimi, who bagged the men's long jump gold with a 7.65m effort in the SEA Games, only managed 7.16m. Mohd Hazuan Zainal Abidin, also a long jumper, cleared 6.90m.
High jumper Ahmad Najwan Aqra, who has a personal best of 2.10m, could only manage a poor 1.90m.
