University of Illinois freshman Raymond Martin won his second
Martin rolled to victory in the wheelchair 400 at London's Olympic Stadium with a time of 58.54 seconds. Tomoya Ito of Japan was second in 1:00.4
The 18-year-old Martin, from Jersey City, N.J., had won the 100 meters Sunday.
"The 100 is not my best, to be golden is unbelievable," Martin said after that race.
The newspaper said he has been through 17 surgeries, ranging from hernia repair to deep sinus cleansing.
He competes in the T54 classification, which covers athletes with partial trunk and leg function.
