A judge ordered Houston Rockets center Akeem Olajuwon to pay $1,500 a month and $10,000 up front in child support payments to his former fiancee. State District Judge Norman R. Lee made the order Friday. Lita Spencer was asking Olajuwon for $4,500 a month and a $100,000 lump sum to take care of the couple's 5-month-old daughter.
