Genoni Martinez scored the game-winning 3-pointer at 8:37 of the fourth quarter, lifting Monterrey La RaZa over the visiting Blast, 7-6, Sunday night. The loss dropped the Blast (5-4) into a tie for first place in the Major Indoor Soccer League with the Rockford Rampage, which swept the Milwaukee Wave, 10-7 on Saturday and 7-6 on Sunday. Denison Cabral gave the Blast a 4-0 lead by scoring at 9:15 of the first quarter and 11:26 of the second, but La RaZa tied it in the third period on goals 15 seconds apart by Hector Vallejo and Mark Ughy. After Martinez's game-winner, the Blast pulled to within 7-6 at 13:28 on a sixth-attacker goal by Giuliano Celenza. The Blast, which played without Machel Millwood and Scott Buete, who stayed in Baltimore with injuries, will be at Milwaukee Saturday before facing the Wave at home on Jan. 30.
