BUENOS AIRES — Boca Juniors have won the relaunched Copa Argentina with a 2-1 win over Racing Club in the delayed final to remain the only champion of the competition in its checkered 42-year history. Uruguayan forward Santiago Silva gave Boca the lead with a long-range shot against the run of play in the 21st minute and Lucas Viatri scored the second just after the hour in the neutral city of San Juan. Valentin Viola pulled one back for Racing Club in the 68th minute of Wednesday's match in front of a 35,000 crowd. The match had been due scheduled for June 23 but was delayed because of fixture congestion. — AP
