SOCCER—NASL: The race for the Southern Division lead remained tight, with Tulsa finishing on top for the third straight week. The Roughnecks were one-and-one, losing 2-1 to Toronto but recovering to beat Chicago by the same score. In that game Tulsa led 1-0 after Ron Futcher's goal in the first half until three seconds were left in regulation play when the Sting's Karl-Heinz Granitza scored from 15 yards to tie the score. Laurie Abrahams, Njego Pesa and Barry Wallace all scored shoot-out goals to give Tulsa the win. Fort Lauderdale, now four points out of first, pulled itself out of third place to its highest standing of the season with wins over Toronto (2-1) and Tampa Bay (3-2). Third-place Team America fell twice, to the Cosmos (4-0) and Toronto (2-1), but its 8-7 record, still the best in the division, makes it a club to reckon with. In the Eastern Division, the Cosmos stayed on top by three points despite a 2-0 loss to Vancouver. In the Cosmos' triumph over Team America, Giorgio Chinaglia sustained a pulled left hamstring, which will force him to the sideline for at least two games. Meanwhile, their victory over the Cosmos and a 5-3 win over Montreal boosted the Whitecaps' lead in the Western Division to 45 points (page 56).
