Juan Laporte retained his WBC featherweight crown with a 12-round split decision over previously undefeated Johnny de la Rosa in San Juan.

PRO FOOTBALL—USFL: Oakland lost to Philadelphia 12-6 on Monday, but a subsequent 17-16 win over Boston finally clinched the Pacific Division title for the Invaders. Before halftime it looked as if the Breakers might win when Kevin Shea's field-goal attempt was blocked and then picked up by Boston's Ben Needham, who ran 75 yards for a touchdown and a 10-7 lead. But the Breakers, battling for the league's wild card playoff spot, fell apart in the second half to give Oakland the win. In the Central Division, Chicago also had a chance to clinch a playoff berth but lost 34-19 to Michigan. The Blitz was bombed by Panther Quarterback Bobby Hebert, who was hotter than the 99° weather, completing 12 of 21 passes for 247 yards and five TDs. Now Chicago and Michigan are deadlocked with 11-6 records. With its playoff slot secure, Philadelphia amused itself by surpassing the pro-record 14-win season first set by the 1972 Miami Dolphins. The Stars finished the week at 15-2 by beating Birmingham 31-10.

SOCCER—NASL: Chicago beat the Cosmos 3-2, ending a streak of six Junes, totaling 25 NASL games in which the Cosmos hadn't had a loss at Giants Stadium. The Cosmos rebounded with a 2-1 win over Montreal, thanks to Angelo DiBernardo's first goal of the season 2:31 into overtime and no thanks to leading scorer Giorgio Chinaglia, who was in Rome tending to his newly purchased Lazio team. The victory put the Cosmos back on top in the Eastern Division after Toronto had pulled ahead by one point following a 3-2 win over Fort Lauderdale. The Blizzard then regained the lead by 4 points with a 5-1 win over Golden Bay. Vancouver drew the largest crowd (60,342) in Canadian soccer history, and the Whitecaps—specifically Peter Beardsley, who had two spectacular goals—rewarded all those onlookers with a 2-1 win over Seattle. Vancouver also beat San Diego 1-0 and Tampa Bay 4-1 to boost its winning streak to eight games and its lead in the Western Division to 41 points. Tulsa was first in the Southern Division after a 2-1 shootout win over Fort Lauderdale.
