HOCKEY—Philadelphia defeated Minnesota 5-3 in Bloomington, Minn. to take a 2-1 lead in their best-of-seven National Hockey League semifinal series. Left Wing Bill Barber scored four goals to pace the Flyers. The teams split Games 1 and 2 of the series in Philadelphia, the North Stars winning the opener 6-5 as Steve Christoff, a hero on the U.S. Olympic team at Lake Placid, had two goals to establish a record for playoff goals by a rookie (8). The Flyers recovered to win the second 7-0. Though Philadelphia had the league's least productive power play during the regular season, four of the Flyers' first five goals were scored when the North Stars were down a man. After not playing for nearly three weeks, Flyer Goalie Phil Myre returned to stop 27 Minnesota shots. In the other semifinal, the Islanders took a 3-0 lead over Buffalo, winning by scores of 4-1, 2-1 and 7-4 (page 52).

HORSE RACING—GENUINE RISK ($28.60), ridden by Jacinto Vasquez, won the $339,300 Kentucky Derby at Churchill Downs by a length over Rumbo, to become the first filly in 65 years to win the event. The 3-year-old was timed in 2:02 over the 1¼ miles (page 14).

Bold 'N Determined ($3.20), Eddie Delahoussaye up, won the $129,100 Kentucky Oaks for fillies at Churchill Downs by 1½ lengths over Mitey Lively. The 3-year-old ran the mile and [1/16]th in 1:44[4/5].

SOCCER—NASL: Seattle rode the stingy goalkeeping of Jack Brand to two more victories and a 22-point advantage over Los Angeles in the National Conference Western Division. Brand got his sixth shutout in seven games and Roger Davies had two goals and an assist as the Sounders beat San Jose 4-0. Earlier, Brand made David Nish's goal at 14:02 stand up as the Sounders defeated Portland 1-0. Not even the return of Forward George Best, who joined the Earthquake lineup two and one half months after recovering from yet another bout with the bottle, could save San Jose from another winless week. Besides the loss to Seattle, the Earthquakes fell 3-2 to San Diego when Leonardo Cuellar scored for the Sockers with three minutes remaining, and to Edmonton 4-2. Tulsa defeated Los Angeles 1-0 on a goal by Alan Woodward and retained a six-point lead in the ASC Central. Minnesota got its first victory, 2-1 over Atlanta, on a goal by Ricardo Alonso at 79:25. Toronto split a pair of games, beating Washington 1-0 to move within two points of the second-place Diplomats in the NSC East, and then losing 3-2 to New England before 4,264 fans in the Tea Men's 61,279-seat Schaefer Stadium. That was a healthy throng compared to the 254 fans, the smallest group ever to witness an NASL game, who saw New England win 3-1 at home against Memphis. The New England management was so grateful to the few fans who braved 40° temperatures and driving rains that it rewarded each one with a season ticket. Philadelphia won its first game, 1-0 over Chicago, but the Sting bounced back to defeat Vancouver 2-1 in a shootout. ASC Central leader Memphis beat San Diego, the ASC West leader, 1-0 on Paul Cannell's goal at 77:37. Tampa Bay defeated Portland by the same score.

ASL: Sacramento took a one-point lead over Golden Gate in the American Conference by defeating the Gales 1-0 on Malcom Filby's goal at 35:00. Earlier in the week Golden Gate got two goals from Mai Roche, including the game winner on a penalty kick three minutes into overtime, to beat California 3-2. Columbus split, a pair of games and retained its 11-point lead over New York in the National Conference. The Magic beat Cleveland 2-1, with George Dewsnip getting a goal and an assist. Cleveland had to play without Goalie Marine Cano and Defender Joe Howarth, who suffered severe cuts and bruises in a traffic accident en route to the game. Both men were in action, however, in the Cobras' next game. Not so lucky was Columbus Forward Bob Rohrbach. Rohrbach is in serious condition in a Columbus hospital, having collided with Cleveland's Alex Rosul and sustaining a concussion that kept him in intensive care for three days. Miami got its first points in a 1-1 tie with Cleveland. Cleveland also lost 1-0 to Pennsylvania, the Stoners' Paulo DaSilva booming in the game winner from 25 yards out with three minutes to play.

TENNIS—JIMMY CONNORS defeated John McEnroe 2-6, 7-6, 6-1, 6-2 to win the $250,000 World Championship of Tennis tournament in Dallas (page 57).

JACQUELINE GAREAU, 30, who crossed the finish line with a time of 2:34:28, was declared the women's winner.
