Consecutive seventh-inning homers by Jack Clark and Mike Ivie helped the San Franciso Giants survive three consecutive home rums by Philadelphia's Mike Schmidt and record an 8-6 triumph tonight over the Phillies.

On April 17, 1976, Schmidt joined an elite club of only 10 players to hit four homers in one game when he accomplished the feat against the Clubs in Chicago. Actually, Schmidt made it four straight tonight counting one he hit in his last at-bat Friday night.

Schmidt's three-run shot gave the Phils a 5-3 lead in the third inning.

Schmidt made it 6-4 in the sixth with a drive over the center-field fence aginst reliever Pedro Borbon (4-2).

"(Pictcher Pedro) Borbon got the slider a little outside. If it would have gotten a little more of the plate, I might have a nailed it."
