Von Hayes highlighted a nine-run first inning with a record-setting two home runs last night in Philadelphia, and by the time the game was history, more records had fallen as the Phillies defeated the New York Mets, 26-7.

Hayes became the first player to homer twice in a first inning and helped the Phillies post the biggest run total by a National League team since the New York Giants beat the Brooklyn Dodgers, 26-8, at the Polo Grounds in 1944.

The 26 runs were the most in the 103-year history of the Phillies franchise. Included in their 27-hit total were a club-record 10 doubles. Hayes' feat of two homers in an inning had been accomplished 21 times previously in the major leagues, twice by Willie McCovey.

Hayes connected as leadoff hitter and added his first grand slam ever in an inning that also saw a triple by Rick Schu and the first of three doubles by Bo Diaz. The Phillies knocked out Tom Gorman (3-3), then took reliever Calvin Schiraldi for 10 runs on 10 hits to lead by 16-0 after two innings.

The 26 runs were the most ever against the Mets.

Winner Charles Hudson (2-6) gave up 13 hits in five innings as the Mets closed to 16-7 before Philadelphia made certain they lost the sixth game in their last seven.

The Phillies' 27 hits surpassed by one the team record set in a 26-23 loss to the Chicago Cubs in 1922. They also had a 23-8 victory over Pittsburgh in 1900 and in 1979 beat the Cubs, 23-22, as Mike Schmidt hit four home runs.

The run record for a major league game is 29 by the Boston Red Sox against the St. Louis Browns in 1950 and by the Chicago White Sox against Kansas City in 1955. The NL high of 28 was set by the St. Louis Cardinals against the Phillies in 1929.

Schmidt had a single and a two-run double in last night's seven-run second inning. The Phillies batted around again in the fifth and the seventh against Joe Sambito. Hayes had a bases-loaded walk to drive in his sixth run. He had come into the game mired in a two-for-33 slump.

"I had him leading off," said Manager John Felske, "because I wanted to give Jeff Stone a night off and I didn't want to mess with the lineup."

"After the first two home runs I didn't want to start swinging for the fences," said Hayes. "I had myself out of kilter and I didn't want to revert back."

The Phillies had 28 runs their previous 10 games. "Too bad," said Felske, "we can't go back and spread some of those runs and hits around."
