Mel Hall lined a three-run triple and Bill Buckner hit a two-run homer in a seven-run fifth inning yesterday that enabled the Cubs to rout the Los Angeles Dodgers, 9-3, in Chicago.

Trailing, 2-0, entering the fifth, the Cubs sent 11 men to the plate. Leon Durham, Keith Moreland and Jody Davis singled for one run, then Larry Bowa's single loaded the bases. One out later, Hall cleared the bases to finish Burt Hooton (8-5). Pat Zachry relieved and Ryne Sandberg singled Hall home, then Buckner hit his 14th homer.

Steve Trout (8-8) pitched the first seven innings, giving up two runs and eight hits to earn the victory.

There was some question if Hall would be able to play; he'd hurt his left ankle crashing against the center field wall to make a circus catch Sunday. "It bothered me a lot last night, and I iced it all night long," Hall said.

Hall took special pride in his big hit coming off Hooton, who had been quoted as saying: "The only way the Cubs can make the World Series is if they cancel August and September." The newspaper clipping was tacked above Hall's lockers.
