Bill Robinson's grand-slam homer highlighted a nine-run eighth inning last night as the Philadelphia Phillies rallied for a 15-11 victory over the Expos in a game delayed 2 hours 20 minutes by rain in Montreal.

Trailing, 8-4, the Phillies sent 12 men to the plate in the eighth. Pete Rose ended the inning with a fly out, but set a major league record when he passed home run king Hank Aaron with his 12,365th at bat leading off the game.

Loser Jeff Reardon (4-2) gave up six of the Phillies' 19 hits in the eighth.

Robinson and Ivan DeJesus started the inning with singles. Robinson scored on Bob Dernier's sacrifice fly before Rose and Manny Trillo walked to load the bases.

Gary Matthews and Mike Schmidt singled in runs, pulling the Phillies to 8-7, and Trillo scored on a wild pitch by Ray Burris to tie the score. The Phillies went ahead on that play as Matthews scored when catcher Gary Carter tried to throw out Schmidt advancing to second and but threw into center field.

Bo Diaz and Jerry Reed walked to reload the bases and Robinson hit his grand slam, his sixth homer this year, giving the Phillies a 13-8 lead.
