Ryan Roberts hit a grand slam, Chris Young had the first two-homer game in Arizona's postseason history and Diamondbacks beat the Milwaukee Brewers 10-6 Wednesday night to force Game 5 in the NL division series.
A day after rolling over the Brewers 8-1, the Diamondbacks struck quickly and often in Game 4, scoring five runs in the first inning off Randy Wolf.
The Diamondbacks became the second team -- with the 1977 Dodgers -- to hit grand slams in consecutive playoff games.
Arizona evened the series at 2-all and sent it back to Milwaukee for the decisive game Friday. It will be a rematch of Game 1 between 21-game winner Ian Kennedy of the Diamondbacks and fellow right-hander Yovani Gallardo.
