The 2010 eighth-round pick out of LSU had a pair of doubles in his previous two games before Thursday's barrage.
After popping out to shortstop in his first at-bat, Dean brought Jake Lemmerman and Nick Akins home on his first double of the night -- a line drive to right field off of Brewers starter Tyler Cravy in the third inning. Dean scored his only run of the game when Jesse Bosnik followed with a double of his own to make the game, 7-1.
Dean doubled to center in the fourth off of reliever Tony Butler to bring Robert Croyle, Akins and Jonathan Garcia across the plate.
After Helena called on Thomas Keeling to pitch the sixth, Dean hit a bases-empty double to center. He also drew a walk in the seventh.
Dean's 10th double of the season -- a shot to right in the eighth -- scored Lemmerman and Austin King to give the Raptors a 17-run lead.
Before Thursday, Dean's only multiple-RBI game was two in a June 30 loss to Orem. He had never had four hits in the same game, but doubled and singled twice in a loss to Casper on June 23, singled three times in a loss to Idaho Falls on July 4, and doubled twice and singled while falling to Missoula on Tuesday.
Dean is hitting .298 with a homer and 14 RBIs through 24 games.
Greg Wilborn earned the win for Ogden by fanning nine and allowing one run on six hits over six innings. Akins homered and singled and Lemmerman added a longball and a double for the Raptors (19-12).
