The agency saw off competition from Cliff Freeman and Partners, Young & Rubicam and the incumbent, Laird+Partners, to pick up the Dr Pepper-owned brand.
The account win comes six months after the Interpublic Group agency was awarded the lead agency status on the Dr Pepper Snapple Group account.
Snapple spent $25 million last year in measured media, and has already spent $15 million up to July of this year.
