Braun to 4 teams; Scott to drive

Quote :

Brian Scott joining Braun; team expanding to 4 cars: Braun Racing announced that it will be expanding its already successful organization to field four NASCAR Nationwide Series entries in 2010. Brian Scott, who has driven a select number of races for the team this season, has been named as driver of the team's fourth Toyota Camry. Sponsor, car number as well as crew chief and personnel for Braun Racing's fourth entry will be announced in the coming weeks.(Braun Racing PR)(11-9-2009)

So, they've got:

Jason Leftler in the 38 (and 10 for a few races)
Reed Sorenson in the 32 (and 10 for a few races)
Kasey Kahne rounds out the season in the 38.
Brian Vickers rounds out the season in the 32.
Brian Scott full time in the 4th car.
Who drives the 10 in the other races? Or, could it just be part time?
