Barnhizer will start in Monday's preseason game against the Mavericks, Brandon Rahbar of DailyThunder.com reports.
With the Thunder resting several players in the second half of the team's back-to-back set, Barnhizer will get the starting nod against Dallas. The two-way player recorded six points (1-2 FG, 4-5 FT), four steals, three rebounds, one assist and one block across 25 minutes in Sunday's win over the Hornets.
