Bowman's team, Hendrick Motorsports, had pledge to donate at least $200,000 to relief efforts in the war-stricken country, plus an extra $2,000 for every lap one of its cars led.

Bowman held off teammate Kyle Larson in a two-lap overtime shootout for the victory after they'd led 16 and 27 laps each, while William Byron led 8 in the #24 Hendrick car on his way to a fifth place finish.

The 51 laps led added an extra $102,000 to the donation to Smaritan's Purse, bringing it to $302,000.
