         4 . The oven appliance of  claim 3 , wherein said runner tube is spaced apart from said first orifice and said second orifice by less than about six inches along the lateral direction. 
     
     
         5 . The oven appliance of  claim 3 , wherein said first and second scoops each have an upstream surface, the upstream surface of said first scoop facing said first orifice and configured for obstructing at least a portion of a flow of fuel through the passage of said first burner tube in order to direct fuel into said runner tube, the upstream surface of said second scoop facing said second orifice and configured for obstructing at least a portion of a flow of fuel through the passage of said second burner tube in order to direct fuel into said runner tube. 
     
     
         6 . The oven appliance of  claim 1 , further comprising an ignition device positioned adjacent said first burner tube, said second burner tube, or said runner tube. 
     
     
         7 . The oven appliance of  claim 1 , wherein the cooking chamber of said cabinet extends between a front portion and a back portion along the lateral direction, said runner tube positioned adjacent the back portion of the cooking chamber. 
     
     
         8 . The oven appliance of  claim 1 , further comprising a flame spreader positioned above at least one of said first burner tube and said second burner tube along the vertical direction. 
     
     
         9 . The oven appliance of  claim 1 , wherein said first and second burner tubes each include a respective Venturi throat, said runner tube positioned adjacent and downstream of the Venturi throats of said first and second burner tubes. 
     
     
         10 . The oven appliance of  claim 1 , wherein said runner tube has an upstream portion and a downstream portion, said first and second scoops mounted to said runner tube at the downstream portion of said runner tube. 
     
     
         11 . A gas burner assembly for an oven appliance, the gas burner assembly defining a vertical direction, a lateral direction, and a transverse direction, the vertical, lateral, and transverse directions being mutually perpendicular, the gas burner assembly comprising:
 a pair of burner tubes spaced apart from each other along the transverse direction, each burner tube of said pair of burner tubes defining a passage for directing a flow of gaseous fuel therethrough;   a runner tube extending between said pair of burner tubes along the transverse direction and fluidly connecting the passages of said pair of burner tubes; and   a pair of projections mounted on opposite transverse ends of said runner tube, each projection of said pair of projections positioned within a respective passage of the passages of said pair of burner tubes.   
     
     
         12 . The gas burner assembly of  claim 11 , wherein the projections of said pair of projections are integrally mounted to said runner tube. 
     
     
         13 . The gas burner assembly of  claim 11 , further comprising a pair of orifices, each burner tube of said pair of burner tubes defining an inlet, each orifice of said pair of orifices positioned at a respective inlet of said pair of burner tubes and configured for directing fuel into a respective passage of said pair of burner tubes. 
     
     
         14 . The gas burner assembly of  claim 13 , wherein said runner tube is spaced apart from said pair of orifices by less than about six inches along the lateral direction. 
     
     
         15 . The gas burner assembly of  claim 13 , wherein each projection of said pair of projections has an upstream surface, each upstream surface of said pair of projections facing a respective orifice of said pair of orifices and configured for obstructing a flow of fuel through the respective passage of said pair of burner tubes. 
     
     
         16 . The gas burner assembly of  claim 11 , further comprising an ignition device positioned adjacent one of said pair of burner tubes.
