What won the race: Scoring his fourth-straight Mississippi State Championship Challenge Series victory and fifth-straight overall win, polesitter Bub McCool of Vicksburg, Miss., nipped third-starting Chad Thrash of Meridian, Miss., by .632 seconds for $2,000 at Hattiesburg Motorsports Park.

Key notes: McCool also won MSCCS events May 2 at Columbus Speedway, May 8 at Greenville Speedway and May 9 at Magnolia Motor Speedway. ...
