Joey Levin was the only player to break par to lead Middleton to the championship at the rain-delayed WIAA Division One boys golf regional at Pleasant View Golf Club Wednesday.
The regional was scheduled to be played Tuesday, but heavy rains postponed the tournament to Wednesday.
Levin shot 34 on the Woods and 37 on the Lakes course for a total of one under par 71 for the low score of the day.
Middleton's team total of 295 won the regional.
The Cardinals' Nils Arneson and Emmet Herb both shot 74 and Brady Thomas added a 76 for the Middleton team total.
Waunakee (324), Madison Memorial (326) and Oregon (329) advanced their teams to the sectional next Tuesday at Reedsburg Country Club.
Also qualifying as individuals for the sectional are Verona's Austin Lois (81), Sauk Prairie's Jordan Powell (82) and Stoughton's Sam Anderson (84).
