Will Mellors-Blair's goal in the 39th minute held up as Detroit City FC defeated intrastate rival Lansing United, 1-0, before 3,701 Sunday at Cass Tech.
The victory landed Detroit (5-2-1) in a first-place tie with Lansing (5-2-1) in the Midwest Region of the National Professional Soccer League. The win also avenges a 3-1 loss to United in East Lansing May 31.
Goalkeeper Alexandre Bouillennec (Saginaw Valley) made three saves, including one off a goal-bound header by United's Matt Brown in the 45th minute.
The tense occasion was reflected in six yellow cards being issued, four to Lansing and two to Detroit.
Detroit hosts Michigan Stars at 7:30 p.m. July 11 at Cass Tech.
