the grade of Lansdowne Street. Huntington Avenue Grounds in Boston. Left and center fields had an incline at the base of the fence. Minute Maid Park in Houston.

The deepest portion of the outfield had an upslope when the park was first built, notably in left center. It was pretty well covered over and leveled out when the bleachers were rebuilt in the 1930s.
