The Class 7A semifinal round baseball playoff series between Parkview and North Gwinnett had to be postponed on Tuesday because of a watering problem at the field. The series has been pushed back one day. Parkview will play a doubleheader at North Gwinnett on Wednesday, the 15th, beginning at 4:30 p.m. The third game of the series, if necessary, would be Thursday, the 16th, beginning at 6:00 p.m., also at North.
