Top seeds: (1) O'Fallon (15-12), (2) Belleville East (18-9), (3) East St. Louis (17-7), (4) Collinsville (12-16), (5) Belleville West (6-19)
Pick: East St. Louis. The Flyers have won five in a row and are 7-2 against the regional field, which includes two wins over Belleville East.
Could challenge: O'Fallon, Belleville East. O'Fallon is 6-2 vs. the field and, like Belleville East, has defeated each team once. Belleville East is 5-4 against the field, with one of those losses coming at Belleville West.
Comment: It sounds elementary, but the champion of this regional will be the team that clicks at the right time. There's far too much parity to handicap with any degree of certainty.
