WHEATON – The Geneva boys basketball team posted winning records in three of coach Phil Ralston’s first four years with the program but a shortage of postseason success – a bugaboo for the program long preceding Ralston’s arrival – has remained a sore spot.

In year five of Ralston’s tenure, the Vikings appear to be finding their postseason sea legs.

A hard-nosed, inspired effort from start to finish Thursday earned 12th seeded Geneva a 55-49 upset victory against No. 5 seed Hinsdale Central in an IHSA Class 4A Wheaton Warrenville South Regional semifinal. The win vaults the Vikings into tonight’s regional championship against DuPage Valley Conference powerhouse West Aurora.
