COLUMBUS — Behind two sterling outings by pitcher Bria Bush, the Buford softball team’s pursuit of a sixth consecutive state championship got off to a good start in Class AAA on Thursday in Columbus. After cruising to a 7-1 victory over Jackson in the first round of the state tournament final, Bush struck out 12 batters en route to a 4-0, one-hit shutout over Chapel Hill. With its second win, Buford sets up a matchup with Central-Carrollton in the third round, which will be played at 5 tonight.
