Edwards whacks career-high ton to lift Blues against SA

South Australia were 1-55 in reply and trailed the visitors by 392.

At the crease are Kelvin Smith (37no), in his first Shield match for four years, and Daniel Drew (10no).

Earlier, NSW's batters were rarely troubled as they advanced from their overnight 6-299.

Fast bowler Ben Dwarshuis hit a career-best 60 not out as he and Edwards added 127 for the eighth wicket.

Despite the home side's woes with the ball there was also a career-best for Nathan McAndrew, who claimed 6-97 on a challenging wicket for bowlers.

NSW are seeking to avoid completing their season without a win for the first time in a 10-match season.
