South Australia 4 for 368 dec (Ferguson 100*, Floros 4-85) and 2 for 228 (Cosgrove 78) beat Queensland 8 for 443 dec (Stevens 158, Hartley 142*) and 152 (Burns 98, Sayers 6-34, Zampa 4-45) by eight wickets
Chadd Sayers and Adam Zampa demolished Queensland before Mark Cosgrove, Tom Cooper and Callum Ferguson rattled South Australia to an eight-wicket victory in the Sheffield Shield match at Adelaide Oval.
The Bulls started the day at 2 for 128, well placed to set Redbacks a challenging target, but Sayers followed up his first innings hat-trick with the best figures of his career to pluck out the visitors last eight wickets for 22 runs.
Most eye-catching among these was a quicksilver leg-side stumping by Tim Ludeman to remove Jason Floros, reminiscent of the best work of Redbacks' coach Darren Berry.
Zampa's burgeoning legspin was also significant to the abrupt turn in the direction of the match, as he ran through the Queensland tail before ending the innings with the wicket of Joe Burns, who was stunned by the collapse around him and ultimately out for 98.
Andrew McDonald fell early in the Redbacks' chase when glancing James Hopes behind, but Cosgrove, Cooper and Ferguson all played with authority to deliver their first outright win at Adelaide Oval since the ground's drop-in wickets were installed in 2013.
