Victoria eased to their 167-run victory target before lunch on day four as South Australia ended a forgettable season with a sixth defeat.
The Vics effectively played the match with only four recognised batsmen after electing to field five bowlers with an eye on next week's final, only to lose in-form run-scorer Nic Maddinson to injury on day one.
The final-day win was set up by a 130-run opening stand between Travis Dean (61) and Marcus Harris (65) after they resumed day four at 0/69.
The Redbacks sparked a triple breakthrough after Harris was stumped off the bowling of Tom Andrews, quickly losing Will Pucovski (0) and Dean to be 3/135.
But Seb Gotch (15*) and Matt Short (15*) were able to knock off the remaining 32 runs.
Andrews finished the second innings with figures of 2/42 to cap an impressive return to first-class action in the last two games of the season.
Sturt captain and middle-order batsman Brad Davis also made an impression, marking a maiden half-century in his second game in SA's second innings 192.
Travis Head (67) and Andrews (59) were the only other major contributors with the bat, helping SA to 260 in the first innings.
A late surge by the returning Chadd Sayers (3-50) in the closing overs of the second day's play had kept Victoria's first innings within striking distance.
