Chasing a target of 333 on Sunday, the Warriors were cruising at 1-121 but the Vics were able to apply the brakes after danger man D'Arcy Short departed for 44 off 45 balls.

WA stormed into the semi-final on top of the table and unbeaten in five matches but Josh Inglis was the only batsman able to post a half-century when he scored 63.

The Warriors were eventually bowled out for 269 after 45.5 overs in front of 1381 fans.

"We were confident and we have been all tournament, we just hadn't actually put it all together yet," Victorian skipper Peter Handscomb said.

"So it's great to come into a semi-final and actually put it together.

"We could have been in a better position (early) but it was great to consolidate from there and come away with a pretty good win."

Glenn Maxwell failed to impress with the bat or ball but he affected the pivotal run-out of WA skipper Ashton Turner for seven and caught Inglis off the bowling of Chris Tremain shortly after in a crucial period that turned the contest in his side's favour.

He also ended the game with an outrageous one-handed outfield catch to remove Usman Qadir.

After making 58 from 63 balls, Nic Maddinson cleaned up the the Warriors' tail with 4-28 from 4.5 overs.

Victoria lost early wickets after winning the toss but rallied to be all out for 332 off 49.5 overs.

Handscomb continued his outstanding run of form with his fourth half-century in a row, the Victorian skipper top scoring with a well made 80 from 73 deliveries.

Nathan Coulter-Nile was the pick of the WA bowlers, finishing his 10 overs with figures of 3-50. Andrew Tye also chipped in with 2-64.

Victoria were in trouble early at 2-10, with Cameron White and Travis Dean both out cheaply.

But Handscomb combined with Marcus Harris for a pivotal 102-run partnership.

Player-of-the-match Harris provided the dash, stroking the ball to all parts of the ground with 13 fours and two sixes in his 73 from 49 balls before he was bowled by Qadir.

Maxwell strode to the crease at No.5 but failed to build his case for a Test recall, out for seven when Josh Philippe took a good catch in the deep off the bowling of Coulter-Nile.

From 9-292 in the 47th over, Fawad Ahmed with 16 and Andrew Fekete on 12 not out combined for what would prove to be a vital 40-run last-wicket partnership.
