The Warriors have been defeated by the West End Redbacks in a four-day practice match held during their pre-season camp in Brisbane.
Chasing a target of 285 to win on the final day, the Warriors were dismissed for 249 to hand victory to the Redbacks by 35 runs.
The Redbacks batted first and were dismissed early on day two for 369. Ex-ACT batsman Sam Miller top-scored with 116, Alex Ross made 79, while ex-skipper Michael Klinger chipped in with 63.
Nathan Rimmington took five wickets to be the pick of the Warriors' bowlers, Michael Hogan and Jasom Behrendorff claimed two each, and Ryan Duffield picked up one.
The Warriors replied with 239. Opener Liam Davis led the way with 79, while several batsmen got starts but were unable to convert into the big score required.
The bowlers hit back for the Warriors in the second innings, bundling the Redbacks for 154. Test spinner Michael Beer snared 4-19 from 16 overs, young quick Matt Dixon picked up 3-36, while Duffield (two) and Rimmington (one) were the other wicket-takers.
The Warriors started their run chase in bright fashion through openers Sam Whiteman and Marcus Harris, with their first wicket stand yielding 90 runs.
Three wickets fell in quick succession as Whiteman (60), Harris (36) and Shaun Marsh (three) departed to reduce the Warriors to 3-101.
The loss of Davis (nine) and Nathan Coulter-Nile (no score) saw the Warriors fall deeper into trouble at 5-118, but Mitchell Marsh and Tom Triffitt came to the rescue with a 72-run sixth wicket partnership.
The loss of Marsh for a brilliant 78 and Triffitt for 28 almost ended the resistance and the Warriors fell just short as they had done in one-day fixtures against Queensland and New South Wales last week.
For the victors, left-arm quick Gary Putland - the hero of the Redbacks' RYOBI One-Day Cup final triumph earlier this year - was the hero as he took 6-58.
The Warriors return to Perth tomorrow to continue preparations for the start of the 2012-13 domestic season, which begins on Sunday week with a RYOBI Cup match against the Blues at the WACA Ground.
