A week after losing their unbeaten tag, SHEFFIELD returned to winning ways at Riverside.
Marc Simonds proved the difference, smashing an unbeaten 96 to steer the run chase home.
Earlier, the home side's young guns had helped them post a defendable 231 total.
In the week that The Examiner's sports reporter and Blues top-order batsman Josh Partridge interviewed teenage teammate Cooper Anthes about his highest first-grade score of 64, the pair teamed up to write a few more headlines with a 102-run partnership.
Anthes again clocked up 64, albeit off 13 fewer deliveries, as Partridge recorded his maiden half-century (52) and Matt Kerrison added 51.
Sam Robinson (3-46) topped the Mountaineers' bowling figures and Lyndon Stubbs (3-35) repeated the feat for the Blues but they had no answer for Simonds who claimed six maximums in his devastating display.
BURNIE made hard work of chasing down Westbury in a low-scoring affair between second and third.
A week after conquering the Mountaineers, the Shamrocks could only muster a top score of 21 courtesy of Corey Briggs' return from Hobart Hurricanes indigenous duty. However, five other batters made double figures as the visitors were all out for 129.
At 3-100, the hosts appeared to be cruising but when that became 6-100, including top scorer Brady Yates (35), it was a different ball game.
Kieren Hume (4-17) was on fire but Kurt Lamprey's unbeaten 23 saw Burnie home with one wicket and three overs to spare.
Two hefty stands were the story of SOUTH LAUNCESTON's three-wicket loss to Ulverstone.
A partnership of 128 between Sean Harris (80) and Ishang Shah (70) helped the Knights reach 7-231.
But Jacob Snare (76) and Alex Wynwood (50) put on 121 for the second wicket to lay the foundations for a sound chase which was completed with two overs left.
WYNYARD chased down Mowbray with five wickets and seven overs to spare.
Eagles opener Sam Canny (32) hit his highest score of the season but nobody else could get out of the 20s as the visitors recorded 7-160.
Wynyard were in trouble at 3-10 before Hashan Abeyrathna added 31 runs to his three wickets and an unbeaten stand between Gregg Sharman (54) and Brodie Stokes (51) saw the hosts home.
LATROBE made short work of chasing down Launceston's 119 all out, in which captain Alistair Taylor top scored with 31.
Callan Morse (41) led the chase to a six-wicket win as Tom Gray took 2-17 for the Lions.
