MATTHEW GAWTHROP and Harry Medhurst both made 98 on opposing sides, but it was Mick Shaw's brilliant catch which delivered Eastlake a vital John Gallop Cup victory.
Shaw took an absolute screamer on the boundary to get rid of the dangerous Medhurst as Weston Creek fell 26 runs short of chasing down Eastlake at Kingston Oval on Saturday.
Medhurst single-handedly kept Weston Creek in the game with a brutal display of hitting until he was the last man out trying to bring up his century with a six.
He couldn't clear the rope, allowing Shaw to run back at deep mid-on and secure second-placed Eastlake its sixth win in the competition from eight games.
Eastlake's win was set up by a classy innings from Gawthrop, who dedicated his priceless knock to long-serving club official Ron Oakes, who died on Monday.
A minute's silence was held before the start of play in a fitting tribute to the popular figure.
Gawthrop also fell to a catch in the deep in his quest to reach three figures.
Luke Behrendorff - younger brother of Perth Scorchers star Jason - starred for Weston Creek with the ball taking 4-47, while Michael Spaseski (4-50) was the chief destroyer for Eastlake.
Weston Creek captain Adam Rhynehart lamented his side's wayward bowling on the batter-friendly wicket where it conceded a whopping 30 wides.
He's hoping for a more disciplined performance in Sunday's Twenty20 semi-final with Tuggeranong at Kingston Oval, with the winner to face either Wests/UC or Albury this afternoon.
''If anything, we'll have a little bit of an advantage having played there today to know what to expect tomorrow,'' Rhynehart said.
''It's a good warm-up to play out there.''
Wests/UC paceman Ben Oakley is in great nick after the ACT Comets veteran ripped through North Canberra Gungahlin as his side cruised to a seven-wicket victory at Jamison Oval.
Oakley claimed 4-17 before Matt Condon's half-century easily steered the ladder leaders past North Canberra Gungahlin's total of 9-126.
Elsewhere, Tuggeranong celebrated a six-wicket win against Queanbeyan, while Sam Gaskin's unbeaten 89 guided Ginninderra to a five-wicket victory over ANU.
The Twenty20 competition semi-finals and final will be played on Sunday at Chisholm and Kingston from 9.30am.
