Warriors batsman Tom Beaton celebrated Christmas with an early present as he struck his maiden first grade century for Mount Lawley in the weekend's WADCCI action.
Beaton's 111 steered the Hawks to victory over South Perth at Richardson Park. He was well supported by team mate Shane Rakich, who struck 125 and shared in a 155-run fourth wicket stand with the Warrior.
Elsewhere, Nathan Coulter-Nile brought his big-hitting form from the Gabba to Lark Hill as Subiaco-Floreat defeated Rockingham-Mandurah.
Coulter-Nile, who smashed an unbeaten 21 from six deliveries to guide the Scorchers to victory against the Brisbane Heat during the week, belted 64 from 47 balls as the Lions maintained their place in the higher reaches of the table.
Scorchers team mate Ashton Agar was another to notch up a maiden first grade ton, scoring 108 for University in the second innings of their match against Claremont-Nedlands. The Tigers had earlier claimed the first innings honours.
Tim Armstrong pressed his case for a KFC T20 Big Bash League call-up, taking 5-50 in 14.5 overs for Fremantle as the port boys had the better of Midland-Guildford at Stevens Reserve.
Warriors rookie Cameron Bancroft struck an unbeaten 96 in the second innings of Willetton's match against Melville at Burrendah, but the Storm had earlier claimed victory on the first innings. WACA Development Squad member Simon Mackin claimed four wickets for the Dragons.
Scarborough moved into finals contention after posting an outright win against Gosnells at Sutherlands Park, Bayswater-Morley was too strong for Perth at Fletcher Park, while Joondalup claimed bragging rights in the northern derby against Wanneroo at Iluka.
