SYLVESTER TON SEES SULLY TO VICTORY; Swalec Premier.
Usk were invited to bat, and posted a combative score of 275-4, with Neil Perrett cracking a superb 109.
He figured in an opening stand of 151 with Lorne Burns (62) only for Jamie Sylvester (3-43) to not only take vital wickets, but slow things down.
The inaugural league champions were then given a flying start by the experienced duo of Ryan Sylvester and Michael O'Shea, who fashioned a 128-run stand.
Though O'Shea fell for 65, Sylvester carried his bat in hitting 107 (one six, 15 fours).
Captain Lloyd Smith also contributed an unbeaten 80 (three sixes, nine boundaries).
This enabled Sully to reach 277-1 off just 36 overs, and it consolidated their position at the top.
Reigning champions Cardiff had things very much their own way at struggling Ynysygerwn, triumphing by five wickets.
Ynys were removed for 156 off 39 overs with only Richard Grant (44) and Geraint Bowden (31) troubling the scorers.
Matt Smart (4-36) picked up three wickets in one over to sway the issue while spinner Andrew Thomas captured 3-26.
Harry Bowles (68) was then the central performer, as Cardiff cruised home on 157-5 in the 39th over.
Newport tossed away a position of strength during a drawn game at Ammanford, scoring 247-9 in reply to 259-6. But the Spytty Park side were 235-6 with three overs to go, but ultimately they were left had to reflect on three run outs.
Imran Hassan hit a magnificent 113 and aided by Gary Wood (71) they figured in a second-wicket partnership worth 138.
Earlier, Ammanford had batting heroes in Matt Fisher (75), Rhys Davies (57) and captain Alun Evans (50) with Harry Powell (3-62) the chief wicket-taker.
Port Talbot Town, who won the toss and posted 236-6, had the better of a drawn game with Bridgend Town at Newbridge Fields.
Sean Griffiths (62) and Anthony Thomas (57) were the main run-getters and during the last 10 overs they amassed 88 runs, including 19 off the last.
Bradley Wadlan (4-60) kept Bridgend in the game, but their batting then came up well short of the required mark.
After Dave Goodway (28), Wadlan (27) and Grant Humphries (22) departed, Bridgend put up the shutters and closed on 162-6. Lewis Jones (3-23) did threaten for the Pirates while Stuart Phelps (1-31) and Ian Thomas (1-35) kept the runs down.
Honours also finished even at The Marespool, as Pontarddulais got 222-6 in reply to a Mumbles score of 238.
Former Glamorgan all-rounder Darren Thomas became the fourth centurion of the day, contributing a hardhitting 126 (one six, 12 fours).
Chris Nelson (17) helped him add 63 for the seventh wicket with Robert Croft returning 3-36 and Gary Arrowsmith 3-37.
Former England star Croft also had a decent day with the bat, hitting 57, while Matt Carey and Arrowsmith both chipped in with 43s during a strong Bont response.
