Ballyspallen surged up the table with a crushing nine-wicket victory over Letterkenny.
The home side dominated from the outset after bowling Letterkenny out for just 57 in 24.3 overs. Michael O'Brien was the chief destroyer, producing a devastating spell of 5-8, while Dylan McElhinney (2-5) and Pushpender Singh (2-23) provided excellent support.
Only Ateeq ur Rehman offered any meaningful resistance for Letterkenny, battling to 28 and striking two sixes as wickets tumbled regularly around him.
The chase was completed in emphatic fashion despite an early setback when Hassan Shahid was bowled by Wasiq Riaz for just one.
Pushpender Singh then took centre stage, blasting an unbeaten 38 from only 19 deliveries. His innings featured three sixes and three fours as he quickly removed any doubt about the outcome. John O'Brien provided solid support with 14 not out as Ballyspallen raced to 62-1 in just 5.4 overs, securing maximum points from a one-sided contest.
Glendermott moved top of the Championship standings with a convincing six-wicket victory over Eglinton.
Earlier, Eglinton were bowled out for 150 in 40.4 overs despite contributions from Dunith Jayathunga (33), Andy Millar (30) and Jack Martin (26). Alan Johnson claimed 3-22, while Trevor Britton and Ben Mills took two wickets apiece.
The chase suffered an early setback when Ben Mills fell in the second over, but Blayde Capell and former Eglinton player Craig Averill transformed the contest with a superb second-wicket stand of 135.
Capell struck an unbeaten 78 from 62 balls, including eight fours and three sixes, while Averill made 48 with eight boundaries.
Robbie Millar's 3-32 earned Eglinton two valuable bonus points, but Glendermott comfortably reached their target just before the halfway stage.
Bonds Glen's explosive batting line-up was in devastating form again as they overwhelmed Ardmore by 76 runs in a match reduced to 28 overs.
Despite losing Dharm Singh in the opening over, the Bee Gees recovered through a second-wicket partnership of 138 between Danie Rossouw and Sam Haslett.
Rossouw struck 72 from 55 balls, including six fours and three sixes, while Haslett made 61. The contest was effectively settled by a blistering fourth-wicket stand of 97 in just 34 balls. William McClintock smashed 73 from only 25 deliveries, launching 10 sixes and three fours, while Heinrich Roberts added an unbeaten 24.
Ardmore's reply never seriously threatened the target despite contributions from Vimal Dwivedi (40) and Kasun Aberaytne (37), finishing on 169-6.
Killyclooney continued their impressive season with a comprehensive 97-run victory over Burndennett. After slipping to 39-3 thanks to early strikes from Usman Azhar and Ryan Barr, they recovered through a crucial 92-run fourth-wicket stand between Keenan Viera and Alan Colhoun.
Viera was outstanding, hammering a run-a-ball 124 featuring 20 fours and five sixes. Late acceleration came from Mark Gordon, whose 22-ball 33 included three fours and three sixes, while Jason Wallace smashed 34 from 18 balls and Richard McMorris added 26 from 14 deliveries as Killyclooney reached 283.
Burndennett's reply was respectable, with Corey Roulston making 38, but they were never seriously in contention. Viera completed an excellent all-round display with 3-33 as Killyclooney maintained their strong start despite winter departures.
