Lightning Bolts made it three wins out of three in the Emerging Interpros with a comprehensive win over Munster Heat, while the Knights beat the Warriors by 53 runs at Ardmore.
Murtaza Sidiqui's 49 was the highlight of Heat's modest 138, which came at even time and contained 5 fours and 3 sixes.
Teenagers Cillian McDonnell (3-11), Gavin Hoey (3-27), and Mikey O'Reilly (2-14) claimed the bowling honours for the Dubliners.
Mitchell Thompson's unbeaten 59 (6 fours, 3 sixes) coupled with Jamie Grassi's 49 ensured an easy win as they passed the total in just 22 overs.
In the North West, the Emerging Knights win was set up by a solid batting display with five of the top six making contributions as they posted 249 for 9.
Cade Carmichael top scored with 55, with Morgan Topping (45), CJ van der Walt (41*), Ollie Metcalfe (39) and John Matchett (21) in the runs.
Graham Kennedy (2-22), Ryan MacBeth (2-38) and Gregory McFaul (3-48) were best with the ball for the hosts.
The Warriors never really looked like chasing it down as they lost early wickets, and were always behind the required rate.
Ryan Hunter impressed with his 33, but it took late runs from Varun Chopra who hit an unbeaten 51, dominating a last wicket stand of 40 with Ryan Macbeth to give the scoreboard a closer look than it was in reality.
For the visitors, there was three wickets for both Matthew Humphreys and Tom Mayes, while Cian Robertson picked up two.
