Lowerhouse deposed early league leaders East Lancs with an impressive 129-run win at the Neville Gee (Recruitment) Ground on Sunday.
The House finished runners-up last season after back to back titles, but they made a statement of intent as they picked up their second win from the opening four games.
Joe Hawke was again among the runs, hitting a 49-ball 51 for his second successive half century, while professional Cobus Pienaar followed suit, cracking 56 from 67 balls.
Openers Jack Edgar (37) and Joe Martin (24) had laid the platform for victory with a partnership worth 59, while Matt Walker chipped in with 27 as the West Enders closed on 254-9, the biggest score of the day in the Lancashire League.
And Charlie Cottam’s men showed the depth of their bowling attack, as six players claimed wickets to dismiss the Blackburn side for just 110 in reply, of which veteran David Pearson top-scored with 30 not out.
Burnley, meanwhile, are without a win after four games.
Bharat Tripathi’s sude came away from Bacup opn the end of a five-wicket defeat.
The home side won the toss and inserted Burnley, and they were soon in trouble, having collapsed to 30-5 within the first 10 overs.
Michael Kelly (12) and Steve Brunt set about rebuilding the innings on a typical slow and green seaming early season wicket, which proved a perfect pitch for the home professional Haseeb Azam, who bowled beautifully in taking 7-32 off 15 overs.
He was ably assisted by David Warren (2-34 off 14), and it got worse for the visitors as they slipped to 50-7 as Kelly and Matt Lamb fell.
Brunt held the innings together with a well-composed 35.
With the help of debutant Janghir Liaqat (11), he put on a partnership of 23 and a further partnership of 24 with Graham Lalor, but Burnley were bowled out for 101 off only 33 overs.
With early wickets required to put pressure on the home side, Brunt got one, but despite Lalor bowling well, the home side progressed to 74-1 and were cruising to victory until a collapse occurred, with professional Chris Holt turning a ball onto the stumps off his own bowling to dismiss keeper Matt Collinge for 22, and then Liaqat took 3-17 off his six overs to reduce Bacup to 84-5.
But this was to no avail as Bacup got over the line with no further loss and with 10 overs to go.
Burnley entertain Nelson on Sunday in the first mini-derby of the season, while Lowerhouse make the short trip to Colne.
In the Ribblesdale League, Read’s perfect start came to a shuddering halt in a Ribble Valley derby at home to leaders Whalley.
Evergreen Dave Howard took a remarkable 7-31 from 8.5 overs, including a hat-trick, to help dismiss their hosts for 59, before Whalley knocked off the required runs in 22 overs for the loss of three wickets.
Padiham suffered a six-wicket defeat to Salesbury, after Ed Foster took 5-50 to dismiss Callum Clarke’s men for 130.
