Despite Colin Thornton producing his third half-century in successive weeks, Bomarsund found themselves on the receiving end of a six-wicket defeat to Blyth at the Welfare.
The captain and Stephen Thain produced a 73-run stand as the hosts managed to make 232 all out inside 49 overs with the help of Liam Besford at the end of the innings.
In reply, opener Dave Dent blitzed his way to 78 and Andy Kemp (59) helped the visitors reach their target inside 33 overs with six wickets still in hand.
After losing the toss, Bomarsund made a steady start to their innings with Colin Thornton and Adam Purvis putting on 41 before the latter departed.
Thain joined the skipper at the crease and the pair played some clever strokes during their impressive partnership for the second wicket.
Colin Thornton, who hit seven fours during his innings, was trapped in front for 53 with the score on 114, but the side were in trouble with four consecutive wickets for under 50 runs.
However, Sam Thornton and Besford steadied the collapse and put on 48 with the latter ending not out on 32, which included four fours and a six.
Another two wickets fell after Sam Thornton departed, which left the hosts all out for 232 inside their allotted overs, thus being all out for their sixth time in seven games.
Blyth made a fast approach to the run-chase as opener Dave Dent made a quick-fire 78, which included 17 boundaries, leaving the visitors in a comfortable position.
Regardless of losing a couple of wickets, the batsmen continued to make an impact on the innings as Andy Kemp produced a knock of 59 from 30 balls.
Andy Clark (38) and Mark Lawrence (24) made sure that the target was chased down with ease as the visitors reached the target in blistering time.
Chris Mollon and Scott McBride finished with figures of 2-60 and 2-68 respectively, but the bowlers suffered after Blyth’s batsmen took the game to them.
The defeat leaves the firsts sitting second bottom of the division, with an important trip to Ashington Rugby club next Saturday.
