A full colts programme was possible last week, but Biggar-Peebles had to concede to St Boswells as they were unable to raise a team.
Elsewhere, there were victories for Kelso-Manderston and Gala.
Batting first, the former amassed a league record 163 for 3 thanks to half-centuries from Mark Henderson and Tom Galbraith, while Angus Roberts who was left stranded on 49. A young Hawick-Selkirk team were restricted to 72 for 9.
Gala defeated Borders Women by 10 wickets as Jack Halls and Craig Hancock batted past the ladies’ total of 61.
The Braw Lads also made it into the last eight of the Scottish Under-15 Cup, defeating SMRH by nine wickets on Friday evening.
Some tight bowling restricted the home side to 71 for 7 with Robbie Pringle (2-12) and Jack Halls (2-4) the pick of the bowlers.
Craig Hancock was the only victim as Josh Irvine (42) and Halls (13) raced past their Edinburgh hosts’ total in less than 10 overs.
The pick of the games from week six of the under-13 league was the low-scoring match between Manderston and Hawick.
Manderston were shot out for 45 by their visitors as Ronan Alexander returned figures of 4 for 8.
However, Alexander’s Borders Under-13s team-mate Duncan Sim gave his side an unlikely victory, taking five wickets for just four runs as Hawick fell to 40 all out.
In the other game, Biggar-Peebles Under-13s ran up their highest total of 137 for 1, thanks to some wayward St Boswells bowling and good batting from Jack Savage and Henry Adams. In reply, St Boswells resisted stoutly in losing eight wickets, but fell well short of the target, reaching 52.
Melrose Under-11s began the defence of their KO Cup title by beating Gala Under-11s comfortably in the first round of the Rowan Boland Memorial Trophy.
Both Borders Under-13s and under-17s suffered narrow defeats to North Northumberland and Pentlands respectively.
The Under-13s friendly on a scorching hot day at Etal saw their hosts score 131 for 7. The young Borderers, in reply, looked to be coasting to a well-earned victory at 107 for 4 with 13 overs to spare. But the next six overs brought the remaining six wickets for only 16 runs and victory to the home team.
At Selkirk, the Under-17s struggled initially to contain the Pentlands openers in their Inter-Area Championship match, but the Borderers fought back to restrict their visitors to 227 all out.
Theit reply was steady and unspectacular, but littered with unlucky dismissals against early pace. The homesters eventually fell behind the run-rate and were all out for 187.
z Hawick’s primary school tournament will culminate on Saturday, June 18, when Drumlanrig Spitfires play Henholm Heroes for the Margaret Johnston Memorial Trophy.
The day begins at 9am.
