Stamford moved top as the merry-go-round continued in the South Lincolnshire and Border League Premier Division on Saturday.
Town’s 278 for six proved too much for Welby with Liam Davé struck a superb unbeaten 155.
In reply, Welby managed 156 before being dismissed in the 35th over. Brett Bennett returned the best figures with four wickets for 28 runs from a little over seven overs.
As a result, Town are three points clear at the top although they have played one game more than their closest rivals, Billingborough and Boston.
The second and third-placed sides were locked in a thrilling battle at Boston where the hosts won by four runs.
Boston batted first, falling to a modest 144 all out in the 41st over with Luke Hollingworth taking six of the wickets. This gifted Billingborough four extra overs and 40 from Dave Newman and Chris King’s 42 saw the home side to 123 for five. But once King was out, Boro sliped to 133 for eight and despite the efforts of the lower order, the final wicket fell for 140 in the 47th over.
Trevor Walton’s 113no for Skegness 2nd XI, delivered a five wicket win for the seasiders against Bourne 2nd XI at the Abbey Lawn.
Bourne batted first Tom Bentley one shy of a half century and David Christmas scoring 52 as the hosts made 233 for 9 with Mark Chamberlain claiming five Bourne wickets for 64 runs.
Skegness opener Walton refused to budge all innings and the visitors reached their target in the 42nd over with five wickets in hand. Chris Binns was the pick of the Bourne bowlers with two for 37 from seven overs.
Elsewhere, West Indian signing Cleton Payne helped Grantham to victory over Moulton Harrox with an innings of 122.
Long Sutton retained the lead in Division One but were made to fight all the way in a low scoring game against Friskney.
Second-placed Baston kept up their challenge for honours with a four wicket win over Blankney.
Blankney managed just 119 as Baston kept the bowling tight with Mark Richardson’s four for 22 off 4.2 overs the most impressive figures. Liam Davies bagged three for just 25 with Andrew Keen and John Lamin also among the wickets. Adam Hilless missed out on the wickets but didn’t give away many runs, conceding just 15 in his six overs.
Baston’s reply got off to an excellent start with Richardson (45), Davies (40) setting a solid foundation. Lamin added 38, and Ben Hudson an unbeaten 34 as Baston eased to 123 for 6 in 39 overs.
Billingborough 2nd XI beat Boston 2nd XI by 41 runs after posting 175 for 4.
Matt Cox made 59 and Josh Scott and unbeaten 69 for Boro whose tally never looked in any danger after early Boston wickets fell cheaply.
Peter Simmons with three for 25, and Matt Cox with three for 35 returned the best figures.
