Kelso won the toss at Boghall on Saturday and elected to bat against West Lothian.
Captain Dougie Wilson and opening partner Mark Henderson got the Tweedsiders off to a great start with a stand of 50 before Henderson fell for 17.
Wickets started to collapse on a regular basis with Jason Gibson being the second top scorer with 19. But Wilson stood strong and made 84 as Kelso finished on 193 for 9 after their 50 overs.
Following the interval, the visitors came out strong, taking three wickets in 15 overs. With the home batsman riding their luck at times, however, wickets became fewer and West Lothian found themselves back in the game with a stunning 62 from the hard-hitting K. Smith.
The game changed when Murray Scott came on to bowl, his good line and length saw Kelso take their catches and the game swung back their way. Wickets tumbled and Kelso won by 38 runs with Scott and Stevie Patterson being the pick of the bowlers with seven wickets between them.
