Langholm made the short journey over the border to Longtown on Saturday and suffered another defeat by 38 runs in the Eden Valley league.
Longtown batted first and made a total of 157 for 4 wickets in the 40 overs. Former Langholm player Tony Steele finished on 84 not out for the hosts and Hetherington was still at the wicket on 35.
In the Langholm bowling, Steven Johnstone had 1 for 23 in 10 overs, with Graham Park 1 for 28, Jack Pool 1 for 41 and Duncan Elliott 1 for 45.
Poor batting again let Langholm down with only the odd player showing support to Gregor Park, who reached 59 before being caught by Duggan off the bowling of Steele.
Jason Hall (11) and Johnstone (11) were the only others to reach double figures, with the latter still at the wicket when Langholm were all out for 119 in 36.1 overs.
In the home bowling, Dickinson had 4 for 13 and Steele 5 for 31.
The defeat sends the Milntown outfit hurtling down to eighth place in the 10-team Eden Valley First Division.
