The first clear chance of the match came in the 10th min when Aidan Ward, making his first start for Carluke sent an excellent ball in to the path of Ian Watt who in turn squared a pass to Ryan Smillie but after out stripping his marker his shot was just wide of the target.
This effort was followed closely by Lesmahagows first effort when home defender Scott Burns was caught out allowing the Gow in on the right but the final shot went harmlessly across goal and out.
Rovers continued to make the best of the first half chances and won a corner in the 20th min which was met by Burns but his header was blocked dropping to his feet but this effort was cleared to Weir on the right but his shot ended in the side netting.
Carluke produced another chance a few mins later when Watt broke to the right and despite being fouled he managed to get a shot away which went just wide of the Gow goal.
As seemed to be the pattern for the match Lesmahagow had another chance hot on the heels of Rovers miss when they won a free kick on the left but the effort went harmlessly over the bar.
The hard working Chick McCole in the home sides midfield created the next chance when he set Smillie free on the right but his ball across goal again found no takers and the chance was lost.
As the half wore on Carluke continued to make the better chances with Weir having a free kick go just over the bar then Watt saw an effort saved after being set up by Ward before they finally took the lead in the 41st min when Burns played an excellent ball to Watt on the right and after cutting into the box beating two defenders he laid the ball in to Smillie who after a great first touch turned and played low shot in to the Gow net for 1-0 to Carluke.
Rovers had a wee chance to double this lead in stoppage time when a great move from defence through midfield ended with a Weir cross but Watt could not get enough power on his header and the effort was saved.
Half time Carluke Rovers 1 v 0 Lesmahagow.
The visiting Gow side had the better opening to the second half without threatening the home goal too much but Rovers soon began to see a few chances come their way first from a Weir free kick which was blocked then cleared and another in to the Gow area that was headed just wide by Burns.
Carluke finally got a second goal when good link up between Weir and Watt ended with the chance looking to have been lost but Watts persistence saw him block the attempted clearance with the ball spinning in to the net from the edge of the box for 2-0 to the home side in 58 mins.
The visitors got a foothold on the match in the match in the 62nd min when they broke down the right and broke in to the Rovers penalty area where a good cut back was well placed in to the home net for 2-1 to produce a good finish to the match.
Lesmahagow went with three up front for the last part of the match and pinned the home defence back for long spells but Carluke countered this by bringing the excellent Mark Haddow back and he controlled all they threw at him.
The last chance of note for the home side fell to Watt but his snap shot was saved by Gow keeper Barnes.
The visitors best chance to get level came in the 86th min when a good move ended with a shot from close range that was saved by Home keeper Jonny Grier with Scott Bellew completing the clearance.
The final minute saw a late chance for Lesmahagow when a throw in from the left ended with a shot that flashed wide of the post but the home side held firm and ended the match comfortably and ran out worthy winners on the day.
