This game was played in much better conditions than last week with Nairn having the slight wind advantage in the first half.
The opening minutes did not provide much goalmouth incident at either end. However, McKenna had a shot scrambled clear by Tocher.
The Bay retaliated with a Sturton header going over the visitor’s bar following a short corner worked between Tocher and Goodwin.
The Bay had a lucky escape when Lynch who found himself back in defence lost the ball to Nairn’s Maines who then past a crossover which Park put over the bar.
Evans, in the home goal, was called into action when he had to punch clear an effort from Finnie and then scramble a lofted ball away for a corner.
The Bay went ahead after 20 minutes. Anderson worked the ball into the Nairn box and Watson latched onto the loose ball to slot the ball past keeper Duncan from ten yards.
Following further good work by Watson, Sturton put the final cross from the Bay winger over the bar.
In 37 minutes Nairn drew level. The ball broke loose in the home area and Grant made no mistake from close range. Just before half time the visitors went ahead when Grant found himself clear and again made no mistake in putting the ball past Evans.
Evans kept the Bay in the game within minutes of the restart when he made a save from point blank range from McKenna and the ball was scrambled away by the Bay defence.
The Bay were back level after 52 minutes when Nairn keeper Duncan could only help a Goodwin corner into his own net.
They went into the lead again three minutes later when Anderson’s free kick from 20 yards beat the visitor’s defensive wall and keeper Duncan to nestle in the right hand corner of the net.
Nairn, however, did retaliate with McKenna getting in a cross which went straight across the Bay goal with no-one able to connect.
K Morrison managed to get round the back of the Nairn defence only to see his cross being saved by keeper Duncan.
Evans was again the hero for the Bay when he was quickly off his line to save at the feet of Thomson as he bore down on the home goal.
McKenna again caused panic in the home defence when he found himself unmarked, however, Evans was again able to block the shot.
The Bay sealed the win with a few minutes remaining when Irvine headed home a Sturton free kick.
Again this was not a classic but the Bay ground out this result to consolidate second position in the league.
