Highland surged back to form, crushing a brave Watsonians side 52-7 in Inverness.
Head coach Dave Carson said: “Not only did we win in some style but with Heriots, the side just above us in National League 1, losing, we are back in the race for runners-up.
“It sets us up nicely for our Scottish Cup quarter-final game next week. It’s one of the biggest games in the history of the club. A crack at the best amateur team in Scotland.
“Our first-half attacking was just fantastic, followed by a great defensive effort when they came back at us in the second.”
The first-half tries came from Stephen Murray (2), Gordon Gregor, Seamus Ross and Rupeni Rokoduguni, all converted by stand-off Scott Fraser.
In the second half, the Myresiders came more into the game, but failed to score a point, whereas Andrew Findlater and Ian Chisholm added unconverted tries for the hosts.
Elsewhere, Caithness had a bad day on the road, crashing 45-10 at Forfar, where Strathmore had to come from behind to see off the early challenge of the Thurso side who fell badly off the pace during the 10 minutes scrum-half Kris Hamilton was in the sin bin during the first half.
Head coach Ewan Boyd said: “We must start picking up points on the road if we are to get out of the relegation area. Three sides go down. We are clear of the bottom two of Perthshire and Carrick and we need to start making inroads into the six-point gap between ourselves and Murrayfield Wanderers.
“The battle to stay up could go the last game in Perth.”
