Manager Duncan Ferguson praised his ruthless Caley Thistle side as they swept to a 3-1 home Championship victory against Ayr United.
It was a largely impressive display and it finally lifted ICT from ninth to eighth, above Arbroath on goal difference.
They are now only five points off fourth position, with games in hand on several rivals.
This was Ferguson’s fifth game in charge of ICT and followed an unbeaten start with eight points banked including last week’s 1-1 draw at leaders Dundee United.
David Wotherspoon scored his second goal in three games to give Caley Jags the interval lead and a largely deflected strike soon doubled the advantage.
On the cusp of half-time, Billy Mckay’s penalty had ICT cruising at 3-0 up.
Jamie Murphy’s spot-kick on the hour offered Ayr hope, but overall this was a fine day at the office as Ferguson’s tenure stretches to three wins and two draws so far.
Ferguson – ‘We were worthy winners’
Ferguson praised his players for picking up the pace when needed in the first half to take the game out of sight for Ayr.
He said: “I thought Ayr started better than us. We couldn’t get to the ball and put as much pressure on as we wanted to do.
“From the second part of the first half, we started connecting well and tried to get our passes off a bit quicker. We scored some good goals.
“It was a good performance and it was great to be 3-0 up at half-time.
“A wee bit of complacency maybe set in, which was a bit disappointing, because we talked about that at half-time.
“They got back into the game with the penalty, which gave us a wee bit of a problem. In the main, we were worthy winners.”
Making a move towards mid-table
And the manager was chuffed this latest win saw them move up a place in the table.
He added: “It’s good we’re now out of the bottom two. We had picked up a lot of points but didn’t seem to be moving.
“We always want more. It’s another result and now we want another one next week to push right into the pack.
“I’m really pleased with the return and with how the players are grasping my ideas and they are buying into it, which is always easier after the first result.
“To be fair, the fans also showed a lot of patience. The first 10-15 minutes were a non-event with injuries but, when we got our passing game going, we showed how good we can be.”
Ayr manager Lee Bullen made three changes from the team which let a 2-0 lead slip in a 2-2 draw against Queen’s Park. In came Nick McAllister, Mark McKenzie and Jay Senga for Elicha Ahui, Jack Young and Ahkeem Rose.
Ayr were forced into an early switch when defender George Stanger injured his shoulder in a fall and was replaced by Finn Ecrepont.
Inverness, who were unchanged from last week, were knocking the ball about well, but always alert to swift breakaways from their opponents, who had an air of confidence about them.
ICT swept Ayr aside before half-time
The breakthrough, however, came on 32 minutes with a crisp attack and deadly finish.
Billy Mckay swept the ball on to Cammy Harper, whose cross was moved on by David Carson then Nathan Shaw in the box and Wotherspoon was ideally-placed to tuck the ball away.
It got better for Ferguson’s team just before the break when, from a Harper ball, Wotherspoon rushed into the box and his heavily deflected shot beat goalkeeper Robbie Mutch to make it 2-0.
In first half stoppage-time, ICT extended their lead further from a spot-kick. Midfielder Charlie Gilmour was running into the box when he was tripped by Paddy Reading.
Referee Iain Sneddon pointed to the spot and Billy Mckay slammed home his fourth goal of the season in all competitions by sending Mutch the wrong way.
Ayr were back in the game on the hour mark when Murphy netted from the spot.
The penalty was won when home keeper Mark Ridgers, in his 250th appearance, brought down substitute Ahkeem Rose as he nipped into the box.
The visitors had the bulk of the play, but could not find a way through again and was a successful day for confident Caley Thistle.
ICT return to action this coming Saturday with a trip to Dunfermline Athletic, a match switched from October 31.
