Caley Thistle extended their lead in second place to four points with a fully deserved 2-0 Championship win over Dundee.
Inverness produced an excellent display at Dens Park in which they limited the Dark Blues to little threat, triumphing thanks to first half goals from Aaron Doran and James Keatings.
The result means Inverness are now six points ahead of James McPake’s men, who were leapfrogged into third place by Ayr United.
John Robertson rang the changes from the side which went down 1-0 to Arbroath the previous weekend, with skipper Carl Tremarco, James Vincent and Nikolay Todorov drafted in to replace Jamie McCart, David Carson and Jordan White.
Inverness showed early signs of looking like their usual attacking selves, with a neat move seeing Miles Storey’s delivery nodded over by Todorov after three minutes.
Storey was looking a particular threat down the right flank, with another cross setting up Tremarco whose header was held by Jack Hamilton.
Keatings was next to threaten for the visitors on 11 minutes, with a free-kick from a wide right position which Hamilton did well to beat to safety.
Inverness were not to be denied a deserved lead on 17 minutes, when Shaun Rooney was released down the right by a long ball from Kevin McHattie, with the full-back’s low delivery met by Doran who thumped the ball high past Hamilton from 14 yards.
Inverness took just seven minutes to double their advantage, breaking to great effect from a Dundee corner. The ball once again broke for Rooney, whose ball forward was met by a deft touch from Keatings to take it past Jordan Marshall, setting up the attacker to drill low past Hamilton.
It capped a great start by the Highlanders, who could have added a third when Storey linked well with Doran before powering a low drive into the side netting.
Dundee had little to show for their efforts, with Graham Dorrans seeing a strike from the edge of the box blocked by the Caley Jags rearguard.
Mark Ridgers was called upon for the first time on 49 minutes to make a diving save from Jordan Marshall, while the Inverness goalkeeper also comfortably held on to a long-range Jordan McGhee strike.
At the other end, Doran was denied a second goal when his curling free-kick was well held by Hamilton.
Dundee made advances on the Inverness goal, with Ridgers tipping over Paul McGowan’s header and Marshall seeing an effort deflected wide, but the visitors’ lead never looked threatened.
