Match ends, Dundee United 1, Inverness CT 0.
Dundee United kept pace with Ross County at the top of the Championship thanks to Nick Clark's penalty against Inverness Caledonian Thistle.
The only goal of the game coming midway though the second half after Peter Pawlett was hauled down by Brad McKay.
Clark sent Mark Ridgers the wrong way for his fourth goal in five games.
United were reduced to 10 men for the last 20 minutes when Pawlett was shown a red card for a challenge on Coll Donaldson, but they held on.
Donaldson came closes to an equaliser with a deflected shot that was tipped over the crossbar by goalkeeper Benjamin Siegrist.
The hard-fought but deserved win lifts United three points above Ayr United into second place after Ian McCall's side lost 3-2 away to County, who retain a five-point lead.
Dundee United head coach Robbie Neilson: "I thought the first half we played well but couldn't get the ball over the line.
"It's massive for us. It takes us a step further and now second in the league."
Inverness Caledonian Thistle manager John Robertson: "I'm disappointed. I thought United started very well. Coming down the slope, they got at us with good chances, but then we settled.
"We changed our system a bit tonight by playing a diamond in there just to upset them."
