Goals from Leigh Griffiths and Callum McGregor moved Celtic four points clear at the top of the table after a nervy final five minutes.
The Hoops had a few openings in the first half but were limited to shots from distance as Partick Thistle were compact and organised in defence.
The best came from Nir Bitton, who’s fizzing shot went inches wide of the top right-hand corner after 40 minutes.
Celtic took a well-deserved lead through Griffiths just before half-time for his 35th goal of the season.
Gary Mackay-Steven’s terrific cross was coolly controlled by Griffiths who composed himself before firing the ball at Tomas Cerny, who couldn’t prevent the ball crossing the line.
On 54 minutes Callum McGregor doubled Celtic’s lead with a cool finish with his right foot.
Erik Sviatchenko gave Thistle a glimmer of hope after pulling back Steven Lawless and gifting them a penalty with five minutes remaining.
Here are the player ratings from today’s game.
Craig Gordon 6.5/10
Made a good save from a long range shot at goal as Celtic failed to clos the ball down. Made himself big to deny Thistle another chance on goal just before the half hour mark.
Mikael Lustig 6/10
Quiet start to the game at right-back and didn’t get forward too many times to overlap Commons and allow him to move into a more central area. Came close to giving Celtic the lead from a header. Got forward more in the second as Celtic put the Jags on the back foot and almost picked out Commons and winning the ball inside the box.
Erik Sviatchenko 5.5/10
Untroubled in the opening 20 minutes and didn’t take the ball out from the backline too many times. Had a few wayward and poor passes in the game and is probably more suited to the left side of two centre-back positions. Clumsy challenge and gave Partick Thistle a cheap goal and a chance in the game.
Charlie Mulgrew 7/10
A solid game alongside Sviatchenko and covered well for Tierney on two occasions in the opening 10 minutes. Took the ball out from defence most of the time and looked composed and assured for Celtic.
Kieran Tierney 7.5/10
Got forward well but the final ball was lacking early on. It didn’t matter whether he drove inside or went down the line he beat his man and caused problems. His defending was terrific once again and made countless tackles and interceptions.
Callum McGregor 7/10
Played a good low cross to Griffiths for Celtic first chance of the game. Good through ball to Commons who almost picked out Mackay-Steven. Celtic’s best player in the opening 15 minutes as they settled into the game. Lovely solo run and finish with his right foot.
Scott Brown 5.5/10
Sat in front of the back four and allowed Bitton and McGregor to go forward. Lacked that aggression that is usually so prominent in his game and allows him to control and dominate the midfield. Dug in throughout the second half and but in a better performance.
Nir Bitton 6.5/10
Started well in his first game back into the team and drove forward with the ball to start a Celtic attack. Bitton just needed to be a bit sharper with his passing in the final third. Had a few shots from distance and saw one effort go just wide and should have tetsed the ‘keeper better 10 minutes from time. Kept up the intensity which was good to see having missed three games.
Kris Commons 6/10
Linked up with McGregor on a few occasions and had a good chance from the edge of the box after a one-two with Griffiths but leaned back and fired over the bar. Had another chance just before being replaced by Kazim-Richards but failed to test the ‘keeper and opted to lay it off to Griffiths.
Leigh Griffiths 7/10
Good diving header that forced a good save from Cerny after seven minutes. Did see the ball too many times and kept moving into an offside position as Thistle looked to keep a high line. Forced to have a few shots from distance as Celtic struggled to create chances. Good first touch to settle himself and volleyed home his 36th goal of the season. Massive chance to kill the game but his shot was straight at the ‘keeper.
Gary Mackay-Steven 6.5/10
Almost got on the end of Commons’ pass in front of goal to give Celtic the lead. Fairly quit in the game otherwise and didn’t look to the ball and drive at two Thistle players that were booked. Great ball into the box got Griffiths who did all the work to find the net and played a part in the second to find McGregor in space on the right wing.
Colin Kazim-Richards 3/10
Replaced Commons with 23 minutes remaining in the game as Ronny Deila looked to assure Celtic got all three points with a third goal. Held the ball up well and brought others into play. Scuffed the follow-up effort from Griffiths’ shot that was saved by Cerny’s foot. Great first touch from Tierney’s pass and shot just wide of the far post.
Stuart Armstrong N/A
Came on for Griffiths with two minutes remaining in the game.
