CELTIC are closing in on seven in a row but first they want to make it 10 in a row.
Games between the pair have been tight this season – 3-2 and 2-0 to Celtic as well as a 0-0 draw.
In the previous meeting many fancied Rangers but they lost with 10 men and while they're not playing well Celtic seem to be able to get the job done.
They won both semi-final meetings between the clubs last season and are a best 4-5 at Marathonbet to win in 90 minutes and 4-11 with William Hill to reach the Final.
Rangers are 3-1 at Marathonbet and 11-4 at McBookie to qualify while a draw after 90 minutes pays 3-1 at Marathonbet.
Rangers star Alfredo Morelos missed a snip to earn a point in that 3-2 defeat and is 15-2 with William Hill to break the deadlock.
Both to score has a chance of coming up at 8-11 with Betfred as both sides are prone to making defensive boobs.
The other semi-final isn't easy to call either as Aberdeen face a Motherwell side who beat them easily in the Betfred Cup quarter-finals.
In the league the Dons have the edge with three wins to one this season including a comfortable 2-0 success at Fir Park 11 days ago.
A lot has been made of the absence through suspension of Aberdeen trio Graeme Shinnie, Kenny McLean Shay Logan and it's down to Derek McInnes to replace them well.
Despite the ban blows I reckon Aberdeen will edge it and they are a biggest 23-20 at William Hill to win in 90 minutes.
Well are as big as 73-25 at Marathonbet while a draw pays 47-20 with the same firm.
There is one game in the Premiership with Kilmarnock travelling to Hamilton.
As has been the case in recent weeks Killie are underestimated with Sky Bet going a best 17-20.
Killie haven't visited the SuperSeal this season but are unbeaten in seven on Accies' plastic and should edge a side who have suffered four defeats in a row.
In the Championship St Mirren have a second chance to lift the title after fluffing their lines at Dundee United in midweek.
There will be a sell-out crowd in Paisley for the visit of second-placed Livingston and I reckon the Buddies will get the job done at 21-20 with Black Type having lost just once at home in the league this season.
Two points separate Dunfermline, Dundee Utd and Morton in the race for the other two play-off places. The Pars have a gimme at home to Brechin who have lost every away game.
United are 19-20 at Black Type to beat Falkirk at home while Morton should see off QoS at 21-20 with Black Type.
In League One Ayr need four points to clinch the title and should get three of them at home to Stranraer. They've won three out of three against the Blues this season and scored 11.
Again I'm on Ayr and over 2.5 match goals at 3-4 with Ladbrokes.
Raith have won three out of three against Queen's Park, netting 10, and are 4-11 at McBookie to beat the amateurs again.
Montrose are three points clear of Peterhead in League Two and the top two meet the bottom two today.
The value is with Montrose who are 1-2 with William Hill to beat Berwick while Peterhead are 4-11 at Marathonbet at home to Cowdenbeath who are almost consigned to the relegation play-offs.
