AYR won't get their fill of Irn-Bru but can surge eight points clear at the top of the Championship today.
Ian McCall's men should take advantage of Ross County's involvement in the “diddy cup” by beating Morton and opening up a significant lead.
United were well backed to win the league at 66-1 at the start of the season and some bookies will be getting worried but their biggest threat could be Dundee United who under unbeaten new boss Robbie Neilson.
The Tangerines, five points off the pace, are 9-2 at Ladbrokes with Ayr 3-1 and County hot favourites at 11-10.
Ayr dropped their first home points last week with a 1-1 draw against Queen of the South but should see off a Morton side who have had a mixed bag of results since Jonatan Johansson took over.
In recent weeks they've lost 5-0 at Ross County, beaten Partick Thistle 5-1 then crashed 2-0 at home to Alloa.
Ayr to win and both to score for the third time this season returns 13-5 at bet365 and top scorer Shankland is 11-5 with McBookie to break the deadlock.
Fourth-place Inverness could get into the title mix if they turn draws into wins. They ended a run of seven stalemates in a row by beating Partick Thistle 1-0 and face a tough test at QoS.
In League One unbeaten Arbroath have stormed into a 10-point lead at the top and tempt at 10-11 with bet365 to win at Brechin.
Could be goals too. Brechin's last five have totalled 19 with 17 in the last four meetings at Glebe Park.
It was 2-2 when they met earlier in the season so consider Arbroath and over 2.5 goals at 7-4 with BetBright.
Raith let me down last week at East Fife but should bounce back to win at Stenhousemuir and are 19-20 with Unibet.
In League Two Berwick looked to be under-rated at home to Albion Rovers. The Wee Rangers ended a run of three defeats with a superb 4-2 win at Elgin while Rovers have lost five in a row after beating Stirling for their only win.
Berwick are five points above their drop rivals and beat them 5-3 at Cliftonhill earlier in the season.
In the Irn-Bru Cup it could be the end of a great run for Motherwell Under-20s at home to Ross County who are just 1-3 at bet365 so no value there.
Championship side Alloa are 47-50 at Marathonbet to win at League Two Edinburgh City who have faltered in the past couple of weeks.
- Ayr or Ayr -1
- Shankland to score
- Inverness draw no bet
- Arbroath & over 2.5 goals
