Having picked up just two points from the past 30 available to them, Kilmarnock are in relegation form.
In fact, in Kettlewell's past 25 Premiership matches as a manager, he has won just three of them.
Kilmarnock have been in freefall since a 3-0 home defeat to Hearts in October. That loss started a wretched run of eight defeats and two draws in 10 games.
With bottom-side Livingston - who have a game in hand - just three points behind, the threat is clear.
But what do the underlying numbers say about Kilmarnock?
No team in the league has a lower average possession (38%) than the Ayrshire side, which tells you they struggle to control games.
Of course, possession isn't everything, but if you are going to need to defend for more than 60% of the time in your matches, you had best not have the worst defensive record in the division.
No side has shipped more goals than Kilmarnock's tally of 32, while going the other way their scoring rate of one per game is verging on a league low. That is a recipe for relegation.
Three clean sheets from 17 matches is also troubling, as is the fact their expected goals conceded tally is the highest in the league.
Kettlewell was frustrated after Sunday's defeat to Aberdeen as Killie had a penalty taken off them by VAR following a hand ball and then one awarded against them for hand ball.
"Everyone will point to the bad run, but people have no idea how much these huge decisions have a bearing on people's careers, their jobs," he said post match.
In the previous game he lamented "big decisions" going against them in a defeat by Rangers which saw him sent off.
Now, it will be down to former Partick Thistle boss Kris Doolan, who has been placed in caretaker charge, to improve those numbers in the interim as a weekend visit from Falkirk looms.
Following that, a confidence-stricken squad face back-to-back trips to League Cup winners St Mirren and fellow strugglers Dundee before welcoming Hibernian.
