It's a far cry from the form shown by the Scarlets at the start of the season as Simon Easterby's men, along with Ulster, set the early RaboDirect PRO12 form.
Last time out in the RaboDirect PRO12, Scarlets travelled to Ravenhill for a first-versus-second clash but after going down 47-17, Turnbull and co now sit fifth - a measure of how tight things are at the top of the table.
Thanks in part to some impressive early season performances, Turnbull is now likely to be missing for the Scarlets while assisting Wales in the defence of their Six Nations Grand Slam.
But after finishing fifth in the RaboDirect PRO12 last term and just missing out on the end-of-season play-offs, Turnbull is desperate to avoid the same fate this time around.
"We've had some tough games recently, looking at the stats against Leinster, we made about double the amount of tackles we normally would so that tells its story," he said.
"We were a bit unfortunate against Ulster because I don't think the scoreline quite reflects the game but we let it get away from us at the end, and then Clermont are the team of the moment in Europe.
"We've had a fair few injuries of late which have made things difficult but we need to try and get back to the form we were showing at the start of the season.
"The Rabo table is very tight at the moment but we look back at what happened last year and we use that as a motivating factor.
"We need to try and keep getting those Ws on the board. We've had a tough run of games but we've now got a quite a few games at home between now and the end of the season and we need to take advantage of that."
Turnbull is certainly right when he says the Scarlets have been on a tough run - the 29-0 defeat to Clermont last time out ensured they have now won just one of their last eight matches.
But he's also on the money about the region's run in - six of their last nine RaboDirect PRO12 matches are at Parc y Scarlets.
And although the Six Nations will account for a number of Scarlets players in the coming weeks, Turnbull is convinced that Easterby and his coaching staff can steady the ship and guide the West Walians into the play-offs.
"Having Simon as coach has been great, not just for me as a back row, but for the whole squad," he added.
"He's not been retired very long and so he's very much a modern coach who has fresh ideas about the game having played it recently.
"We saw at the start of the season what we can do with those ideas and so hopefully we can push on if we can get everyone back for the last push."
