Chances were few and far between at Bloomfield Road
By Nabil Hassan
Blackpool stayed out of the bottom three on goal difference with three games left to play after a goalless draw with FA Cup finalists Stoke.
Stoke striker Kenwyne Jones had the best chance of the game but fired wide of an empty goal before the break.
Matt Phillips produced a low, near-post volley for Blackpool but was denied by Stoke keeper Asmir Begovic.
At the other end Matt Gilks did well to keep out Glenn Whelan's 25-yard strike and a Jones header to secure a point.
Blackpool looked to be heading into the relegation places but Leighton Baines's late equaliser from the penalty spot for Everton against Wigan kept them fourth from bottom, with a one goal superior goal difference than the Latics.
Holloway pleased by Blackpool resilience
But both north west clubs could still go down because West Ham and Wolves, currently the bottom two, both have a game in hand.
And with away trips to Tottenham and Manchester United among their three remaining fixtures, Blackpool are in a precarious position after a rollercoaster debut season in the Premier League.
Ian Holloway's men started brightly, pressing Stoke and forcing them into mistakes, but for all their endeavour they were forced to rely on scraps with first DJ Campbell and then Phillips having half chances that never really threatened the Stoke goal.
Soon after, Charlie Adam was caught on the head by the boot of Stoke defender Robert Huth who appeared to fortunate to escape without any kind of card as referee Mark Clattenburg gave him the benefit of the doubt.
Unsurprisingly in difficult conditions, Rory Delap's first long throw caused Gilks problems, who flapped at the ball, allowing Huth to shoot goalwards, but the danger was easily cleared by Stephen Crainey.
Blackpool continued to press, but could not find the killer pass with Stoke were unusually nervy at the back.
The hosts' best chance of the half fell to Neal Eardley, but he sliced well wide after good link-up play between Campbell and Phillips.
Stoke always looked dangerous on the break though and only a last-ditch tackle from Ian Evatt prevented Jones from bursting through on goal.
But on the stroke of half-time Jones did find a way through, finding himself one on one with Gilks, but after rounding the keeper he fired wide of an empty goal.
It was a woeful miss from the forward who was hoping to become the first Stoke player to score in four consecutive Premier League matches.
Blackpool started the second half brightly and Phillips was denied an opener by Begovic after he directed Adams' low front-post corner towards goal on the volley.
One point should have been three - Pulis
Soon after Blackpool's Keith Southern's saw his side-foot from 20 yards fly just wide of the post after it deflected off Campbell.
At the other end, Whelan forced a fine save from Gilks who turned a 25-yard shot behind for a corner at full-stretch, but the effort seemed to reinvigorate the visitors who enjoyed their first sustained period of pressure.
Jones had another chance to break the deadlock but again found Gilks in the way as his point-blank downward header saved by the feet of the Blackpool keeper.
Shawcross and Adam then had a coming together that left Blackpool's skipper feeling more than a little groggy as the hosts started to run out of ideas.
Blackpool fans appealed for a penalty when Campbell got in a tangle with Whelan in the box, but Clattenburg waved play on, and David Vaughan tried a drive from distance which flew over.
With time running out, Blackpool sent on Luke Varney and Sergey Kornilenko, but it was Stoke who looked the more likely to score, with Whelan firing wide from 20 yards.
Both had late half chances but it ended goalless, the first match Blackpool have failed to score at home this season.
Blackpool boss Ian Holloway:
"I think this proves that we have come out of our doldrums. We have taken on a really good side at our place and kept a clean sheet.
"Their defence was slightly better than our attacking options today, so well done to them for nullifying us.
"We've lost a record [scoring in every home game], but we've gained something - we've kept a clean sheet in the Premier League at home [for the first time].
"Kenwyne Jones should probably should have been the match-winner, but from my point of view, I think that is the tide turning for us."
Stoke City boss Tony Pulis:
"Great strikers score great goals, but they do miss chances - and chances as easy as that.
"But Kenwyne has been fantastic for us and there will be no problems with him.
"Obviously it would have given us a great lift going in at half-time, but we also had opportunities in the second half which, on another day, could have dropped for us.
"Glenn Whelan had a couple of opportunities which I thought were very close, but Blackpool are fighting for their lives and you have to give them a lot of credit."
