Motherwell goalkeeper Liam Kelly saved a penalty to help his side play out a hard-fought goalless draw in difficult conditions at St Mirren.

The Scotland international parried away Mark O’Hara’s spot-kick four minutes after half-time, and despite the visitors having four one-on-one opportunities after surviving a close escape, they failed to find the net.

Motherwell’s winless run in the cinch Premiership extended to 14 games and they now occupy the relegation play-off position, while St Mirren dropped to fourth in the table below Hearts on goal difference.

Both teams made one change from their last outing. For the hosts, Keanu Baccus replaced Caolan Boyd-Munce, who failed to make the squad, while Harry Paton returned to the Well starting line-up with Jon Obika dropping to the bench.

Blustery conditions looked set to play a major factor in proceedings and they were evident as Georgie Gent’s cross in the early exchanges swung across the St Mirren penalty box and out for a throw-in.

Saints passed up a glorious opportunity to break the deadlock after 12 minutes when Thierry Small’s low cross broke for Greg Kiltie who sliced an effort that sailed inches too high.

Just minutes later, Kelly, who took the blame for St Johnstone’s goal at Fir Park last weekend, looked uncertain when tipping Jonah Ayunga’s innocuous looking header over the crossbar.

The wind was drastically impacting the quality on show, with neither side quite able to get to grips with the difficult conditions in the opening 45 minutes.

St Mirren were awarded a penalty four minutes after half-time when Stephen O’Donnell was adjudged to have handled Ayunga’s cross.

O’Hara stepped up to take the resulting spot-kick but he was denied as Kelly parried his poor effort away before the Steelmen defence scrambled the ball clear.

Motherwell had yet to work the Saints keeper, though they did have a rare glimpse of goal as Paton’s strike from outside the box flashed wide of the target.

Zach Hemming was finally called into action after 58 minutes as Blair Spittal’s free-kick found Gent unmarked inside the box but he could only head the ball into the grateful arms of the home keeper.

The game was beginning to open up and it took a good save from Kelly to turn Small’s curling shot round the post, before the visitors somehow failed to take advantage of two glorious chances to break the deadlock.

Mika Biereth skipped through the Buddies midfield and released Spittal, who twisted past Alex Gogic before somehow firing wide.

The Arsenal loanee was involved again a minute later after slipping the ball through to Callum Slattery, but the midfielder hit the deck under pressure from Gogic and saw his claims for a penalty dismissed following a VAR check.

Chasing an elusive victory, Motherwell began to look the much more likely to find an opener and it took some smart goalkeeping from Hemming to deny the onrushing Biereth, who had sprung the home offside trap.

Motherwell manager Stuart Kettlewell introduced Theo Bair and Oli Shaw in search of a winner and Bair almost made an instant impact when he found himself bearing down on goal, only for his powerful shot to be kept out.

It was the fourth one-on-one opportunity for the away side and yet again they were unable to find the net as they had to settle for their fifth draw in seven league matches.

Caolan Boyd-Munce hit a spectacular first goal for St Mirren to send the Buddies past Motherwell and into the Viaplay Cup quarter-finals.

The former Northern Ireland Under-21 international replaced injured captain Mark O’Hara ahead of the previous weekend’s win over Dundee, which sent St Mirren top of the cinch Premiership overnight.

And the 23-year-old again helped alleviate the absence of O’Hara as he proved the difference in a 1-0 victory in Paisley.

Boyd-Munce lit up a scrappy start to the game in the ninth minute. Ryan Strain made some progress as he cut in from the right before the ball broke for the former Middlesbrough and Birmingham midfielder, who fired a first-time effort into the top corner from 20 yards.

Motherwell improved after a poor first half but did not do enough to prevent only their third defeat in six months under manager Stuart Kettlewell.

The visitors, with Davor Zdravkovski making his first start in midfield, were sloppy in possession for spells in the first half and struggled to get men forward to support their strikers as they played into a strong wind.

Keanu Baccus twice threatened for St Mirren after Motherwell lost possession well inside their own half.

The visitors’ first real threat came early in the second half when Theo Bair took in Stephen O’Donnell’s pass with his back to goal and fired a shot which Zach Hemming tipped over at full stretch.

Kettlewell brought on Lennon Miller and Mika Biereth before the midway point in the second half as the game became more open.

Good work from former Motherwell striker Mikael Mandron sent Conor McMenamin clean through but he delayed his shot and Dan Casey got back to block the effort.

Motherwell somehow got a three-on-two break moments later, but Callum Slattery’s pass did not allow Biereth the best angle to shoot and the Dane’s driven ball across the face of goal just evaded Conor Wilkinson.

Kettlewell switched tactics in the 76th minute as forwards Joe Efford and Mark Ferrie replaced wing-back O’Donnell and Wilkinson.

Former Well manager Stephen Robinson responded by putting on ex-Fir Park defender Charles Dunne and St Mirren saw out the final stages without serious threat.

Motherwell defender Shane Blaney had an opportunity to show his prowess from a 25-yard free-kick but the Irishman fired well over and Olutoyosi Olusanya had two great chances to make it 2-0 in stoppage time. The substitute was denied by Liam Kelly and then hit the post on the breakaway.

Caolan Boyd-Munce has agreed a one-year contract extension with St Mirren, who have confirmed star striker Curtis Main, Charles Dunne, Joe Shaughnessy and Richard Tait will all move on.

The 23-year-old midfielder joined Saints in March on a deal until the end of the season and the club has taken up the option to extend that until the summer of 2024 with an appearance-based option for another year.

The Northern Irishman – who began his career at Glentoran and had spells at Birmingham and Middlesbrough – made three appearances for the Buddies last season with his first start coming in Saturday’s match against Rangers at The SMiSA Stadium.

Manager Stephen Robinson told stmirren.com: “Caolan was never going to come into the first team fold straight away because he hadn’t played for a long time.

“What we could see three months ago, he is now starting to achieve. Sometimes, that gamble is worthwhile.

“He’s different from what we have. He will find passes and put people through on goal as he gets fitter and stronger.

“We believe that come August/September, he has a real chance of starting games for us and pushing on. There’s so much more to come from him.”

“The option for a different type of midfielder who is similar to an Ethan Erhahon (who left for Lincoln in January) makes us stronger as a squad.”

Robinson, who has 20 players under contract for next season, did not expect 31-year-old striker Main, a key player since joining from Shrewsbury two years ago, to extend his time in Paisley.

The former Morecambe and Motherwell manager will also have to bolster his defence this summer.

Club captain, Shaughnessy, 30, joined the Buddies from Southend in 2020 and was out of the team earlier in the season.

Fellow centre-back Dunne, 30, arrived from Motherwell two years ago while full-back Tait, 33, also signed from the Steelmen in 2020.

In a general squad update, the Buddies website said: “Offers were made to Charles Dunne, Curtis Main and captain Joe Shaughnessy, but all three have decided that their futures lie elsewhere.

“With over 250 combined appearances between them, we thank them immensely for their respective contributions to St Mirren and wish them the very best in their new challenges.

“Richard Tait also departs after almost three years at the club where he made 87 appearances and scored three goals. We sincerely thank Richard for his contributions and wish him the very best in whatever comes next.

“Tony Watt and Thierry Small have returned to their parent clubs, Dundee United and Southampton, respectively. We thank them for their time at St Mirren and wish them all the best for their future.

“An offer to Youth Academy graduate Jay Henderson remains on the table.”
