A brilliant double save from Niall Burdon late in the game earned Shelbourne their first point of the season as they frustrated Shamrock Rovers in a scoreless, though immensely entertaining, draw at Tolka Park.
Champions Sligo Rovers were the only winners, though, as they remain five points clear at the top of the table and six ahead of title favourites Rovers, who have now played out three 0-0 draws in their opening four games.
Excellent throughout, former Ireland youth international Burdon won the man-of-the-match award chiefly for his main stops which came in quick succession in the 83rd minute.
First the 20-year-old French-born keeper bravely raced from his line to block Ronan Finn’s point-blank shot. Seconds later he was there again, diving to his left to touch away with one-handed from substitute Mark Quigley’s volley on the turn.
Rory Patterson scored a late winner to give Derry City a 1-0 victory at Cork City to see the Candystripes go second in the table.
Cork substitute Adam Rundle handled inside the area in the 89th minute at Turner's Cross. And though Patterson's spot kick was parried by keeper Mark McNulty, the striker followed up to scoop home the rebound.
Drogheda United missed a penalty but still came from a goal down to beat Bray Wanderers 2-1 at Hunky Dorys Park.
Jason Byrne rifled home from distance to give Bray a 15th minute lead. Ten minutes later Darren Quigley dived the right way to save Drogheda striker Declan O'Brien's weak penalty to keep Bray ahead.
Byrne missed a one-on-one with Gabriel Sava early in the second half before Drogheda levelled on 55 minutes direct from an Eric Foley free kick.
Ryan Brennan then won it for Drogheda on 79 minutes, heading home Shane Grimes' cross.
