Spiders Web was a last gasp winner of a thrilling JT McNamara Ladbrokes Munster National at Limerick.

There was a sprint to the first fence, where Black Scorpion and Kilcarry Bridge led from Full Cry.

Heading away from the stands, Kilcarry Bridge led over the third from Black Scorpion and Full Cry, with Kylecrue and Rogue Angel next.

At the back of the field, Blast Of Koeman was a faller.

Heading down the straight, Kilcarry Bridge and Black Scorpion continued to set the pace, but Full Cry then went on as they jumped the fence in front of the stands, with Kylecrue also joining issue.

Kylecrue pressed on down the back, but Black Scorpion then hit the front from Full Cry.

As the field took the final open ditch, Black Scorpion led but it was a wide-open race still, with Full Cry, Kylecrue and Rogue Angel within striking distance.

Turning for home, Black Scorpion led, with Na Trachtalai Abu, Rogue Angel and Full Cry all challenging.

On the outside, it was Na Trachtalai Abu who swept through and jumped the last in front, where Its All Guesswork took a crashing fall in third.

Na Trachtalai Abu pulled clear on the flat and looked destined to win, but Luke Dempsey began to galvanise Spiders Web, who had been patiently ridden to that point.

The Thomas Mullins trained seven year old, in the JP McManus silks, got going on the run-in to pass Na Trachtalai Abu late on, with Black Scorpion third and then came Alpha Des Obeaux.
