Dublin's quest for a seventh All-Ireland in a row is over with Mayo headed for the final.
After a slow start, it looked like Dublin were going to pull away.
However, Mayo fought their way back into the game and a last gasp 45 from goalkeeper Rob Hennelly sent the game to extra time.
James Horan's men continued that momentum and raced into a three-point lead which they held until the end.
