From watching the highlights a few times, I think that Saunders chest down was due to a shout from Craigan, atleast that's who Reynolds shouts at, with Randolph telling Saunders to use his eyes.
Hateley did really well to get the cross in for the goal and Humphreys wee knock back was superbly taken. The finish was just placed perfectly.
I think for the penalty, Phillips stumbles over his own leg before Saunders makes contact, very unlucky.
