According to Sam Stein, Sam Grafton raised from under the gun. Action folded to Stein in the big blind and he moved all in. Grafton called.
Grafton was holding but was racing against Stein's . The board ran out and that was good to earn Stein the pot and secured the elimination of Grafton.
Sam Trickett also posted of his elimination on Twitter:
Was cruising in the 10k and then Bang ,lost 3 hands in 10 minutes and I am out - gutted ###37th place ...— Sam Trickett (@Samtrickett1)
So with the eliminations of Grafton and Trickett, that makes Sam Stein the last Sam standing.
