Winning Advantage?

Stockfish and other engines give White an advantage of 1.7 to 2.3 pawns, but cannot suggest an approach superior to that played in the game.

White to move

52.Rh7 Kb6 53.Kb3 Ka6 54.Rc7 Rg8 55.Ka4 Kb6 56.Rg7 Rf8 57.Rg6+

Black to move

57...Kxa7 58.Ka5 Kb7 59.Rg7+ Kb8 60.Kb6

Black to move

Black saw that he had reached a Philidor Position and easily held the draw with mere seconds remaining on the clock.

Did White have another means for securing a win that the engines might suggest if allowed to "think" longer?

    Seems to me that

    1) White can't make progress without giving up the a-pawn.
    2) All scenarios with just the b-pawn are dead drawn.

    Black just shuffles the rook on the back rank. Looks 1/2-1/2 to me.
