Earned run to the wrong pitcher at the Olympics?

I’ve just watched the olympic baseball match USA vs Israel (8-1) and after reading the boxscore, I probably found an error by the official scorer. All happened in the top of the 8th inning; that’s what it is reported by the play-by-play of the game:

USA Inning 8
– FILIA Eric singled to right field.
– LEICHMAN Alon to play pitcher for ISR substituting LIPETZ Shlomo.
– Ball. FILIA Eric stole second base, FILIA Eric to second base.
– KOLOZSVARY Mark grounded out to first base, unassisted. FILIA Eric to third base.
– STARLING Bubba grounded out (1 RBI), pitcher to first base. FILIA Eric scored.
– ALLEN Nick flied out to center field.

I suppose the earned run is responsability of Lipetz, but the official scorer imputed the ER to the substitute pitcher Leichman (who retired the 3 batters faced), I missed anything there?
