The first A’s run scored because Fuld stole his way into scoring position. There was another threat in the second because Semien stole his way into scoring position. There was another threat in the fifth because Canha stole his way into scoring position. Then in the seventh, the whole meltdown was triggered by Sogard stealing second base. That led to a sac bunt to move him to third. Having that runner on third led to all the bullpen machinations by Scioscia to try and stop that one run from scoring but ultimately resulted in several runs scoring.
If Iannetta had cut those runners down or been enough of a threat that they didn’t attempt to steal, this game could’ve gone much, much differently.
