I actually think the series was lost and won on two defensive plays. For the Royals it was the amazing catch of Howie's drive by Aoki. It got past Cain, which few hits had. If Aoki doesn't make that play, two runs score in the sixth inning, and there is no extra innings. Angels win game one. The other is Trout's misplay of Gordon's hit. It would not have been an easy play, but good defense was needed to neutralize the Royals as they were neutralizing the Angels. If Trout makes that catch, the Royals don't score their second run, and again no extra innings and the Angels win game one. I'm not sure how that might have changed the series, but I think the real difference for the Royals overall was defense rather than offense. Angels made some key mistakes that hurt them--others such as Iannetta's throws--yikes.
