After Soto's double in the 9th inning he worked to get Iggy's pitch grips from 2B, trying to distinguish between CH vs FB. It looks like he got them and hopped at 2B to relay to the hitter a CH was coming. Semien did not swing at some good CHs b/c of that and walked as the potential tying run. Iggy either adjusted, Soto got it wrong or Alvarez got caught in between. Either way it didn't cost the Braves but it got too close.
