The defensive mistakes by the Yankees were costly.
The Dodgers scored their first run in the 5th after Kike got a triple and then scored on a sac fly. It probably should have been a double but Soto didn’t have a good angle on it.
Same thing happened in the 8th for their second run. Ohtani should have had a double, but they screwed up the relay throw and he was able to advance to 3rd and then score on a sac fly.
Then in the 10th, Cabrera misplayed Edman’s groundball which should have produced at least one out.
I wouldn’t blame Weaver. He got everyone he faced out, but when he came in, Ohtani was already on 3rd instead of 2nd because of the botched relay.
