The Astros played much better D, and had much better clutch hitting. Pitching didn’t kill the Dodgers. Their bats and gloves killed them.
Over 7 games it was very even
Astros .230/.297/.467 34 R, 15 HR
Dodgers .205/.290/.393 34R, 10 HR
Astros allowed 1 unearned run, Dodgers allowed 2.
The Dodgers won G 1, 4, 6 somewhat "comfortably" The Astros won games 3 & 7 somewhat "comfortably".
The difference in the series was the crazy games 2 & 5 both went to the Astros. The late HR barage against the Dodger BP in game 2. and the 13-12 game started by staff aces Kershaw and Keuchel where Kuechel got smacked around and Kershaw was unable to hold leads of 4-0 and 7-4.
