By some measures, the Astros are the best hitting team in baseball. Like the 2017 team, they may end up in consideration as one of the best hitting teams of all time. In wRC+ the Astros are blowing away the rest of the league. Their 122 rating means they are 22% better at hitting than the average team in baseball right now. The next best team is the Yankees at 116. For comparison purposes, the 1927 Ruth, Gehrig, Yankees had a 126 rating.
But the Astros’ dominance in terms of park adjusted weighted on base average, a rough summary of what wRC+ means, does not translate into scoring the most runs.
