Prior to the start of today’s games, the five NL West teams occupied the top six spots in on-base percentage. The Giants and the Diamondbacks were practically tied for number one, with .367 and .366. The Dodgers’ .359 were right behind them. At numbers five and six, the Rockies and the Padres had .349 and .348.
By contrast, three of the four AL West teams ranked in the bottom sixth: the Mariners’ .307 put them at 25th, the Angels’ .301 at 26th, and the A’s .289 at 28th. Texas had a respectable .338, which was good enough for 11th.
I doubt that these rankings will hold for much longer, but they’re interesting to note in the first 10+ games of the season.
