The Texas Rangers are currently 12th in the majors in runs scored per game, at 4.43, compared to a league average of 4.26 runs per game.
The Rangers are doing this despite being 27th in the majors in OBP, 21st in slugging and 23rd in wOBA. They are also doing this despite not being doing exceptionally well in critical situations — per the Fangraphs “Clutch” stat, the Rangers are 12th in the majors this year, and are a little better than average as far as “clutch” goes.
So how is the Ranger offense doing it?
