Over at Camden Chat, I discussed how poorly the 2014 Orioles hit when the sun was shining vs. when the owls were hooting and whether fans should expect that to continue in 2015:
…The Orioles had a wOBA of .310 in day games last year, 19 points worse than their night-time wOBA of .329. That’s a lot of offense to “lose” over the course of a season. In fact, since the average team had a wOBA of .310 during the day last year, you can say the Orioles were an average offensive team when the sun was shining. At night though, they turned into Mr. Hyde: their .329 wOBA was far and away better than the major-league average of .312.
