Oakland entered Tuesday with the worst record in baseball, at 14-26, despite being outscored by only four runs for the season. The A’s have been particularly unfortunate in one-run games, going 2-13 in those contests. In the 30-team era, no other team with a run differential of -4 or better through 40 games has had a record as bad as Oakland’s. Close company includes the 2014 Cubs (-8 RD, 13-27) and the 2000 Astros (-2 RD, 15-25).
Unsurprisingly, the length of baseball games is correlated to the number of total batters:
Thanks to the new pace-of-play initiatives, the average length of nine-inning games is down eight minutes in 2015 versus the comparable time period in 2014. The effect has been slightly stronger for games with more batters:

Earlier this week, Nick Ashbourne at BP Bronx wrote about the Yankees’ heavy reliance on sliders. As the chart above shows, the Yankees were among the least slider-happy teams five years ago, but their usage of the pitch has spiked this season to 27.0%; if they keep that pace up for the full year, it will be the highest percentage in at least six seasons (surpassing the 2013 Giants at 25.8%). However, as Ashbourne notes, slider usage is correlated with injuries, which is bad news for the already old and injury-prone Bronx.
