On May 2, I wrote about Quality Starts as Baseball Prospectus. A lot of people deride quality starts, which are defined as a starting pitcher going six or more innings while allowing three or fewer runs. I conclude that quality starts are, in aggregate, very well-pitched games. Scroll down to the end of the article for an enlightening comparison.
On May 12, also at Baseball Prospectus, I explored whether there are some hitters who consistently perform better with runners in scoring position. Short answer: It doesn't seem that way. Longer answer: Try flipping a coin six times.
On May 16, I wrote about the Pirates' and Reds' proclivity for hitting one another's batters with pitches at Baseball Prospectus. They do it a lot, but there's not a lot of evidence that it's a case of eye-for-an-eye retribution (though 2016 may be different).
On May 17, I initiated my Trailing 30 feature for 2016 at Banished to the Pen. Among other things, I found that as of that date, there were three Pirates starters among the bottom five for ERA over the past 30 days.
