The Elusive Clutch Hitter–Part II by Scott Lindholm February 22, 2011 I made some mistakes, some careless, some unknown, with the charts included in my post titled “The Elusive Clutch Hitter,” and I wanted to clear them up. The first correction shows the batters in my sample who had an increase of at least 10% in batting average with runners in scoring position (RISP) vs. no runners in scoring position (nRISP). It was my intention to do this all along–indeed, I had posted earlier and woke up the next day and realized I had compared RISP batting average with career batting average, which would cause an overlap in the data. I trashed that post prior to it being published, but it appears I made the same mistake, at least with this particular chart. Here’s the corrected chart: From FanGraph Graphs The columns on the left are nRISP situations, and the right are RISP situations. with the difference calculated as (rispBA-nrispBA)/(nrispBA). If I’ve amalgamated the data correctly (and I made every attempt, but errors will happen), adding the nRISP and RISP AB and hits columns should equal the player’s career totals. I have no idea how I got the years wrong in the initially published chart, but the same essential data is presented. This next chart shows those players who had at least a 10% decrease in RISP batting average. This chart is essentially unchanged from the initial one, other than also making sure I was comparing RISP vs. nRISP hitting and not comparing to career hitting. From FanGraph Graphs The only thing I’ll add here is something I forgot to state in my original post, which is that I’ll go so far as to say that most of these hitters are sample size issues, since most of these are current players. The other thing I failed to mention in my original post is that all errors are mine, although as I amalgamate the mounds of data available from the various sorts, I try my hardest to be sure I’m accurate. Thanks for all the comments so far.
