Table of Contents
Here’s the table of contents for today’s edition of the Daily Notes.
Featured Game: St. Louis at Milwaukee, 20:10 ET
Regarding the Cardinals, Who’s Starting for Them
In terms of who’s starting for the Cardinals tonight, it’s young and prized right-hander Shelby Miller.
Regarding Shelby Miller, His Performance to Date
Regarding Shelby Miller’s performance to date, it wouldn’t be inaccurate at all to characterize it as excellent. To wit: 5 GS, 30.2 IP, 27.1% K, 8.2% BB, 45.5% GB, 3.24 SIERA, 83 xFIP-, 0.5 WAR.
Regarding Miller, His Approach
One thing regarding Shelby Miller’s approach is his reliance on just two pitches, his fastball and curve — which pitches he’s throwing a combined 99% of the time, according to PITCHf/x data.
Regarding Miller, His Approach, Part II
Writing about Miller last week, Bryan Smith “found just 14 player seasons [from the last five years] where a player’s two favorite pitches represented more than 90 percent of his total pitches thrown.” Of note: the combined ERA of those 14 players seasons is 3.71, which is lower than the author would have assumed, at least.
A Statistical Concept Which Might Apply Here
A statistical concept which might apply to those 14 players season in question is selection bias. As it is generally the case that pitchers who throw only two pitches are relegated to the bullpen, the ones who remains as starters might have to be particularly good to do so.
Another Statistical Concept Which Might Apply Here
Another statistical concept which may apply here is any of Doob’s martingale convergence theorems. How they would apply I’m sure I don’t know, but they might.
A Graph Pertaining to Shelby Miller
Here’s graph of Shelby Miller’s average velocity by start so far — which graph (a) appears to reveal a trend upwards and (b) is presented in the default Excel format:
Another Graph Pertaining to Shelby Miller
Here’s a similar graph to the one above, except with Shelby Miller’s face overlayed onto it and also a Cardinals-themed color scheme:
Other Notable Games (Including MLB.TV Free Game)
Washington at Pittsburgh | 19:05 ET ***MLB.TV Free Game***
Right-hander A.J. Burnett starts for Pittsburgh, making this table of the top-three qualified starters per strikeout rate entirely relevant:
Readers’ Preferred Broadcast: Washington Radio.
Boston at Texas | 20:05 ET
The Red Sox are second among all major-league teams by combined defensive runs saved and baserunning runs — which stat (a) isn’t a real thing, but which also (b) probably indicates something in the way of team speed and athleticism.
Here are the top five teams by that totally fabricated measure:
Readers’ Preferred Broadcast: Texas Radio.
