But now we have Statcast. The new technology that collects data on the position and velocity of the ball and the players on the field is beginning to change what we know (or thought we knew) about all sorts of things — pitching included. And that’s raising new questions about how much effect a pitcher can have on a ball once it’s put in play. The answer might be: a lot.

Don’t want to get hurt, stop throwing so hard.
As you can see these results are more in line with Dr. Fleisig’s results (25% Major League pitchers). I don’t think it’s unreasonable there are some differences, however. This would depend on our methods of gathering the data and how we defined what a Major League pitcher is. My definition was very loose. Basically if a pitcher came up and threw one inning, then I put him in the results. The reason why I didn’t have a stricter definition of what a Major League pitcher was was because my goal wasn’t to find the percentage of Majors League pitchers who had Tommy John. Rather it was to examine the relationship between velocity and Tommy John surgeries. This is really just an added bonus. Also, Dr. Fleisig’s goal was to see how many current pitchers had Tommy John. My results are the percentage of pitchers who have had Tommy John since 2002 and 2007. We, however, now can accurately conclude, in my estimation, that Carroll’s results were way too high and that velocity does increase a player’s chance of having Tommy John.
This can make pitcher selection now very interesting. For example, if you are trying to decipher whether to get a pitcher who throws 96 MPH who is just as good as a pitcher who throws 90 MPH, you might be better off taking the guy who throws 90. By doing that you would be reducing the odds that that pitcher has Tommy John by about 7 to 10 percent, which is pretty good if you ask me. Also if you’re a GM or in fantasy and are terrified of relievers because you think they all tear their ulnar collateral ligaments, well you shouldn’t be. Your starters are actually slightly more likely to tear their UCL. There are of course other factors to consider here but these can serve as basic general guidelines. Finally velocity does increase your likelihood of tearing your UCL, although with starters the data is a little murkier.

An interesting observation from Felipe Alou, via Pedro Martinez. I wonder how this would stand up to a higher sample.

My real purpose in doing this was to educate myself about the 30 major league rotations. If I can force myself to do this once a week—which I probably can’t, but if I could—then I would develop a stronger understanding of who was in the rotation right now for all 30 teams, who their #1 starter was, etc. I’m old; I have a hard time lodging all of that information in my head.

This may be an improvement over other metrics that are currently available. (I don’t have time to read the detailed breakdown, which I applaud them for providing, BTW.) I would think, though, better metrics for measuring pitchers are just around the corner due to Field F/X (whatever it’s called) data. With that data it should be possible to separate (and this is one of the Holy Grail sabermetric goals) fielding from pitching.

Mat Latos has dropped 15 points since the season began…
Here’s something to jazz up your baseball debates: a ranking of the top starting pitchers in the major leagues. These rankings (which include postseason performances) will be updated every morning, though we’ll show each pitcher’s score as of April 1st of each year (that’s the “Started Season” column). If you’re interested in how we put this together, read about Bill’s concept in this article.

Sorry, it’s the right adjustment.
“A hitter can take as many swings as he wants,” Butcher said. “Pitchers are only allowed a certain amount of throws per day. So when you start tinkering with the strike zone, I think it’s a longer adjustment process for a pitcher to go through. I think it would be a tough adjustment and the wrong adjustment for the league.”

McHugh threw 47.1 innings with the Mets and Rockies between 2012 and 2013, and his pitch selection looked something like this: 56 percent fastballs, 39 percent breaking balls (curve ball and slider), and five percent change-ups. McHugh relied primarily on his hard stuff, complemented it with some breaking balls, and threw in the occasional change-up, a pretty standard plan of action for a starting pitcher.
The Houston Astros, however, saw something more. Something about those breaking balls caught their eye: They had a ridiculous amount of spin on them. This discovery was brought to light in a recent piece in Business Week:
