Sprint Speed Changes: Lots of Guys Out of Shape

Some previous research, including my own, has pointed to changes in Sprint Speed being a sign a player’s talent has changed. I decided to investigate changes from 2019 to 2020 to find who could be struggling and why. Many hitters are experiencing a drop and just a few are up.

In some way, the following information should be picked apart for a longer research article with some miraculous/groundbreaking/made-up claim that batters came to this season out of shape and that is why offensive production is down. I don’t care. All I want to know is who are the hitters who could be breaking out or down. Figuring out why is for the offseason. It’s now time to wins leagues.

For this study, I matched up hitters with at least 50 plate appearances in 2019 and 2020. Additionally, they needed a Sprint Speed value at Baseball Savant. In all, 244 hitters made the cut. In the original study, hitters started seeing OPS changes around a 0.5 mph change in Sprint Speed. Just a reminder that the league-wide offense is down (-23 points of OPS, 758 to .735) but not close to enough to explain some of the changes.

Sprint Speed Changes Relating to OPS Changes
Change in Sprint Speed Median OPS Change
-1.0 or more -.070
-0.9 to -0.5 -.059
-0.4 to 0.4 -.017
0.5 or more .064

All the players with similar Sprint Speeds are close to the league-wide drop (17 points vs 23 points). The production difference is quite drastic when the ends are compared as seen by a 130 point swing in OPS. The difference is the same as going from Mookie Betts (.892 Steamer projected OPS) to Cesar Hernandez (.762).

Enough of the brackground crap, here is the list of hitters starting with a few of the slowest runners.

Sprint Speed Improvers

Jesse Winker 384 25.6 .830 64 26.3 1.196 0.7 .366
Jesus Aguilar 369 23.5 .714 72 24.2 .813 0.7 .100
Stephen Piscotty 393 26.0 .720 76 26.6 .784 0.6 .064

Donovan Solano 228 25.9 .815 86 26.5 .975 0.6 .159
Jean Segura 618 27.5 .743 64 28.1 .770 0.6 .027
Eduardo Escobar 699 27.6 .831 93 28.2 .584 0.6 -.247
Kyle Lewis 75 27.1 .885 104 27.7 .945 0.6 .060
Matt Kemp 62 25.4 .493 56 25.9 .774 0.5 .281

That’s it for the 2020 improvers. Besides Ramos and Escobar, these hitters have improved their production. In the case of Escobar and Ramos, both have underperformed their xwOBA by at least 50 points.

And now for the players on the other end of the spectrum. Those in this long list has lost over 1 mph from their Speed Speed (I’m ignoring the -0.5 to -0.9 decliners for now to shorten the list).

Some of this season’s biggest disappointments are included. Gary Sanchez. Rafael Devers. Vladimir Guerrero Jr. Jose Altuve. Christian Yelich. I’m not hand picking out names. There are almost as many hitters down 200 or more OPS points (18) than all those who improved (22).

So what can fantasy owners do with this information now? For one, it can help point to possible physical injuries. For example with Devers, his walks, power, and Sprint Speed are down while his strikeouts are up. He’s just not right and his stats need to start trending in the other direction for him to get out of this funk (.603 OPS).

Sprint Speed is just one of several factors to consider when evaluating a player but for something that should be unrelated to hitting, it’s a great indicator of who may be struggling. Just one tool of many to use.
