The Rays are using some cool new technology to monitor pitchers’ biomechanics


Jeff Passan of Yahoo reports on a pretty neat new bit of tech the Tampa Bay Rays are using. It’s called Kinatrax. If you had asked me before I read the article what “Kinatrax” was I would’ve guessed that it was some 1970s premium movie channel that didn’t survive HBO’s rise to prominence. But it’s somehow even cooler than that:

Kinatrax uses ultra-high-speed cameras and aims to capture the sort of biomechanical data that previously necessitated the placement of reflective markers on different body parts. Should Kinatrax do what it purports to, it would revolutionize baseball by offering looks at pitchers’ in-game biomechanics instead of those revealed in laboratory settings.

Passan’s article talks about potential applications and the practical use of the system (i.e. it’s TREMENDOUSLY data-intensive). But even if it’s a new thing that will eventually be streamlined into something better, it’s a neat start.

Houston’s Yordan Alvarez leaves game with ankle discomfort

Thomas Shea-USA TODAY Sports

HOUSTON — Houston slugger Yordan Alvarez left the Astros’ game against the Arizona Diamondbacks in the fifth inning with left ankle discomfort.

Alvarez, who is tied for second in the American League with 37 home runs, rolled his ankle running out of the box on a single in the first inning.

He looked to be in some pain as he jogged to first base and was checked on briefly by manager Dusty Baker and a trainer before remaining in the game. Serving as the designated hitter, he struck out in the third inning before being replaced by pinch-hitter David Hensley for his at-bat in the fifth.
