The Pirates are monitoring players’ vital signs during games

And calorie consumption and stuff like that. All via some cutting edge athletic technology. Or at least cutting edge for baseball. From Travis Sawchik of the Pittsburgh Tribune:

Prior to and during games this exhibition season, some Pirates are wearing Zephyr workload monitoring devices. Under select players’ jerseys is a tight-fitting, compression shirt, which has a black, circular, detachable electronic device — about the size of a quarter — attached near the center of the chest. The device collects data from a sensor that records players’ heartbeats and energy consumption. The device’s most noticeable features are blinking green and red lights.

Russell Martin talks about how he has used it to monitor how many calories he burns during games. It also measures heart rate. Neal Huntington speculates that there are other things it could tell the Pirates if they decide to go wider-scale with their use. For now it’s just an experiment.

I wonder if it could potentially measure telltale signs of fatigue. That could be pretty useful for pitchers, couldn’t it?

Cardinals starter Michael Wacha suffered a strained left oblique muscle during his start this afternoon against the Phillies, causing him to leave in the fourth inning.

Wacha is 8-2 with a 3.20 ERA and a 71/36 K/BB ratio in 84.1 innings across 15 starts this season with St. Louis. To the extent he has to miss some time — and obliques invariably send starters to the disabled list — potential fill-in candidates include John Gant, Daniel Poncedeleon and Dakota Hudson.
