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?

Tomorrow will mark a week since the Red Sox reportedly inked outfielder J.D. Martinez to a five-year, $110 million contract. The signing hasn’t been made official yet, however, due to an apparent medical issue. That will change tomorrow morning as the Red Sox have a press conference scheduled with Martinez where they’re expected to announce the signing at long last, Evan Drellich of NBC Sports Boston reports.

According to Jon Heyman of FanRag Sports, the terms of the deal aren’t expected to change. Presumably, the Red Sox had some safeguards put into the contract to protect them against whatever spooked them with the results of Martinez’s physical.

Martinez, 30, was the top free agent hitter after batting .303/.376/.690 with 45 home runs and 104 RBI in 489 plate appearances last season with the Tigers and Diamondbacks. He has expressed an interest in continuing to play in the outfield, but MLB.com’s Ian Browne says he will get a majority of his playing time as a DH with the Red Sox. Hanley Ramirez will share first base with Mitch Moreland.
