(AP Photo/Matt York)NEW YORK – Major League Baseball is increasing its monitoring of baseballs in an attempt to suppress any use of foreign substances by pitchers.
Ad—Gameday compliance monitors and electronics compliance officers will check for violations in dugouts, clubhouses, tunnels, batting cages and bullpens, and they will file daily reports to the commissioner’s office.
A third-party lab will be used for examinations, and suspicious balls will be traced back to pitchers.
—MLB Statcast data will be reviewed by the commissioner’s office to analyze spin rate changes among pitchers suspected of using foreign substances, comparing game data with career norms.
“As a reminder, all club personnel are prohibited from assisting players in the use of foreign substances and also will be subject to discipline by the commissioner, including fines and suspensions,” Hill wrote.
