MLB bans 4 minor league pitchers for using foreign substances to doctor baseballs

Four minor league pitchers have been suspended this season by Major League Baseball after being caught using illegal foreign substances to doctor baseballs, signaling a stronger crackdown in the game's feeder system than in the big leagues during a historically dominant stretch by pitchers.

Chicago White Soxorganization right-hander Marcus Evey of Low-A Kannapolis received a 10-game ban from MLB after he was ejected from a May 13 game when umpires discovered a foreign substance.


Three more players were suspended 10 games after being busted last weekend -- Sal Biasi of High-A Winston Salem, also in the White Sox system; Kai-Wei Teng of High-A Eugene with the San Francisco Giants; and Mason Englert of Low-A Down East with the Texas Rangers.

The use of homebrewed tacky substances -- mixtures often involve sunscreen and rosin -- is suspected to have spiked in recent seasons as pitchers have learned the extent to which illicit sticky stuff can increase the spin rates on their fastballs, making the pitches more effective.

Many believe the proliferation of those grip aids is partially responsible for baseball's offensive free fall. There have been six no-hitters this season, one shy of the record since 1900, and the league's .236 batting average was the lowest through May 31 since 1968.

MLB has a regularly scheduled owners meeting Thursday, according to multiple reports, and the use of foreign substances is expected to be on the docket.

There has been increased oversight in the majors with efforts to inspect more baseballs this season, but the data collection has not led to penalties for players. Suspensions at the big league level are subject to bargaining with the players' association. Minor league players don't have a union.

Ace Trevor Bauer, now with the Los Angeles Dodgers, strongly and publicly urged MLB to take action concerning existing rules banning substances early in his career. He went mum on the subject last season, when his own spin rates spiked as he won the NL Cy Young Award with the Cincinnati Reds.


St. Louismanager Mike Shildt said last week that sticky substances used by pitchers are "baseball's dirty little secret" after Cardinals right-hander Giovanny Gallegos was ordered to switch hats when umpires identified a substance on the bill. Shildt believed Gallegos was being unfairly singled out for a widely committed offense.

"Did Gio have some sunscreen at some point in his career to make sure he doesn't get some kind of melanoma? Possibly," Shildt said. "Does he use rosin to help out? Possibly. Are these things that baseball really wants to crack down on? No."

MLB decided before this season to increase its monitoring of baseballs in an attempt to suppress use of foreign substances by pitchers.

A March memo from MLB executive vice president of baseball operations Mike Hill to teams laid out a three-point plan for cracking down that included game-day compliance officers to monitor areas near the field, a system for submitting baseballs that come out of play to the commissioner's office for inspection and a review of MLB Statcast data to analyze changes in spin rates among pitchers suspected of using foreign substances.

The oversight hasn't resulted in any known punishments.
