MLB: Cubs’ Zobrist has shoe support from teammates

Ben Zobrist was joined by Chicago Cubs teammates Kyle Schwarber and Steve Cishek in wearing black spikes Monday despite a warning from Major League Baseball that he was in violation of the sport’s uniform regulations.

Zobrist on Saturday posted a letter on Instagram from MLB that cited him for violating regulations requiring at least 51% of the exterior of a player’s shoes be the club’s designated primary shoe color. For the Cubs, that’s blue.

The letter said Zobrist will be subject to discipline, including a fine, if he continued to wear noncompliant shoes.

Zobrist wrote he has worn black cleats for day games at Wrigley Field the last two years to honor the game’s past.
