The penalty was announced by MLB senior vice president for on-field operations Michael Hill.
Suárez appealed the discipline to John McHale Jr., a special assistant to baseball commissioner Rob Manfred. Any suspension will be delayed while the appeal is pending.
Suárez was ejected Wednesday for having sticky stuff on his left wrist and arm before he threw a pitch in the eighth inning against Miami. Suárez denied using any banned substances, saying he had sunscreen on his arm because it was a day game.
"We were doing a routine check," crew chief Todd Tichenor said. "We deemed it was too sticky, very sticky, and he was ejected from the game."
