The Major League Baseball Umpires Association is not happy with San Diego Padres star Manny Machado's punishment for making contact with an umpire.

Machado was suspended one game after arguing a called third strike with plate umpire Bill Welke during Saturday's game against the Colorado Rockies

"One game..one single game. What kind of precedent is that setting? It is NOT okay to throw a temper tantrum and physically touch someone of authority, just because you don't agree. Violence in all workplaces is not tolerated. Period," the MLBUA said in a Facebook post on Tuesday.

MLB said the punishment, imposed by chief baseball officer Joe Torre, was for "aggressively arguing and making contact'' with Welke. Machado denies that he made contact with the umpire and said he's appealing the one-game suspension and fine.

"We have our case and we're going to wait to see what the appeal comes back with. We always have the right to argue balls and strikes and give our opinion on it," Machado said.

In their Facebook post Tuesday, the MLBUA called the one-game suspension a "slap in the face" and said any physical contact with an umpire cannot be tolerated.

"Major League Baseball has to always lead by example in all cases of violent behavior, on and off the field. With that being said, the MLBUA is extraordinarily disappointed in Major League Baseball for its disciplinary 'inaction' handed down to Manny Machado."

The 26-year-old Machado is batting .261 with 13 home runs and 39 RBIs for the Padres after signing a $300 million, 10-year contract in spring training.
