San Diego Padres star Manny Machado was suspended one game by MLB for “aggressively arguing and making contact” with home plate umpire Bill Welke on Saturday.

As news of his suspension broke on Monday, it was also reported that Machado is appealing it, denying he contacted Welke at all.

On Tuesday, the MLB Umpires Association lashed out at Machado with a scathing statement over the incident.
