1:35 PM PT -- Mets manager Carlos Mendoza addressed the decision to designate Lopez for assignment ... saying the team has standards and his actions would not be tolerated.

9:48 AM PT -- Lopez is clearing the air on his comments ... saying he was really calling himself out, not his teammates.

"Who ever hear me I said teammate and what I said on the situation I been the worst teammate thanks media for make it worse," he wrote on Instagram.

A bad outing for Mets reliever Jorge Lopez got worse and worse as the night went on ... 'cause not only did he throw his glove into the stands after getting ejected, he also unloaded on his team in a post-game interview -- and now, he's losing his spot on the roster.

The whole meltdown started shortly after Lopez gave up a two-run home run to Dodgers superstar Shohei Ohtani amid the Mets' late-game collapse ... when he started arguing over a checked swing call during the next at-bat.

Lopez got in a heated argument with the third-base ump over the ruling ... which resulted in him getting booted from the contest.

As he left the field, he threw his mitt into the crowd in frustration ... and when reporters asked him about his actions in the locker room, he said he didn't regret it one bit -- and he proceeded to call the Mets "the worst team in probably the whole f***ing MLB."

There was some speculation Lopez's comments were misunderstood ... but he later doubled down and said that's what he meant.

Following the game, the Mets elected to designate Lopez for assignment ... meaning he'll be either traded, released or booted to the minors.

The Mets ended up losing the game 10-3 ... falling to 22-33 on the season.
