Rudy Giuliani just went scorched earth on the MLB ... calling the league's anthem kneelers "hyopcritical" -- and saying the Black Lives Matter supporters in baseball are "disgraceful."
The former New York City mayor and diehard Yankees fan ripped the league Friday morning ... just hours after several players -- including Dodgers star Mookie Betts -- knelt for not only the national anthem, but in support of BLM as well.
"All those ball players, including the Yankees, taking a knee during the National Anthem of the country that made them millionaires is hypocritical," Donald Trump's attorney said.
