Former Yankees star Joba Chamberlain says his ex-team is going to have to cut a fat check to Aaron Judge to keep him around next season and longer ... telling TMZ Sports he believes they've "got to" give him $40 MILLION per year.
A contract of that magnitude would make the outfielder the second-highest paid player in baseball -- just $3 mil shy of Max Scherzer's annual $43 million payday -- but Joba says the Yanks just have to do it.
"Pay him, now. Immediately," Joba says.
