As we previously reported, 54-year-old Becker -- a 6-time Grand Slam winner -- was convicted by a jury earlier this month on multiple charges under the Insolvency Act in Britain ... including charges he concealed assets and debts.

Becker was also found guilty of transferring hundreds of thousands of dollars (well, pounds) from his business account to other accounts after declaring bankruptcy in 2017.

The judge who handed down the sentence said the former #1 ranked tennis player will have to serve half of his sentence, according to CNN.

And, it could've been much worse for Becker ... who was facing up to 7 years behind bars after his conviction.

The judge didn't spare the 3-time Wimbledon champ from taking a verbal beating during sentencing ...  the judge ripped into Boris as a remorseless criminal.

"I take into account what has been described as your fall from grace. You have lost your career and reputation and all of your property as a result of your bankruptcy," the judge said, according to the Press Association.

"You have not shown remorse, acceptance of your guilt and have sought to distance yourself from your offending and your bankruptcy."

The judge continued ... "While I accept your humiliation as part of the proceedings, there has been no humility."

As for Becker ... he seemed somewhat remorseful at times, even saying during his trial that he was embarrassed over the bankruptcy scandal, and even offered to part ways with his wedding ring to help satisfy his debts.
