Report: K-Rod clashes with bullpen coach

Closer Francisco Rodriguez got into a heated argument with bullpen coach Randy Niemann over his usage on Sunday night against the Yankees, according to a report.

The New York Times reported K-Rod had to be separated from Niemann by other relievers.

Last week, John Maine and Jerry Manuel had a heated exchange in the dugout after Maine was pulled after five pitches in Washington.

And K-Rod and then-Mets VP Tony Bernazard had a verbal altercation upon boarding a team bus in Atlanta last season, weeks before Bernazard was fired.
