Before Francisco Rodriguez battled Alex Rodriguez in Sunday night's Subway Series finale, K-Rod had an altercation with bullpen coach Randy Niemann.

According to a story by Newsday's Dave Lennon:

The Mets led 6-2 at the time and K-Rod apparently got upset that Jerry Manuel had called to get him up the day after he threw 28 pitches in a five-out save in the previous night's 5-3 victory over the Yankees.

Rodriguez argued with Niemann, and a person familiar with the situation said the other relievers stepped in to separate the two, which caused a minor scuffle in the bullpen. K-Rod later told The New York Times that the group was only joking, but another person said Rodriguez's anger was real.

Lennon also writes that K-Rod was still upset over Manuel's decision to use him in a game last Thursday in Washington. The Mets almost blew a 9-1 lead before winning 10-7. After John Maine had only thrown five pitches and left the game, Manuel went through his bullpen and needed to use K-Rod with the Mets leading 10-6. It was a non-save situation for K-Rod.
