Breed did not call specifically for Major League Baseball to suspend Baer, saying there "needs to be consequences, what those consequences are need to be determined."

"I am truly sorry for the pain that I have brought to my wife, children and to the organization," Baer said. "It is not reflective of the kind of a person that I aspire to be, but it happened and I will do whatever it takes to make sure that I never behave in such an inappropriate manner again."
The Giants announced March 4 that Baer would take an indefinite leave of absence.
