"I try to get a good dig in on somebody once a week, maybe once every two weeks," Berkman said. "I don't bring it up unless things are going good and we've been in a little lull lately."
He doesn't have to worry about the Rangers digging him back in return.
"What are they going to give back?" Berkman said. "The guy who is scary is Adrian Beltre. He's not amused by any of that."
Berkman is back in St. Louis but is not expected to start in any of the three games. There is no designated hitter in the National League city, and the Rangers activated first baseman Mitch Moreland off the disabled list on Friday, and he was immediately back in the lineup.
