Dave Roberts is annoyed with suggestions by the New York Mets that the Los Angeles Dodgers have a "system" for knowing what pitches are coming.

On Wednesday, several Mets intimated that the Dodgers may have developed an advantage beyond the bounds of Major League rules.

"I guess if they feel ... the quality of at-bats we put up against these guys was not as a result of our talent and our preparation, then that's their decision," Roberts said. "I can't change their thoughts."
