"I'm told he was not at the park," Puig's agent, Adam Katz, said. "The club informed me, and the player understood clearly that they were making every effort to trade him and that if they were unable to come to terms with another club on a trade — and successful in acquiring another outfielder — that he likely would be demoted. My understanding is that transaction will happen tomorrow."
Dodgers manager Dave Roberts said Puig's absence was a matter of him following instructions.
"[Puig] did what the organization asked him to do," Roberts told The Associated Press. "We didn't want him to come to the ballpark because we knew he wasn't going to Denver with us. We were looking for more production from that position, so we acquired a player [Reddick] who is having a really good year and great track record."
Dodgers general manager Farhan Zaidi, addressing the media about the team's trade-deadline moves, repeatedly declined to comment on any questions related to Puig.
Yasiel Puig hasn't been great for the Dodgers this season, but he's hardly been dull. Fittingly, his demotion to Triple-A brought attention, too.
