The Cardinals are still trying to trade Nolan Arenado, who made it abundantly clear during the offseason that if he was going to be traded, he'd prefer to be traded to his hometown Dodgers. The list of teams he'd waive his no-trade clause for is more or less the same now as it was in the offseason (though it does curiously now include the Astros, who he blocked a trade to previously), and no doubt the Dodgers are still at the top of his list.
According to Fabian Ardaya and Katie Woo of the Athletic, the Dodgers are indeed eyeing a Cardinals infielder, but it's not Arenado.
