D'Arnaud, who is on the disabled list with a rotator cuff strain in his throwing shoulder, could begin a rehab assignment this weekend. He returned to Florida last week after spending time at home in California working with his own physical therapist/trainer.
Once d'Arnaud returns, it seems logical that Kevin Plawecki -- at least for the short term – will end up at Triple-A Las Vegas. Plawecki is hitting .196/.295/.272 in 105 plate appearances this season.
Meanwhile, veteran catcher Rene Rivera has received positive reviews, despite hitting .148/.281/.259. Rivera caught Monday's shutout against the Chicago White Sox, which included seven scoreless innings from Matt Harvey. Rivera also has thrown out three of eight would-be base stealers.
