PHILADELPHIA — Silence hung over Citizens Bank Park around 3:30 p.m. Wednesday, three hours before the Philadelphia Phillies’ new defensive arrangement took the field a second time.The scoreboard wasn’t on. The music did not play. The only disruption, albeit small, was when Luis Arraez, the new second baseman, climbed the dugout steps alongside infield coach Bobby Dickerson. Arraez knelt in the wet grass next to the tarp. Dickerson tossed and then hit to him as Arraez alternated fielding with a pancake mitt and his typical glove.So much was different: the lack of noise in a place typically full of it, the second baseman in his second day on the job, the positions he and his teammates would play later that night. Yet, three games into the Phillies’ defensive shuffle, things have mostly felt normal.“Is there going to be maybe a little bit of a learning curve? Sure,” Trea Turner said Thursday, “but I just feel like the routine plays will be good. … So, it’s really just me picking up my side. I feel like the last three days have been really good. I can’t remember, like, a play we haven’t made. We turned some double plays. (Bryson) Stott made some good plays.“Maybe it’s not as big (an adjustment) as everyone seems (to think), but I think there’ll still be some hiccups along the way. I think we’re ready for that. Like, we know that. But so far so good.”Who won and lost the MLB trade deadline?Andy McCullough and Johnny SweetNo roadblocks have arrived yet. Everything looked fine for the Phillies in a 7-3 win against the Washington Nationals on Thursday, and there have been few miscues in the three games. The Phillies have made some of the most drastic changes of any team after the trade deadline, with three position changes and a fourth position player (Arraez) joining the roster, yet the early returns haven’t been especially noteworthy — a positive in itself.There are, of course, the expected changes associated with all of this: interim manager Don Mattingly talking with Alec Bohm during defensive drills, Bryce Harper bowing to the right-field stands once more, players standing in different places. All of this has trickled down in various ways.
