Marc Topkin’s takeaways from Rays’ 4-2 Sunday win over White Sox:* Travis d’Arnaud hasn’t only been a hit at the plate. His work behind the plate, in blocking pitches and in calling a game, has been impressive, earning the praise and trust of Blake Snell and others. A guy the Mets discarded has been a huge pickup for the Rays, who are a better team. * Sometimes a team just has to find a way to stop the downward spiral and win a game, somehow, some way. The Rays were in that position Sunday, having dropped five straight and looking bad in doing so, and with the chance for worse, with six of their next nine games against the Red Sox. * Matt Duffy may have to wait a day to be activated, and will have to fight the natural urge to try to do too much in his season debut. But he will be a welcome addition to a lineup that needs his style of grinding out at-bats and his experience in slowing the game down and avoiding quick innings.
