[Burn City Sports] Who is the Diamondbacks’ Best Option to Start Sunday? - what will most likely happen with the Diamondbacks rotation is either Brandon Pfaadt gets moved to Sunday to accommodate adding Henry to the rotation, or Walston will make his first career start. He has one major league appearance, throwing 3 2/3 innings in relief on May 1 in his debut before getting sent down to Reno. If the Diamondbacks want to make the least intrusive move, while at the same time getting a better opportunity to evaluate the 22-year-old lefty, then turning to Walston makes the most sense.
