I saw Dietz pitch today and it was as bad as the numbers indicate. Warming up in the bullpen he airmailed the catcher several times, causing the ball to ricochet off the outfield wall and onto the field of play. It was Nook Laloosh-esque but with poor stuff. The velocity was non-existent. He sat 92-93 and t94 (both on the stadium gun and multiple scouts' guns, so it's accurate). He occasionally mixed in a fluttering 84-85 breaking pitch that I think was supposed to be a slider, but it didn't really move and was up in the zone every time he threw it. Obviously, control/command was awful.
He needs to go down to extended spring for a complete overhaul, they need to get him out of A+ ball. It was difficult to watch.
