Arizona designated Scott for assignment Saturday.
Scott had his contract selected from Triple-A Reno on June 10 and allowed nine runs on 13 hits with a 7:4 K:BB over nine innings spanning six appearances while with Arizona. Prior to that, he posted a 5.40 ERA across 16.2 frames as a member of the Astros. Scott's removal from the 40-man roster Saturday made room for the Diamondbacks to select the contract of fellow reliever John Curtiss from Reno.
