The Diamondbacks have made a trade for JB Bukauskas, a right-handed pitcher who was once among the top 100 prospects. The right-hander was selected by Houston with the 15th overall pick in the 2017 draft. The Diamondbacks acquired him as part of the deal for Zack Greinke, and he’s since struggled to sustain his success. He has not started a game at the major or minor league level since April 19, while playing with the Diamondbacks’ Double-A affiliate.
