The Diamondbacks announced this morning they’ve designated reliever Anthony Swarzak for assignment. Right-hander J.B. Bukauskas has been recalled from the alternate training site, while outfielder Tim Locastro was placed on the 10-day injured list.
Selected to the D-Backs’ roster a week and a half ago, Swarzak went on to log 4.2 relief innings across six appearances for Arizona. The veteran righty allowed five runs on seven hits, struck out four and issued a walk. That marked his first MLB action since 2019, when he pitched to a 4.56 ERA/4.65 SIERA over 53.1 frames.
He’ll be replaced on the active roster by Bukauskas, a former first-round pick now slated to make his major league debut. The 24-year-old was drafted fifteenth overall by the Astros in 2017 coming out of the University of North Carolina. He wound up dealt to Arizona as part of the four-player return for Zack Greinke at the 2019 trade deadline. Baseball America placed Bukauskas 26th in the Arizona system entering the year, lauding his three-pitch mix but noting that he’s often plagued by below-average control.
Locastro dislocated his finger attempting to steal a base yesterday and was known to be headed to the injured list. The recently-acquired Nick Heath is getting the nod in center this afternoon against Nationals righty Paolo Espino.
