The Arizona Diamondbacks officially moved All-Star center fielder A.J. Pollock to the extended disabled list and made a pair of pitching moves Tuesday.
Pollock, who suffered a fractured elbow in the D-backs' exhibition game Friday, was placed on the 60-day DL, the D-backs announced.
Pollock was scheduled to have surgery on his elbow Tuesday afternoon. There is no timetable for his return.
Also on Tuesday, the D-backs announced that relief pitcher Silvino Bracho has been optioned to Triple-A Reno. The 23-year-old right-hander allowed one earned run on two hits and a walk in 1 1/3 innings pitched in Monday's loss to the Rockies.
In Bracho's place, the D-backs called up right-hander Kyle Drabek. The 28-year-old has played in portions of six MLB seasons, and he spent 2015 in the Chicago White Sox organization.
Drabek, the son of 1990 National League Cy Young winner Doug Drabek, posted a 3.47 ERA in 24 appearances for Triple-A Charlotte last season. He signed a minor league contract with the Diamondbacks in November.
