Alexander was optioned Friday to Triple-A Reno.
Alexander was one of seven players in this round of cuts from the major-league side of Diamondbacks camp. The 23-year-old infielder could climb to the majors at some point during the 2023 campaign after slashing .301/.389/.540 with 20 home runs and 10 stolen bases in 98 minor-league games last season. He finished up at Reno.
