The Arizona Diamondbacks are close to promoting top prospect Kevin Cron.
According to a source, Cron will be added to Arizona's roster for this weekend's series against the San Francisco Giants.
The 26-year-old is the younger brother of Minnesota Twins slugger C.J. Cron. He leads the Minor Leagues with 21 home runs and 62 RBIs over 44 games with Triple-A Reno this season.
