Diamondbacks' Kevin Cron: Optioned to alternate camp

Cron was optioned to the Diamondbacks' alternate training site Thursday.

Cron made just one start over Arizona's first six games this season and went 0-for-4 with a walk and two strikeouts. He'll get the chance to continue developing at the alternate training site after catcher Daulton Varsho was added to the 30-man roster Thursday.
