Kaprielian will start a throwing program in August, Susan Slusser of the San Francisco Chronicle reports.
Kaprielian remains on track in his recovery from the Tommy John surgery he underwent in April. The A's are likely to be cautious with their new prospect's recovery, with general manager Billy Beane suggesting that the 23-year-old right-hander isn't expected to return to minor-league action until next May at the earliest, according to Joe Stiglich of NBC Sports California.
