Leone (biceps) will start a throwing program Monday, Jenifer Langosch of MLB.com reports.
Leone recently began a strengthening program for his arm and will now progress to a throwing regimen. A return date remains unclear, as he's been on the shelf for over four weeks, but it seem unlikely that he will return before the All-Star break, especially considering the nerve issues he's been experiencing. Look for an update on his status once he resumes throwing.
