Heaney (elbow) will make a rehab start at Triple-A Salt Lake on Monday, Pedro Moura of The Los Angeles Times reports.
After undergoing Tommy John surgery a year ago, Heaney continues to make progress during his rehab, working his way up from the AZL Rookie League team to Triple-A Salt Lake within the past few weeks. During three appearance in Rookie ball, Heaney allowed just two earned runs while striking out 15 in nine innings of action. The left-hander is expected to throw five or six innings during Monday's outing, and could wind up making a couple more starts at the Triple-A level while building his arm back up to its past form.
