Morgan (knee) began a throwing progression this week, per MLB.com.
Morgan has been on the IL since late June due to soreness in his left knee. The righty reliever had been pitching pretty well prior to getting hurt, posting a 2.08 ERA and 1.27 WHIP with an 11:2 K:BB over 8.2 innings spanning seven appearances since the calendar flipped to June. Morgan isn't expected to return to San Diego by the All-Star break, but he could be activated before the end of July.
