Righty Alec Mills (low back strain) made his first rehab appearance Saturday at Triple-A Iowa, throwing three innings and allowing three earned runs. Mills, who was back at Wrigley Field on Sunday, called the outing a “step in the right direction.” Importantly, he said he got through the appearance without feeling anything.
Mills is expected to make another rehab start later this week, but he didn’t want to put an exact timetable on his return to the Cubs.
