Mills (back) will make another rehab start at Triple-A Iowa on Tuesday, Maddie Lee of the Chicago Sun-Times reports.

EDGE Analysis

Mills has made three rehab starts during his current stint with the Triple-A club, and he's posted a 3.72 ERA and 1.24 WHIP in 9.2 innings. The right-hander is eligible to return from the 60-day injured list as early as Monday, but he'll have at least one more opportunity for a tune-up in the minors prior to rejoining the Cubs. Assuming he feels good following Tuesday's outing, it's possible that he'll be reinstated from the injured list as early as next weekend.

Mills (back) will throw a three-inning rehab start Friday, Maddie Lee of the Chicago Sun-Times reports.

EDGE Analysis

He is expected to throw 55 pitches in this outing after throwing 43 pitches in 2.1 innings in his prior rehab start. Given that Mills is ineligible to be activated from the 60-day injured list until June 8, it seems likely that he will make at least one more rehab start after Friday's scheduled outing.

Mills (back) began a rehab assignment at Triple-A Iowa on Sunday and tossed 2.1 innings in his start against Columbus. He worked 2.1 innings and gave up one run on two hits and a walk while striking out two in Iowa's 5-2 loss.

EDGE Analysis

Mills pitched in a game for the first time since April 23, when he experienced quad tightness that resulted in him being pulled off his initial rehab assignment at Iowa for the ensuing month. He tossed 43 pitches (25 strikes) on Sunday, but he'll still likely need at least two more rehab start before the Cubs entertain bringing him back from the 60-day injured list. Before he was placed on the IL shortly before Opening Day, Mills looked to be in good position to claim a rotation spot for the Cubs, but he might have to settle for a long-relief role once he's formally activated.

Mills (back) was transferred to the 60-day injured list Thursday, Tim Stebbins of NBC Sports Chicago reports.

EDGE Analysis

Mills was cleared to face hitters this weekend and threw a bullpen session Thursday, but he'll now be moved to the 60-man injured list to make room on the 40-man roster. The right-hander will likely require several rehab games before rejoining the Cardinals, so Thursday's transaction is unlikely to alter his recovery timetable.

Mills (back/quadriceps) is scheduled to throw live batting practice Sunday, Maddie Lee of the Chicago Sun-Times reports.

EDGE Analysis

The right-hander has been throwing bullpen sessions for the past week and will now progress to facing live batters. Mills has yet to see MLB action this season due to the back and quadriceps injuries, so he figures to require a multi-game rehab stint in the minors before joining the Cubs.

Mills (back/quadriceps) will throw a couple more bullpen sessions before beginning a rehab assignment, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

The right-hander began a rehab assignment in late April before experiencing quadriceps tightness, but he recently resumed mound work and is again progressing toward his return. Mills figures to require a multi-game stint in the minors to continue building up his workload once he's cleared for game action.

Mills (back/quadriceps) will throw off a mound within the next few days before being re-evaluated, Jordan Bastian of MLB.com reports.

EDGE Analysis

It's been a slow ramp up for Mills, as he recently resumed playing catch after suffering a setback with his quad while he was making rehab starts in an effort to return from a back injury. He could resume a rehab assignment in the coming weeks if all goes well.

Mills (back/quadriceps) has resumed playing catch, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

Mills sustained a setback in his recovery last week due to right quadriceps tightness, but he's now resumed a throwing program. However, it's not yet clear when he'll be able to return to the minors to continue his rehab assignment. The right-hander will likely need to complete at least one bullpen session before he's cleared for game action.

Mills (back) isn't scheduled to make his second minor-league rehab start this week after he experienced right quadriceps tightness during a workout Tuesday, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

Mills, who opened the season on the 10-day injured list with a lower-back strain, made his first rehab start at Triple-A Iowa on Saturday, striking out five over three innings while allowing three earned runs on eight hits and no walks. He was expected to take the hill again for Iowa this week, but the quad issue will result in him being shut down for at least the next couple of days. The Cubs may want to see Mills make it through a bullpen session without discomfort before adding him back to the minor-league pitching schedule.

Mills (back) will make a rehab start at Triple-A Iowa on Friday, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

Mills faced hitters in a live BP session Tuesday, and he'll return to game action in a minor-league setting Sunday. The right-hander threw 77 pitches in a simulated game last weekend, so it seems likely that he'll be able to rejoin the Cubs' rotation following a relatively brief rehab assignment.
