Mills will start Friday in place of Cole Hamels, who was scratched with shoulder fatigue, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Mills has worked solely out of the bullpen since being recalled by the Cubs on Sept. 1, but he will get a chance to start Friday with Hamels unable to go. Mills has thrown the ball well this month, allowing just one earned run over six innings (1.50 ERA) while giving up just four hits and posting a 9:0 K:BB, but he has not thrown more than 40 pitches in any outing, so it remains to be seen how deep he will be able to go in Friday's contest.

Mills (1-0) picked up the win Monday against the Reds, tossing two scoreless innings in relief. He allowed one hit and struck out three.

EDGE Analysis

Mills has given the Cubs some valuable innings lately and picked up a few milestones to boot, as he earned his first MLB save by covering three innings Friday. He followed that up by recording his first MLB win with his two scoreless innings Monday. With Chicago pushing for a playoff spot, Mills has been a solid contributor in September with just one earned run allowed across six innings to go with nine strikeouts.

Mills recorded the save in Friday's 18-7 win over the Pirates, tossing three innings of one-run ball. He allowed two hits while striking out four.

EDGE Analysis

Mills had a comfortable lead to work with, but he looked sharp nonetheless and he efficiently worked through his three innings on 40 pitches (29 strikes), picking up his first MLB save and saving some other Chicago relievers from working in the process. The 27-year-old righty, who has been up and down from the minors this season, has a 3.70 ERA and 24 strikeouts in 24.1 innings at the MLB level this year.

Mills was recalled from Triple-A Iowa on Sunday.

EDGE Analysis

Mills will join the Cubs as part of the September roster expansion. The 27-year-old performed well during his brief time in the majors this season with a 3.98 ERA, 1.33 WHIP and 18:7 K:BB over 20.1 innings.

Mills was optioned to Triple-A Iowa on Thursday, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Mills tossed a quality outing in relief of Cole Hamels on Wednesday, allowing three runs on four hits (two home runs) and two walks while striking out four across six innings. He now owns a 3.98 ERA, 1.33 WHIP and 18:6 K:BB through 20.1 big-league innings this season. The Cubs will swap him out for a fresh bullpen arm in James Norwood.

Mills was recalled from Triple-A Iowa prior to Friday's game against the Reds, Jesse Rogers of ESPN.com reports.

EDGE Analysis

Kyle Ryan was placed on the bereavement list so the Cubs added a fresh arm to the bullpen. Mills has given up five runs in 10.1 innings this year and will offer some length in case any of the Cubs' starters get hit around early this weekend.

Mills was optioned to Triple-A Iowa on Tuesday, Mark Gonzales of the Chicago Tribune reports.

EDGE Analysis

Mills surrendered two runs on seven hits and a walk while striking out five Monday night in the series opener, but he'll be sent down in order to get a fresh arm in Chicago's bullpen. Tim Collins was brought up to the big club in a corresponding move.

Mills didn't factor into the decision against the Giants on Monday, giving up two earned runs on seven hits over 4.1 innings, striking out five and walking one as the Cubs eventually fell 5-4.

EDGE Analysis

Mills hurled a quality start in his first outing of the season against the Reds, but didn't fare quite as well this time, as he found himself unable to make it out of the fifth inning before departing the contest after tossing 76 pitches. Still, the 27-year-old has held his own over his two outings, so he could see at least one more turn in the rotation, as the Cubs still need an extra arm with Cole Hamels (oblique) on the injured list.

Mills will start Monday on the road against the Giants, Jordan Bastian of MLB.com reports.

EDGE Analysis

With Cole Hamels (oblique) only throwing bullpen sessions in his recovery process, Mills will retain his spot in the starting rotation for at least one more start. In the right-hander's first major-league start of 2019 against the Reds, he allowed three runs off five hits and one walk while recording six strikeouts in six innings. The Cubs considered going with a four-man rotation given their pattern of off days in the near future, but ultimately decided they had enough confidence in Mills to give him at least one more start, according to Tony Andracki of NBC Sports Chicago.

Mills didn't factor into the decision in Tuesday's 4-3 extra-inning win over the Reds, giving up three runs on five hits and a walk over six innings while striking out six.

EDGE Analysis

Cincinnati jumped on him for three runs in the first inning, but Mills settled down after that and came through with the first quality start of his brief big-league career. The right-hander may have earned a longer stay in the rotation with the performance, as Cole Hamels (oblique) still has no timetable for his return.
