DETROIT -- The Astros shuffled All-Stars on and off the disabled list on Friday, activating left-handed ace Dallas Keuchel (neck discomfort) and righty reliever Will Harris (right shoulder inflammation), while placing outfielder George Springer on the 10-day DL with left quad discomfort.
Keuchel made his first start in nearly two months in the Astros' 6-5 series-opening win against the Tigers at Comerica Park on Friday, allowing three runs on six hits and three walks over three innings. Houston manager A.J. Hinch said he's going to try to ease Harris back into high-leverage relief spots.
Keuchel, whose last start was June 2, was 9-0 with a 1.67 ERA before being placed on the DL on June 8, retroactive to June 5. In the 44 games he missed while on his second neck-related DL stint this season, the Astros went 26-18. Keuchel also missed 10 days from May 17-27 with a pinched nerve in his neck.
Harris, a 2016 All-Star, hasn't pitched in the Majors since July 5, and he was 2-2 with a 2.86 ERA entering Friday. Harris tossed a perfect 15-pitch inning in his only rehab appearance for Class A Advanced Buies Creek on Wednesday.
As for Springer, who had his spike caught in the ground while fielding a ball off the wall Monday against the Phillies, there was previously hope from the team that he'd be ready to play in Detroit after Thursday's off-day.
"He was disappointed going on the DL," Hinch said of Springer, who spent just over two months on the DL in 2014 with a left quad strain. "He feels like he can play, he just can't play at his highest speed. So I think if we stay conservative with this and give him a couple days off and test him again midweek, then next Friday is the potential target date for us."
Springer, Houston's leadoff man and a 2017 All-Star, will be eligible to return on Aug. 4 against Toronto at Minute Maid Park because his time on the DL is retroactive to Tuesday.
"At this point in the year, it's a lot smarter to miss six games instead of six weeks," Springer said. "It'll be tough, but I'm just gonna have to get through it and get back to helping the team as soon as I can."
Worth noting
• For the time being, Brad Peacock is headed back to the Astros' bullpen. He's made 11 starts since May 22, compiling a 6-1 record with a 2.93 ERA in that span.
But Peacock didn't have to wait long to see meaningful action, filling in for Keuchel in the fourth inning on Friday after Keuchel ran his pitch count up to 79. Peacock allowed two runs on three hits over four innings and picked up his ninth win of the season.

• Struggling right-handed reliever Michael Feliz was also optioned to Double-A Corpus Christi on Friday to make room on the roster for Keuchel.
Feliz had a 9.39 ERA in 7 2/3 innings through eight appearances in July. In his most recent outing on Wednesday vs. the Phillies, he allowed six earned runs on eight hits while throwing 44 pitches, all season highs, in two innings. Hinch attributed usage and pitch location to Feliz's recent struggles.
"He's gotta figure out a breaking ball that works for him more consistently," Hinch said. "I think his fastball being up in the zone, he's gotta go higher than high if he's going to challenge guys up in the zone."
Fantasy spin | Fred Zinkie (@FredZinkieMLB)
Among the top fantasy assets at any position this season, Springer is going to leave a major hole in owners' lineups during his time on the disabled list. But on a positive note, the waiver wire is flush with appealing outfielders in most mixed leagues. Springer owners in shallow formats should check on the availability of hot-hitting Rockies outfielder Gerardo Parra or sluggers Josh Bell and Matt Adams. Meanwhile, those in deeper leagues can take a look at rookies Bradley Zimmer, Clint Frazier or Nick Williams.
