Starting pitcher Matt Garza was put on the 15-day disabled list by the Milwaukee Brewers because of a strained muscle in his back. The move is retroactive to Saturday.
Right-hander Tyler Cravy was recalled from triple-A Colorado Springs on Tuesday to replace Garza.
Garza departed an exhibition game start Friday in the fourth inning with what was then described as right shoulder tightness.
The veteran right-hander was looking to rebound from his worst season since his rookie year with Minnesota in 2006. He was 6-14 with a 5.63 earned-run average in 25 starts last season.
Garza was 1-0 with a 4.50 ERA in six starts in spring training.
Commissioner to rule on Jose Reyes case soon
Commissioner Rob Manfred said he expects to rule soon on possible discipline for Colorado Rockies shortstop Jose Reyes.
Reyes was scheduled to go to trial April 4 after pleading not guilty to abusing a family or household member, a charge that stemmed from an Oct. 31 incident with his wife at a Maui resort hotel.
Reyes was suspended with pay under baseball's new domestic-abuse policy, an action Manfred took just before the shortstop was to report to spring training.
Hawaii prosecutors dropped charges last week and said Reyes' wife was not cooperating.
Wrigley Field's marquee to be reinstalled
The Chicago Cubs announced that Wrigley Field's iconic marquee is scheduled to be reinstalled Wednesday after an off-season restoration that included structural repairs and cosmetic work.
Restored statues of Ron Santo, Billy Williams and Harry Caray were installed Monday outside the ballpark. The Ernie Banks statue is scheduled to be reinstalled Friday.
The work is part of an ongoing multiyear transformation of the ballpark and surroundings that includes a new home clubhouse this season.

MLB approves use of wearable technology
Major League Baseball's playing rules committee approved two wearable technology devices for use during games this season, two people familiar with the decision told the Associated Press. The Motus Baseball Sleeve measures stress on elbows and the Zephyr Bioharness monitors heart and breathing rates.
In addition, the committee approved two sensors for use during workouts, one from Blast Motion and the other from Diamond Kinetics.
People spoke about the decision on condition of anonymity because no announcements were authorized by MLB or the players' association.
