De La Rosa (shoulder) will pitch one inning in a rehab game Saturday with the Diamondbacks' rookie-level club, the Associated Press reports.
De La Rosa hit the 10-day disabled list shortly before the All-Star break with right shoulder inflammation, but it doesn't seem to be a serious concern. While it's possible De La Rosa will require another rehab outing or two beyond Saturday, it shouldn't be long before he rejoins the big club.
