In the bottom of the inning, Castillo lined a drive deep to center field with one out and Castro on second. But the Rockies' Charlie Blackmon raced back and made a spectacular diving catch.
Rockies: In addition to Morneau, the Rockies activated left-handed reliever Boone Logan from the DL (diverticulitis/intestinal inflammation). Logan pitched a scoreless ninth. The Rockies also recalled infielder Cristhian Adames from Triple-A Colorado Springs before the game because infielder Josh Rutledge has an upper-respiratory infection.
Cubs: The Cubs placed right-handed reliever Neil Ramirez on the 15-day disabled list with a sore triceps.
Colorado left-hander Brett Anderson (1-3, 3.24 ERA) faces Chicago left-hander Travis Wood (7-9, 5.06 ERA) on Wednesday night. Anderson allowed no runs and two hits in 6 1-3 innings last Friday to earn his first win with Colorado. Wood is 1-1 with a 1.80 ERA in four career games against the Rockies.
Morneau went 2 for 4 in a rehab game at Triple-A Colorado Springs on Monday, but really felt ready to return when an MRI of his neck showed no serious damage, such as nerve impingement. ''Hopefully it's good to for the rest of the year,'' he said.
Logan said the pain from his diverticulitis was debilitating and affected his pitching shoulder. ''My (left) collarbone was killing me,'' he said. ''It was like it was broke in half because of the pain shooting.''
Are the Cubs potential sellers as Thursday's trade deadline nears? ''I expect to be active, we're having a lot of conversations,'' GM Jed Hoyer said. ''It's still early, but tomorrow is sort of moving day.''
