Rehab city

Left-hander Franklin Morales, coming back from a throwing shoulder strain, had as good a first rehab assignment as the Rockies could have expected on Sunday.

Morales went four innings and gave up two runs on five hits, and threw strikes on 48 of his 72 pitches.

“I talked to a lot of people, and he had a tough first inning and got better after that,” Rockies general manager Dan O’Dowd said. “He threw 86-94 mph, averaged 91-92. He showed good arm strength, his delivery was better. He’s still a work in progress, but it’s a good first step.”

Rockies manager Jim Tracy said Morales will receive another start, then the Rockies will evaluate him.

Right-hander Matt Daley (sprained left foot) is scheduled to throw an innning in Colorado Springs on Monday night, but rain is threatening that. Tracy said his rehab should be a short one.Catcher Chris Iannetta (strained right hamstrings) is due to join the Colorado Springs club on Tuesday. Tracy said there is a chance Iannetta will rejoin the club in Milwaukee at the end of the current road trip.

Now, for the guys who are here at Minute Maid Park for a three-game series with the Astros. …

Center fielder Dexter Fowler receives a rest, and Ryan Spilborghs leads off and plays center.
