Cuddyer heading to Arizona for rehab stint

Rockies outfielder fine after running bases; Rosario nearing return

KANSAS CITY -- Rockies outfielder Michael Cuddyer, recovering from a left hamstring strain, ran the bases on Tuesday with no ill effects. That session provided the green light for Cuddyer to schedule a Wednesday flight to Arizona for a rehab assignment.

Cuddyer is scheduled to play in some extended spring games starting on Thursday.

"Hopefully, I'll be back for the Giants series [beginning May 20]," Cuddyer said. "You've got to play some games to make sure you are at game speed."

Cuddyer was hitting .317 through 16 games with three homers and 10 RBIs when he suffered the hamstring strain.

Rockies manager Walt Weiss said regular catcher Wilin Rosario, who has been on the disabled list because of a viral infection, is also progressing well.

"I think he and Cuddy both will be with us shortly," Weiss said. "Wilin is getting some at-bats down in Arizona. Within a week, we've got a chance of seeing both guys."

Morneau hopes to relive success against KC

KANSAS CITY -- Justin Morneau had many enjoyable days playing at Kauffman Stadium during his 11-year stint with the Minnesota Twins in the American League Central. In those 11 seasons, Morneau had 58 extra-base hits in 143 games against Kansas City (31 doubles, one triple, 26 home runs).

Now, Morneau is back in familiar territory for a two-game series against the Royals and swinging the type of hot bat that Kansas City fans remember from Morneau's AL days.

Morneau entered the two-game set with a .329 batting average, eight homers and 29 RBIs. Those numbers haven't surprised former Twins teammate Michael Cuddyer, who recommended that the Rockies sign Morneau. The early hitting surge by Morneau hasn't been Coors Field-inflated, as Morneau entered the Royals series with a .315 average, four homers and 13 RBIs on the road.

"This is what I envisioned for Justin," Cuddyer said. "He needed to get last year out of the way, as far as knowing he could play healthy again. That was the first obstacle. Now, he knows he's healthy and everything is fine, so it's just a matter of getting back to production."

Like Morneau, Cuddyer also has happy memories of Kauffman from Cuddyer's years with the Twins. But Cuddyer, who is on the disabled list, has to miss the Kauffman regular-season games this time around.

"One afternoon [Aug. 23, 2009], I hit two homers here in one inning and became the only Twin to do that," Cuddyer said. "That was pretty cool."

Rutledge activated from DL, sent to Triple-A

KANSAS CITY -- The Rockies took care of some roster housekeeping on Tuesday when they activated infielder Josh Rutledge from the 15-day disabled list and optioned him to Triple-A Colorado Springs.

Rutledge had been placed on the DL on May 2 because of a viral infection. He hit .318 in 11 games for Colorado with one homer and four RBIs.

"Rut is going to get his at-bats down in Triple-A," manager Walt Weiss said before Tuesday's series opener against the Royals.
