Rockies place Chatwood on DL

MIAMI -- The Rockies placed right-hander Tyler Chatwood on the 15-day disabled list with a mid-back strain and recalled righty reliever Scott Oberg from Triple-A Albuquerque on Sunday.

Chatwood left Saturday's 9-6 loss to the Marlins after 1 2/3 innings with spasms. Manager Walt Weiss said he hopes Chatwood's back heals soon so the team can rebuild his pitch count and return him to the rotation.

"I don't think it'll be much longer than [15 days], but it's hard to tell," Weiss said. "We're thinking at this point that will be sufficient, the 15 days. But with a pitcher you've got to build them back up a little bit. That'll be part of the process with Chatty."

Oberg was with the Rockies from April 25-May 20, posting a 4.76 ERA with six strikeouts and five walks in eight Major League outings spanning 11 1/3 innings. At Albuquerque, Oberg had a 2.89 ERA with 21 strikeouts against seven walks with five saves in six chances.

In Sunday's 3-0 loss, Oberg threw two scoreless innings, allowing two hits and striking out two.

The move might not be the end of the maneuvering. Righty Eddie Butler, who struggled after replacing Chatwood on Saturday, is in line to return to the rotation for the next turn. But the Rockies are left without a long reliever. Righty Jordan Lyles joined the Rockies on Sunday in Miami, but no roster move was announced.
