MIAMI (AP) Miami Marlins left-hander Mike Dunn has been placed on the 15-day disabled list because of a strained left forearm.

The move Sunday was retroactive to March 25. Dunn underwent an MRI which was negative, and the Marlins don't believe his injury is serious, president of baseball operations Michael Hill said Sunday.

Miami designated left-hander Brad Hand and outfielder Cole Gillespie for assignment. If Hand is not claimed, the Marlins could outright him to Triple-A New Orleans.
