The Miami Marlins placed outfielder Austin Kearns on the 15-day disabled list Thursday with a right hamstring strain.
Kearns was hurt Tuesday night, and hadn't progressed enough by Thursday. He was batting .375 with three homers in 48 at-bats this season.
The team recalled outfielder Kevin Mattison from Triple-A New Orleans to take Kearns' spot. Mattison spent a few days with the team earlier this month, but had one at-bat.
