The Miami Marlins placed outfielder Austin Kearns on the 15-day disabled list with a right hamstring injury.
Kearns left Tuesday's game against the Rockies after his hamstring tightened while running the bases.
This season, Kearns is hitting .375 with 3 home runs and nine RBI in 22 games for the Marlins.
Outfielder Kevin Mattison takes Kearns' place on the roster. Mattison is hitting .252 with five home runs and 15 RBI with Triple-A New Orleans (PCL) this year. He is with the Marlins for the second time this season. In his first stint, he played only one game and did not reach base in his only at- bat.
