On Thursday, outfielder Austin Kearns was placed on the 15-day disabled list with a right hamstring strain.
Outfielder Kevin Mattison was recalled from Triple-A New Orleans to fill Kearns' roster spot. It's Mattison's second stint with the club. He was first brought up on May 10, but sent down four days later after one big league at-bat.
Kearns has been a big contributor in limited playing time. He's batting .375 with three home runs and nine RBIs. He strained his hamstring while scoring from first base on Giancarlo Stanton's double in Tuesday's win over the Rockies.
Bryan Petersen, Chris Coghlan and Mattison are all left-handed-hitting outfielders on the roster.
"We have to have confidence in the guys we brought in," manager Ozzie Guillen said. "We've got Petey and Coghlan up here. Kearns is going to create a little hole against lefties."
Kearns was getting starts mostly against left-handed pitching. The Marlins are hitting just .221 as a team against southpaws.
A right-handed-hitting possibility to play left field now is infielder Donovan Solano.
Solano took fly balls in batting practice on Thursday.
"A lot happens. It's a long season," Guillen said. "I wish I could have them in the lineup. But I don't. I don't worry about that. I worry about the guys we have in the lineup."
