After Monday's 3-2 loss to the Pirates at Marlins Park, the team announced Kevin Mattison is being optioned to Triple-A New Orleans, where he will get regular playing time in center field.
The team didn't announce who was getting called up. But it is expected to be Bryan Petersen, who is eligible to return after being optioned on May 5.
By league rule, barring filling in for a player going on the disabled list, a player optioned has to wait 10 days before being eligible for a callup. Tuesday is exactly 10 days.
Petersen was not in New Orleans' lineup on Monday.
Mattison, who was called up on Thursday, was hitless in one at-bat.
Petersen, who plays all three outfield spots, opened the season in New Orleans, and he initially joined the Marlins on April 30. In 28 games at New Orleans, the left-handed-hitting outfielder batted .320.
He appeared in four games before being sent down on May 5.
