MIAMI -- Some roster shuffling is starting to take place with the Marlins.
On Wednesday, the club outrighted infielders Donnie Murphy and Nick Green to Triple-A New Orleans. But both declined the assignment, instead opting to become free agents.
Murphy, 29, made Miami's Opening Day roster as a utility infielder. He appeared in 52 games, and batted .216 with six doubles, two triples and three home runs in 116 at-bats.
The Marlins designated Murphy for assignment on June 10, and he ended up playing in 33 games while batting .302 for the Zephyrs.
Murphy was called up by Miami on July 27, two days after Hanley Ramirez was traded to the Dodgers. He saw time at third base, but on Aug. 7 went on the disabled list with a left hamstring strain.
Green was promoted from New Orleans on Aug. 4, where he batted .344 in 63 games. The veteran played some third base for Miami, appearing in seven games, batting .174 in 23 at-bats.
But on Aug. 16, Green went on the disabled list with a sprained left thumb, and he missed the remainder of the season.
Green's thumb is now fine as he weighs his options.
The Marlins 40-man roster is at 39 with four players on the 60-day disabled list.
