PHILADELPHIA -- Ozzie Guillen isn’t sure whether he’ll laugh or cry when the Marlins visit U.S. Cellular Field next season to face the Chicago White Sox.

“How am I going to feel?” asked Guillen, who was both a player and a manager for the White Sox. “I have to wait and see. I might feel weird. Maybe I won’t care. Maybe I’ll start crying. Maybe I’ll be nervous. I don’t know.”

The Marlins’ trip to Guillen’s old haunt, slated for May 24-26, is one of the highlights contained in the 2013 schedule, which was announced Wednesday.

The Marlins will open the season in Washington on April 1 and play their home opener on April 8 against Atlanta.

With Houston moving to the American League, next season’s schedule contains a number of quirks.

The Marlins will play back-to-back, two-game series — home and away — against the Tampa Bay Rays in late May.

They’ll end their season at home in late September against an interleague opponent, the Detroit Tigers. In addition to the White Sox, Rays and Tigers, they will also take on Kansas City and Minnesota in interleague competition.

“I grew up in that ballpark,” said Guillen, who played for the White Sox for 13 seasons and managed them for eight. “I was raised in that yard.”

Murphy out

Donnie Murphy is out indefinitely with a concussion, one he sustained in Wednesday’s loss to the Phillies when Chase Utley’s leg struck him in the head on a play at third.

The injury occurred in the sixth inning when Utley slid into third base on John Mayberry Jr.’s RBI single.

Murphy remained in the game and batted once more, but came out after that due to dizziness.

“I’ve been hit in the head before,” said Murphy, who was noticeably groggy.

“I thought it was one of those things you shake off with a little time. But even during that bat and right after, it just wasn’t feeling right.”

Murphy was examined by a physician at Citizens Bank Park and said he would likely be re-examined on Thursday in Miami.

The Marlins are carrying only 12 position players on the roster. If Murphy has to miss time, the Marlins would possibly bring back infielder Gil Velazquez.
