MIAMI -- At the earliest, Omar Infante could return to the Marlins' lineup on Tuesday. But that is far from being a sure thing, according to manager Ozzie Guillen.

Infante's grandfather passed away on Sunday.

The second baseman heard the news before the team faced the Indians, and he immediately made plans to return to Venezuela for the funeral.

Donnie Murphy, who started in Infante's place on Sunday at Cleveland, was back in the lineup at second on Monday in the series opener with the Rockies at Marlins Park.

"He should be back [Tuesday]," Guillen said. "You never know what is going to happen from one day to another in Venezuela. Plane may be late. I'm not counting on him for three or four days. He's not in my mind right now. I've got to wait and see when he gets here."

Infante is having an All-Star caliber season, batting .326 with six home runs and 20 RBIs.

Ozzie, Perez reflect on Moyer's long career

MIAMI -- Jamie Moyer's longevity has reached a wide range of people in the Marlins' organization.

You can consider the fact Moyer, 49, has faced 22-year-old Giancarlo Stanton as well as Hall of Famer Tony Perez.

Perez, a Miami special assistant, turned 70 on May 14.

Manager Ozzie Guillen was 4-for-22 in his career against Moyer.

"When Tony told me he faced him, I don't think Jamie Moyer is 50," Guillen joked. "I think he's like 58. If Perez faced him, come on, wow! You better check his birth certificate."

Actually, Moyer turns 50 on Nov. 18.

Perez was hitless in three at-bats while facing Moyer in 1986.

"I don't remember. He was a rookie," said Perez, who was 0-for-3 in those encounters.

"I never want to hit a young kid," Perez joked. "He was just coming in, and I wanted him to stick around. You see, I made him stick around. Facing a guy who is almost 50, it doesn't make me feel any younger. Right now, with the way he throws, I feel like I can face him again."

Moyer reached another milestone on Monday when he pitched at Marlins Park, which is now the 50th park the left-hander has played, the most of any Major Leaguer.

Miami special assistant Jeff Conine faced Moyer and was his teammate in Philadelphia in 2006.

"He worked as hard if not harder than everyone else," Conine said. "And he is prepared like no one else. Being a left-handed pitcher, he doesn't have to throw real hard. I'm not completely surprised at what he's doing.

"His work ethic is relentless. He shows up a lot of the young guys. He's ultimately prepared."

Umbrella policy changes at Marlins Park

MIAMI -- Having a roof guarantees games will start on time at Marlins Park. But the building itself isn't enough to shelter fans from the elements on their way into the Marlins' new home.

When the season started, the Marlins had a "no umbrellas" policy in their retractable-roof ballpark.

But after it was noted that fans were getting wet prior to entering the building, team president David Samson lifted the policy.

"I got an e-mail from a fan who, during a rain storm, walked from his parking spot to the ballpark with an umbrella," Samson said. "He wasn't allowed to bring it in, because we had a no umbrella policy.

"The reason we had a no umbrella policy is that there is no rain inside the ballpark at all."

The Marlins open a 10-game homestand on Monday against the Rockies. If it is raining shortly before the first pitch, fans can now bring umbrellas into the ballpark, which has a capacity of 37,000.

"I personally take the blame," Samson said. "I overlooked the fact that fans need umbrellas to get from their parking spots to get to the ballpark, because it does rain.

"So we changed the policy immediately. I got the e-mail, and the policy changed within 10 minutes."

Unpredictable rain patterns and excessive heat were reasons the Marlins sought a retractable-roof ballpark.

During the franchise's first 19 seasons, they played at spacious Sun Life Stadium. Rain repeatedly was an issue in terms of distracting fans from attending games.

"We've always said that we want to hear from fans," Samson said. "What are we forgetting or what are we doing wrong? We go ahead and act on all the e-mails we get. I get great suggestions on d.samson@marlins.com."

Morrison getting work in at first base

MIAMI -- Fielding the first grounder he handled on the heel of his glove wasn't completely comfortable, but playing first base is familiar to Logan Morrison.

The Marlins are going with Morrison at first base after Gaby Sanchez was optioned on Saturday to Triple-A New Orleans.

A first baseman coming up through the Minor Leagues, Morrison converted to left field in 2010 because Sanchez had secured first base.

Morrison played first on Monday in the series opener with the Rockies. On Sunday at Cleveland, the 24-year-old made his first start of the year at first base.

"I was just a little anxious, a little nervous," Morrison said, assessing the switch back to the infield. "But once I caught the first one, in the heel of the glove, I was good to go. I was like, that's not really where it's supposed to go. But I made the play."

Since the start of Spring Training, Morrison took ground balls at first base.

And during the season, he also got work at the position.

"Whenever I'd get a day off, I'd go over to first base and take ground balls," he said.
