CLEVELAND -- Sending Gaby Sanchez to Triple-A New Orleans has caused the Marlins to make some shifts at first base.

Manager Ozzie Guillen on Sunday said Logan Morrison and Greg Dobbs will be expected to see most of the time at first.

Morrison, groomed as a first baseman, was switched to left field when he broke into the big leagues in July 2010. He's been the team's regular in left ever since.

Against the Indians on Sunday, Morrison made his first start of the season at first base.

Earlier this year, Morrison previously saw action at first three times, as part of double-switches. He entered the series finale with the Indians having played 7 2/3 innings this year at first. The only other start at first in his career came in 2011.

"It's a funny thing about people, who think how easy it is to play first base," Guillen said. "It's not easy."

There is a feeling that playing first base will help Morrison's knees. The team has closely monitored his right knee, which underwent surgery last December.

Guillen says playing first base could be more of a grind on Morrison's legs.

"On every play that happens on the field, the first baseman has to move," the manager said. "Is that going to be easy for his legs or his knee? I don't know about that. A lot of people say, 'If you play LoMo at first base, his knee is going to be better?' No it's not.

"Each pitch you're moving. If you stand up in left field, if they hit it, there you go. First base, every pitch you're moving. Lateral. Back and forth. In and out. There is a lot of moving there. You get involved in the game more. I guarantee you LoMo is going to be sore."

Infante leaves team after death in family

CLEVELAND -- For at least three games, the Marlins are expected to be without second baseman Omar Infante.

Infante learned on Sunday morning that his grandfather had passed away. The veteran has been excused by the team to travel back to his native country, Venezuela, for the funeral.

Initially, Infante was in the lineup, batting second on Sunday in the series finale against the Indians at Progressive Field. But shortly after arriving at the ballpark, Infante informed the organization.

Donnie Murphy was given the start at second base in Infante's place.

"[Infante's] grandfather passed away this morning," manager Ozzie Guillen said. "I expect him to be back in three days, I guess. I don't know."

Infante has been the team's most consistent hitter, batting .326 with six home runs and 20 RBIs.

"We're going to keep in touch in the next couple of hours," Guillen said. "It's a tough situation. That happened to me a few years ago."

After completing their series at Cleveland on Sunday, the Marlins will return to Marlins Park to face the Rockies next week. Perhaps Wednesday will be the day Infante is back.

Along with Murphy, Donovan Solano is a candidate to play second base.

Solano was called up on Sunday from Triple-A New Orleans, marking his first appearance on a big league roster.

"Murphy is going to play today, and we'll see what happens in the next couple of days," Guillen said of filling in at second.

As a team, the Marlins are now without Infante and center fielder Emilio Bonifacio, who was placed on the 15-day disabled list on Sunday with a sprained left thumb.

"We have to overcome," Guillen said. "We've got to be tough."

Marlins think Gaby's Minors stint will be short

CLEVELAND -- Gaby Sanchez's stay at Triple-A, the Marlins hope, will be a short one.

The team believes it is a better club with Sanchez playing first base in the big leagues on a regular basis.

But with Sanchez scuffling with a .197 batting average to go with one home run and 11 RBIs, the team on Saturday decided to option the 28-year-old to New Orleans.

Barring a disabled list stint, a player must spend at least 10 days down before being eligible for a callup.

Manager Ozzie Guillen said on Sunday, that the organization would like to see Sanchez get back into his groove and then rejoin the club in less than two weeks.

"Hopefully, he gets his stuff together and he gets back here," Guillen said. "I talked to him last night. I said, 'We need you here. This ballclub was built with you in the lineup every day.' I will be waiting for him. This is not a punishment."

Sanchez was an All-Star in 2011, in a season he appeared in 159 games.

But he's had a hard time finding consistency in his 122 at-bats this year.

"We've been talking about this for a little while," Guillen said of sending the first baseman down. "I think Gaby got to the point where he needed to relax a little bit. It got to the point where he tried to help us so much. It was a very tough situation.

"I think he was trying too hard. He was rushing. He was trying to come out of the slump with one at-bat."

Mujica's return to Cleveland brings back memories

CLEVELAND -- Returning to Cleveland for Interleague Play gives Marlins reliever Edward Mujica a chance to reconnect with some of the people who helped launch his big league career.

Mujica broke into the big leagues in 2006 with the Indians.

In fact, in his MLB debut on June 21, 2006, the Indians were facing the Cubs, who started Carlos Zambrano.

"I was here for three years," said Mujica, who was traded to San Diego after the 2009 season. "I learned a lot about this job, especially in 2006 when I got called up my first year. I am thankful they gave me an opportunity here."

Indians pitching coach Scott Radinsky was Mujica's pitching coach in Triple-A. And Dave Miller, Cleveland's bullpen coach, was the organization's Minor League pitching coordinator when Mujica was in the system.

Mujica is one of the Marlins most dependable relievers. He's the primary eighth inning setup right-hander.

In 20 games, he has four holds and he collected two saves earlier in the month when Heath Bell was not available.

While coming up with the Indians, Mujica was given tips on throwing a split-finger fastball and his changeup.

"It was big to learn that, because my changeup right now is one of my better pitches," Mujica said.
