WASHINGTON -- Emilio Bonifacio usually plays center field for Miami, but he made his first start of the season at second base on Saturday.

Bonifacio played the first 14 games in center, but manager Ozzie Guillen shifted him over to second base during the eighth inning in Friday's 2-0 series-opening loss to the Nationals.

Second baseman Omar Infante won't be starting in this series due to his strained groin, and Guillen said he's fine with how Donnie Murphy's playing there now.

"Bonifacio, he's not going to do it every day," Guillen said. "I'm just doing that because ... [Chris] Coghlan is swinging the bat pretty good right now. I want to take advantage. I think Murphy's been playing great."

Bonifacio played five games at second base last year out of 152. But he's played there on a regular basis throughout his career, so Guillen said he's fine with moving him over to second.

The skipper also was trying to get some more left-handed bats in the lineup against Washington right-hander Stephen Strasburg. Miami had five left-handed bats in the lineup, including the switch-hitting Bonifacio and Jose Reyes, as well as Coghlan, Logan Morrison and Greg Dobbs.

"We're going to face one of the better righties in the game," Guillen said. "Hopefully those left bats make things happen."

LoMo returns to starting lineup after night off

WASHINGTON -- Left fielder Logan Morrison returned to the Marlins' lineup for Saturday's game, as the team is taking things slowly with him due to recurring right knee issues.

Morrison had offseason surgery on the knee, and manager Ozzie Guillen said the Marlins are keeping a close eye on him.

"We've got a plan for him," Guillen said. "It's a process. Hopefully it's a process for two months, a month and a half, then we see how it is after that. [If] he's better, completely better, [then] we see how we're going to play him."

Morrison was batting fourth against Washington starter Stephen Strasburg. Entering the game, Morrison was batting .300 with five RBIs.

"It's a day-to-day thing with my knee," Morrison said. "They give me days off just to make sure it doesn't get worse. Hopefully [it] gets better as the season goes on."

Morrison got a pinch-hit single in Friday's 2-0 loss to the Nationals, but he didn't play in the field. He batted for starting pitcher Carlos Zambrano, but was back in left on Saturday.

"I'm good enough to go," Morrison said.

Ozzie emphasizes pitching in tough NL East

WASHINGTON -- Marlins manager Ozzie Guillen said he expects to see more games like Friday's battle with the Nationals -- when the pitching is very good and final scores are close.

Washington scored a 2-0 victory over Miami on Friday night, thanks to a few big hits and strong pitching.

Before Saturday's National League East battle with Washington, Guillen said the division's good pitching will probably force a lot of tight games.

"[I] expect close games most of the time," Guillen said. "We know that our division's pretty good."

But Guillen said his pitching staff, ranked sixth in the NL in ERA, has impressed with its early work. That's the kind of thing good teams need to have a shot at being competitive.

"I'm very excited about the way we play," Guillen said. "We're pitching well. That's very important."
