Sunday was a day the 23-year-old had his fiery temperament work against him.

The Marlins announced Monday that Olsen had received a two-game team suspension for insubordination.

Citing conduct detrimental to the team, Olsen will be docked two days pay for an undisclosed suspension. The left-hander will not miss his next scheduled start, which is Friday at home against the Reds.

While the team isn't saying what happened, a source said Olsen had a confrontation with pitcher Sergio Mitre in the tunnel heading toward the team clubhouse.

The incident occurred after Olsen was lifted from the game after the fifth inning. The Marlins won 5-2 on Sunday over the Nationals, with the left-hander working the necessary five innings to collect the win. He improved his record to 7-7 with a 5.15 ERA.

Olsen ripped his jersey off and tossed it in the direction of a trainer. Mitre and other Marlins, according to the source, took exception to Olsen's actions. That's when tensions got hot. As they were leaving the dugout area, Mitre pinned Olsen against a wall before the two were separated by teammates.

Olsen was informed of his suspension after he spoke with reporters.

Admittedly overly-emotional when he pitches, Olsen has had a number of incidents where his fiery on-field personality works against him. At Milwaukee on June 1, for instance, he made an obscene hand gesture to a group of hecklers sitting above the Marlins' dugout.

The team at that time said the matter was being addressed internally.

And as a rookie in 2006, Olsen had an incident where he was punched in the eye by teammate Randy Messenger. Shortly after that, he was grabbed around the collar by former manager Joe Girardi.

Olsen told Marlins beat writers in Milwaukee the day after his June 1 start: "I'm a different person when I'm out there."

During that interview, he noted that he doesn't really worry about his public image.

"Does it bother me? No. Not one bit," Olsen said. "People that have an opinion of me, most of them, probably don't know me. So it really doesn't bother me. They can think what they want about me, if they don't know me. In the real world, is that outside the lines? I'm fine. When I'm out there, I'm in a whole different world."
