NEW YORK -- Left-hander John Lannan threw a bullpen session on Monday without having any problems with his left elbow. He let it go by throwing between 60 and 65 pitches.

The team's trainers and pitching coach Steve McCatty were on hand to make sure Lannan was able to throw his full repertoire of pitches -- curveball, slider, fastball and changeup -- which he did.

Lannan, who missed a start because of elbow discomfort, is good to go against the Rockies on Thursday night.

"Everything was good. I was locating everything. They were looking to see if anything bothered me," Lannan said. "When I missed a spot, I came back, I fixed it. There was no pain or anything. I was able to throw the pitches. I'm ready for Thursday."

Though it is expected to be cold in Colorado, Lannan doesn't think he will be on an innings limit.

"I don't even know. I don't think so," he said. "I would hope they would let me go, depending on how the game plays out. I may be OK because of the cold weather, but we'll see."

In addition, Lannan is now wearing a compression sleeve, which he says makes his arm feels better when he throws.

"I'm going to start wearing it because it feels better," he said. "It's something the trainers ordered. I tried it. It feels good, so I'm going to wear it."

Nationals release outfielder Daniel

WASHINGTON -- Two years ago, outfielder Mike Daniel was considered one of the best hitting prospects in the Nationals organization. Not anymore. On Monday the Nationals gave Daniel, 25, his unconditional release after he went 10-for-52 (.182) with a home run and seven RBIs.

"He didn't develop," general manager Mike Rizzo said. "It happens all the time. We felt it was time for him and us to turn the page and give him different opportunities [somewhere else]."

Daniel's best season in the organization was in 2007, when he hit a combined .294 with 11 home runs and 78 RBIs for Class A Hagerstown and Class A Potomac.

Bruney a one-inning pitcher?

NEW YORK -- Reliever Brian Bruney has had a problem pitching more than one inning this season. When he throws one inning, or in the first inning of a game in which he appears, Bruney has allowed six runs in 15 2/3 frames (3.55 ERA). When he pitches into a second inning, he has a 37.50 ERA (five runs in 1 2/3 innings).

Bruney declined to talk about these stats, but pitching coach Steve McCatty is aware of the numbers and, depending on the situation, the team may consider Bruney to be a one-inning reliever.

"Maybe there is something going on in his mind. I really couldn't tell you. It's not what you want, but that has been the case," McCatty said. "Is it a possibility of Bruney pitching the one inning? That would be tough to say. If a situation came up, where Tyler Clippard was down in that game and we needed Brian to come in to get out of the seventh for an out or two, then what do you do about the eighth? It's not just saying, 'Well, I've done my job to get out of this inning.' You have to continue on in the next inning."

Norris back in action

NEW YORK -- Class A Potomac reinstated catcher Derek Norris from the seven-day disabled list on Monday after he'd done a stint on the DL because of a sore left hand.

In his first game back, Norris went 0-for-4 against Winston-Salem.

Norris is considered the team's best hitting prospect. Last year he hit .286, with 23 home runs and 84 RBIs.
