WASHINGTON -- Stephen Strasburg is "not too happy" with the Washington Nationals' decision to shut him down after a shaky start against the Miami Marlins.

"I thought I had another start," the right-hander said after the Nationals' 7-6 win over Miami on Saturday. "It was pretty shocking and honestly, I'm not too happy about it."

Manager Davey Johnson made the announcement Saturday morning, citing the effect of the media attention surrounding the impending shutdown on the No. 1 overall pick in the 2009 draft.

"I just told Stephen that his year is over. He's had a great year. I know what he's going through," Johnson said. "The media hype on this thing has been unbelievable. I feel it's as hard for him as it would be anybody to get mentally, totally committed in the ballgame. And he's reached his innings limit. So we can get past this and talk about other things for a change."

The 24-year-old ace said he tried to talk his way into one more start.

"I talked to them about it and they seemed pretty firm," Strasburg said. "It's not just about me. It's not about one player. I think the best thing I can do now is move forward and be the best teammate I can."

The NL East-leading Nationals had said Wednesday's start at the New York Mets likely would be his final appearance of the season. John Lannan will make that start and remain in the starting rotation.

"I don't know if I'm ever gonna accept it to be honest," Strasburg said of the plan to end his season prematurely. "It's something that I'm not happy about at all. That's not why I play the game. I play the game to be a good teammate and win.

"You don't grow up dreaming of playing in the big leagues to get shut down when the games start to matter. It's gonna be a tough one to swallow, but like I said, all I can do is be the best teammate possible for these guys."

Johnson said the decision was his, and pitching coach Steve McCatty and general manager Mike Rizzo were in agreement.

"My job is to do what's best for the player. And this is what's best," Johnson said. "If you're not there 100 percent mentally -- he's a gifted athlete, his velocity can still be there -- but I don't see the crispness. I don't see the ball jumping out of his hand. I'm a firm believer that this game's 90 to 95 percent mental and he's only human. I don't know how anybody can be totally mentally concentrating on the job at hand with the media hype to this thing and I think we'd be risking more by sending him out."
