The Washington Nationals' decision to shut down Stephen Strasburg has consumed the baseball world for months, and Friday night, as the countdown whittled to one start, it may have consumed Strasburg himself.

In what the Nationals planned to be his final appearance at Nationals Park and penultimate start of the season, Strasburg surrendered five runs over three ragged innings in a 9-7, 10-inning loss to the Miami Marlins. He allowed six hits, three walks and two homers to the same lineup that battered him two starts before.

The Nationals overcame a four-run deficit to force extra innings, a rally capped by Michael Morse's solo homer in the eighth. They nearly erased the three-run lead the Marlins took in the 10th inning against closer Tyler Clippard. But afterward, with their lead in the National League East sliced to 61 / 2 games, Manager Davey Johnson worried more about his ace than he celebrated his team's effort.

Strasburg became so concerned about letting teammates down he had trouble sleeping in recent nights, Johnson said. Strasburg still rejected the idea that anything but a poorly located fastball undid him. Johnson sensed otherwise.

"To be honest with you, I think he was thinking too much about the decision" to end his season early, Johnson said. "And he kind of wore it. .?.?.But that's the way it is. I think he wasn't focused as much on the game as he was on the impending shutdown. Just the way I read it."
