There would be no positive end to Tim Lincecum's nightmare first half, no signs that his old form will return as the season hits the stretch run.

Lincecum lasted just 3?1/3 innings Sunday in a 13-2 loss to the Pittsburgh Pirates, his 10th defeat of the season. The two-time Cy Young Award winner heads into the All-Star break with a 6.42 ERA, the highest in the majors.

"You never want to say I've hit rock bottom or anything like that, but when things are going as bad as they are right now, you've got to go out there with the feeling like you've got nothing left to lose," Lincecum said. "I have to erase this, obviously remember it and use it to know what I don't want to go through again.

"It's been terrible. It's a terrible feeling. When you're the weakest link, that wears on you."
