"He feels great. We're by [his forearm issues]," manager Davey Johnson said. "We're set to go for [Thursday]."
Johnson said Friday that Strasburg felt the tightness after experimenting with a new pitch. Strasburg said the new pitch is "nothing crazy," and said he isn't sure whether it caused the injury.
"I think I was trying to stretch it a little bit too aggressively," Strasburg said. "I've been messing around with pitches all year. The trainer said when you try to stretch it too much, your body's natural reaction is to tighten up, which is what I was feeling.
"I know not to do it in September next year."
