VIERA, Fla. -- Nationals right-hander Doug Fister was scheduled to pitch Friday against the Astros at Space Coast Stadium, but he was scratched because of right elbow inflammation. Fister started feeling tightness in the elbow after his start against the Marlins on Sunday.
Fister had an MRI taken Thursday and it revealed the inflammation. He will rest a few days in hopes that the inflammation will go away.
"We are not concerned about it," manager Matt Williams said Friday. "If the season started [today], he could go. He could pitch, but we are not going to take any chances.
"We will push him [back] a couple of days and redo the pitching schedule. We'll make sure he is good next time out, that's all."
Fister made his Nationals debut on Sunday against Miami and allowed a run in two innings. After the game, he said he needed to work on his command.
"Overall, not bad," Fister said Sunday. "Obviously there are still a lot of things I need to work on. The biggest thing is my command. I felt a little erratic in there. I'm trying to get to know myself again this year. A lot of it is fine-tuning the sinker."
With Fister out Friday, right-hander Tanner Roark was scheduled to start against Houston.
