Strasburg was hurt during a workout Thursday, and an MRI exam showed inflammation. He is scheduled to travel to Los Angeles on Friday to be examined by Dr. Lewis Yocum.

The Nationals issued a news release saying Strasburg's injury "is not considered serious."

The title game is Saturday.

Strasburg also was held out of a scheduled start in the Arizona Fall League Rising Stars game Nov. 7 because of a strained neck muscle.

The San Diego State right-hander signed a record $15.1 million contract after being the top pick in June's amateur draft.
