Nats' Strasburg has twisted left knee

WASHINGTON -- The Washington Nationals say No. 1 overall draft pick Stephen Strasburg has a twisted left knee and is being scratched from his start in the Arizona Fall League championship game.

Strasburg was hurt during a workout Thursday, and an MRI exam showed inflammation. He is scheduled to travel to Washington on Friday to be examined by the Nationals' team doctor.

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.
