Washington Nationals pitching phenom Stephen Strasburg could be shut down for the rest of his rookie season after leaving Saturday's game against the Phillies. Strasburg winced in pain after throwing a pitch in the 5th inning. He underwent an MRI today and the team is waiting for the results before they decide how to proceed. Strasburg has already been on the disabled list with shoulder inflammation. He's been on a strict innings count for his first professional season so it's possible the Nats will shut him down early to avoid further injury.

Strasburg started the season in Harrisburg with the Senators before he was promoted to Triple AAA Syracuse and then the Nationals. Strasburg has 92 strikeouts in only 68 innings in the Major Leagues but only has 5 wins to go with 3 losses.
