Stephen Strasburg leaves mound with an injury

Nationals' starting pitcher and key to the franchise's future, Stephen Strasburg, left the mound in the 5th inning Saturday night in visible pain after throwing a change up. Following the pitch Strasburg clearly recoiled in pain, first with a facial grimace and then by shaking his arm as if he had strained his elbow or forearm.

Through 4.1 innings, Strasburg had struck out six batters while only allowing two hits and one earned run. He had only thrown 56 pitches on the night.

While it may be too soon to speculate, this could be the last we see of Strasburg in 2010...probably not due to physical restrictions...but likely as a precaution.

Update - 10:20 P.M:

Mark Zuckerman tweets that Strasburg suffered a strain to the flexor tendon in his forearm,  sill have an MRI tomorrow.
