Dave Sheinin is live blogging tonight’s game, in which Strasburg will likely throw either four innings or 60 pitches, whichever comes first.

Here are Sheinin’s takes on Strasburg’s first rehab start (Aug. 7 in Hagerstown), and his second start (Friday in Potomac).

Here’s how Sheinin summed up the Hagerstown game:

In the bigger picture, this was less a historic performance than another milestone on Strasburg’s long, grueling path back to the major leagues — a path that began with reconstructive elbow surgery last Sept. 3, when a tendon from his left thigh was transplanted into his right elbow, replacing the ligament that had blown out on a single pitch two weeks earlier.

In his first two rehab starts combined, Strasburg has allowed one run in 4 2/3 innings on five hits and no walks while striking out nine. His fastball has regularly zipped at 96-98 miles per hour, and hit 99 in his last start.
