It's just a guess, but Washington Nationals manager Davey Johnson put out a possible timeline that would have Stephen Strasburg making his first start for the Washington Nationals on September 2. Speaking to reporters before the Nationals' game against the Cincinnati Reds, Johnson suggested that Strasburg could slip into Jordan Zimmermann's spot in the Nationals' rotation.
Via Nathan Fenno of the Washington Times:
Johnson estimated Zimmermann makes his next three starts on Aug. 18, 23 and 28. Strasburg, barring any setbacks in his recovery from the same injury, would take the next turn.That would give him two rehabilitation starts after tonight's stint of three innings or 50 pitches.
It's just a guess, so don't go buying those tickets for September 2 just yet. But given the Nationals' stated desire to shut Zimmermann down once he reaches his innings limit, it's certainly a plausible scenario for Strasburg. Keep your calendars open for that date.
