Baseball Prospectus | Events | Chat with Kevin Goldstein:
"Tex Premium Lager (NJ): ETA on Strasburg callup, assuming health? Above average pitcher on the major-league level from day 1, or will he take his knocks for a little while?
Kevin Goldstein: 10 minor league starts. 4 for Potomac, 4 for Harrisburg, a couple Triple-A warmups and early June in the big leagues. Above average from Day One"
FWIW, this matches with the info Wprovided on Baseball America's recent podcast that said Potomac was already marketing ticket packages around Strasburg's stay.
