Washington is a terrible club and seeking solutions and will overuse Strasburg

Strasburg’s first outing was excellent, so the club is not likely to turn back to a more patient course with this pitcher.

Baseball history has a long list of pitchers who came out gangbusters Dwight Gooden, Steve Busby, Wally Bunker, Mark Fidryich, and more but faded rapidly usually due to arm woes. If I recall correctly, Bill James said the only HOF pitcher to have impact as a rookie was Tom Seaver.
