I would like an inexpensive (less than $20/month) source for "year to
date" Major League Baseball game logs.  The game logs must contain, at
minimum, Date / Teams / Pitcher Names / Line (odds) / Earned Runs /
Hits / Walks / Strike Outs / Final Score.  Computer Sports World
provides year to date baseball game logs--but charges $90/month.  For
example, when Roger Clemens faces Pedro Martinez in the middle of the
season, I'd like to access all the game logs for those two pitchers.

www.retrosheet.org provides extensive game log information.  At the
end of full seasons, they compile a full-season game long with all the
info you're looking for.  They don't do year-to-date in the concise
form, but they keep box score archives that could easily be saved and
searched through with a script or something.  I suggest checking there
if you haven't already.
