OK, here are some series that I like value wise:

Oakland (-180) vs. Seattle
Oakland is 41-9 in last 50 vs. a team with a losing record.

Cleveland (-115) vs. Washington
Washington is overrated by odds makers/Cleveland has won last 7 interleague games and traditionally kills the NL East

St Louis (-240) vs. Florida / Chicago (-220) vs. Houston
Two worst teams in baseball.

If you can parlay all 4, take it. Merge doesn't allow it, but I think BCP does
