Yeah I know -145 or whatever is a big line considering Oswalt has not been dominant this year. But I think Stults may have shot his load last time out, and Houston really hits lefties well.
If Oswalt has a meltdown this one will be toast, but if he can keep a reasonable cap on the Dodgers' scoring I think they'll pull it out.
I may make a partial hedge/partial enhancement with a bet on the over 8.5 as well.
