I am perplexed by the line move on the OAK / DET game today. OAK opened at -160 and is now -136!! A's pitcher Hill pitching very well this season and Det. pitcher Pelfrey not pitching well. And Tigers have a team BA of just .211 with an avg of just 3.3 runs per game vs Lefty starters this year!!...???..........Anyone out there got a clue?
