Looking at the various playoff odds today I think the seller pool is starting to solidify.
NL: PIT, WAS, COL, CIN, CHC, ARI, MIA
AL: BAL, KCR, DET, OAK, TEX and SEA.
BOS is still sitting in the 30-38% range, solidly behind the top seven contenders, so looking like a good bet to end up here barring a run over the next couple months & CLE is around 10-20% so an even longer shot for them.
