I'm on Rice at -220 (line just moved in favor of Rice).
I like the Miami team as they are scrappy. They like the underdog role as motivation. However, tonight they play a team that is far better than any they faced so far in the tourney.
Rice definitely has the pitching advantage. I think it is interesting St. Clair is getting the start, but he will probably be looked to for only a few innings, just like his other start. That is fine though as they have several guys that can come into this game that have fared well as both relievers and starters (7 different Rice Pitchers started a game this year).
Considering the bats, Rice has a slight advantage. Both teams are similar in that they don't have guys that instill a ton of fear in another pitcher, but they are solid throughout the lineup.
It's a steep price, but I'm going with Rice. Good luck no matter what you play.
