Also, Scott Christ at Bad Left Hook talks about the swing in odds for the Manny Pacquiao v. Miguel Cotto boxing event:

The Vegas lines for Saturday night’s showdown between Miguel Cotto and Manny Pacquiao opened fairly modest, with Pacquiao at -200 (bet $200, win $100) and Cotto a +180 underdog (bet $100, win $180).

But as the fight grows nearer and money piles in for Pacquiao, the line has moved. Pacquiao is right around -240 or -250 on most books, and some books have even put him down at -300 at this point. Cotto has moved to right around +190, and in some cases around +200.
