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.
This all doesn't mean much for how the fight will play out, really, but it's certainly worth noting that Pacquiao is the clear favorite in Vegas. For those putting money on this fight out in Nevada, the choice has been made, and it's not a 50-50 toss-up for them.
