At least, so it seems - Frank Shamrock could possibly still be a middleweight contender.
Now, I haven't yet seen the fight, but word on the net is that Frank handled Baroni on the feet and then put him to sleep with a rear choke in the second round. Baroni says he tore his groin in the opening moments, and that may be true, but it still sounds like he got owned.
This is exciting news - if Frank can still hang with some of the better talent, there's a chance he may get crack at the top dogs in today's middlweight division - Silva, Franklin, Henderson, Kang, etc.
Unfortunately, given their history, it seems unlikely we'll see Shamrock in the UFC (though you would also have said that about BJ Penn before he came back), and the UFC seems to be poaching the top talent of it's recent acquisition, Pride FC. Except for Dan Henderson though, no middleweights have made the move, and so there could be a good number of exciting matchups if Frank moves over to the land of the rising sun.
Of course, Ninja also just fought (and won) on the Elite XC card, so perhaps a matchup between him and Frank could be next. I know I would pay (or not and download instead) to see that one.
