Funny but I had one like that last week. He was in a 60 foot round pen and refused to be caught. I just circled in the center and swung the end of the lead rope and got him running around the outside. I was determined he would run until he dropped but he was going to come to me. After about 10 minutes he tried turning in to me, I kept him going and the 3rd time he turned in to me I gave up. I just walked up to him, clipped the lead rope to his halter , told him he was a good boy and walked him into the barn.
Last night he went to pull the same crap but only made one round, one round and turned into me. I walked up and lead him away.
I would run his sorry butt until he dropped or turned in begging to be taken. In a round pen he hasn't a chance.
For some reason, I find most people here disagree with chasing a horse that doesn't want to be caught, but it is really the easiest way to teach them, and I've never once had it backfire.
If he wants to run, then fine. Make him run. And the horse will think it's all fun and games for the first few minutes, but he's going to get tired and want to stop. Making him run takes the "game" away. Because now, he's working, not playing. So chase him, and watch for signs of submission; lowering his head, licking and chewing, keeping an ear on you, turning his head in, etc. Keep him going a little longer, then ask him to woah and go get him. If he goes to move away, even a STEP away from you, send him off again.
I also suggest doing changes or directions as well to get him really working off you. And like smrobs said, make sure you have time to chase him for two hours or more [it took my mare two hours the first time], because once you go in there, you HAVE to catch him, or it'll just make it worse.
And just for the record, I've done this with TONS of horses, and none of them have ever even looked away from me when I go to catch them. My mare now wouldn't dare turn her butt to me. Most of the time she will come to me. Sometimes she stands and waits, but she doesn't run away.
