When Santos is in stroke, he plays as good as anyone in the world. When he first came to the US, he played at the same poolhall as me. We became friends and he would give me lessons. I was present when he gave Jennifer Chen the 6, 7, the last two, and the breaks for $2000 a set, race to 11. He beat her both sets by a large margin, something like 11-5 and 11-4 IIRC. At the time Jennifer was ranked in the top five in the WPBA. And she didn't play bad in both sets! Santos rarely left her a shot. That was some of the best pool I've ever seen. The sad part is that with all his backers, Santos only got like $300 out of it!!! LOL.... Santos played some shots that were just ridiculous...Efren-esque, as I like to call it.
I also saw him lose a few thousand to Shannon Daulton a few years ago. Santos played horribly, and at the time Shannon was on top of his game. It was right after a tournament at the Crystal Park Casino in LA. When he plays bad, well, he plays bad (just like any pro). But if he's playin good, I would definately bet on him. IIRC I saw Chavez play once, and he impressed me. Nobody knew who he was, but he was playing jam up!
Chavez better have a strong break, because little Santos can smash the hell out of the rack!
