Luis Cruz vs. Juan Carlos Burgos
This fight is underway. Burgos lands a couple of combinations to the body, while Cruz is looking a little bit hesitant in the early going. Now Cruz lands a couple of good shots to the head of Burgos. A pretty even first round, but I'll give it to Burgos 10-9.
Burgos has some swelling on his eye and nose; Cruz hit him hard in the face in the first round. It's a tough fight to judge because Burgos is throwing more punches, but when Cruz throws he's more effective. Burgos lands a big left hook at the end of the round but overall Cruz's punches were more effective in a close round that I'll give to Cruz, 10-9.
Cruz's jabs are getting more effective, while Burgos keeps throwing but not always landing. And now Cruz backs away with his head up and his hands down, and Burgos makes him pay with a left hook. Cruz landed a left hook just before the bell but I'll give the third to Burgos, 10-9.
Burgos appears to be the more comfortable and confident man in the ring right now: Cruz looks a little hesitant and not eager to let his hands go. The more active man is Burgos, 10-9.
Burgos is much more effective in this round, as Cruz is still hesitant, slowing down and not landing his punches. Burgos is taking control of this fight. Burgos, 10-9.

For some reason Burgos isn't attacking Cruz's body as much now, and Cruz is taking advantage of that by wading in and connecting to Burgos's head. Good round for Cruz, 10-9.
This fight is getting closer as Cruz is now the man who looks more comfortable, and Cruz also appears to have better cardiovascular conditioning. This fight is getting interesting as Cruz is attempting a comeback. Cruz, 10-9.
Burgos lands a couple of good punches in the round, and Cruz hardly does anything, and in a slow-paced ninth that means it's Burgos, 10-9.
Cruz looks like he knows he's behind, and he's really pouring it on in the 10th. Cruz is going hard but I would have liked to have seen more of this earlier in the fight. I give the 10th to Cruz, 10-9. I'll tell you what the judges say in a minute.

This fight is underway, and Prescott is on the attack. Alvarado is holding his hands up over his face and in a defensive posture while Prescott is the one throwing punches. Prescott, 10-9.
Now Alvarado is getting more active and it's paying off, landing punches of his own and slowing down Prescott's attack. Alvarado, 10-9.
Prescott has snapped Alvarado's head back with a couple of stiff jabs, and Alvarado is back to his defensive posture. Prescott got warned for a low blow, but that was just about the only thing he did wrong in this round. Prescott, 10-9.
Prescott swarms at the start of the fourth, landing hard punches and cutting up Alvarado's face. Alvarado has a lot of blood on his face and is just trying to block while Prescott is landing big, hard punches. Alvarado can do nothing but cover up. He's got blood all over him and Prescott is teeing off. Alvarado did land a left hook that briefly slowed Prescott down, but Prescott is brutalizing him in this round. I wouldn't argue against a 10-8 round, although I'll stop just short and score it Prescott, 10-9.
Alvarado shows a lot of heart here and lands a hard left as the blood continues to drip down his face. But Prescott comes back from that and lands a combination, then sticks and moves and makes Alvarado chase him. Now Prescott has made the blood start gushing from Alvarado's mouth. A better round for Alvarado, but it still goes to Prescott, 10-9.
You've got to hand it to Alvarado for a great round of action, landing some hard uppercuts and not backing away from the inside fighting, but Prescott is the more effective puncher, and the round once again goes to Prescott, 10-9.
Alvarado is starting to come back in this fight, and he's landed a couple of good punches and is starting to cause some swelling around Prescott's eyes. It's amazing, given how beaten up Alvarado's face is, that Alvarado is still in this fight at all, let alone winning a round, but I give this one to Alvarado, 10-9.
I'm extremely impressed with the way Alvarado is coming back in this fight, landing many more punches now than he was early on. I don't know where this Alvarado was before, but it's another round for Alvarado, 10-9.
A very close and even round in which Alvarado is continuing to show a lot of heart but we're now seeing more of the Prescott we saw early in the fight, landing good shots and landing them quickly. It's a close one that I'll give to Prescott, 10-9.
