ANAHEIM, Calif. - There are a few debut bulls out tonight, and many of the top riders have one - J.B. Mauney, Chris Shivers, Guilherme Marchi, Kody Lostroh, Renato Nunes and Caleb Sanderson among them.  One or more of these newcomers will likely be good enough to win the round on. Scores of 87 points or better should get paid in this round.

Austin Meier on 45-07B Rainbow:
Meier did not get off to a great start in New York, but he will start to make up for it here. Rainbow is a great draw, and has been ridden in five of seven Built Ford Tough Series outs. Left-handed riders are 3-for-3 on him.

Douglas Duncan on 260 Damn Right:
"Damn Right!" is what riders say when they find out they have him, because he has yet to buck off a rider at this level, and can deliver 87 to 88-point scores.

Meier did not get off to a great start in New York, but he will start to make up for it here.

Harve Stewart on 772 Stinkeye:
Riders are 2-for-2 on Stinkeye at this level for great scores. Stewart is looking to become more consistent, and this is the kind of bull that should help him. Even with only three career outs to go on, Top-10 caliber riders would be heavily favored to get a score on him.

Marco Eguche on 683 Motown Magic:
There are a lot of new bulls in this round, but among the bulls with Built Ford Tough Series experience, this is the highest scoring bull. He's also been ridden several times. You may not have heard of Eguche, but he competed at Chicago and Kansas City, Mo., last year, and has ridden 59 percent of the bulls he's faced in the United States, including three of the five he got on in New York last week.

Ryan Dirteater on 64/7 Mr. Feiger:
This is a new bull with only a couple of outs in his career. He is a son of Reindeer, and half-brother to Bushwacker. He was scored 45.5 points at a Touring Pro Division event last August, then fell with Cord McCoy, also in August. He earned 42.25 points with Shivers at the World Finals. Given his family ties, and that record, this could be an exciting bull to watch.

Mr.Feiger bucks offf Chris Shivers at the 2011 World Finals.

Silvano Alves on 8T Mr. Smith:
Alves should get his fourth bull of the season ridden easily. This is a debut bull, but he went to a number of Touring Pro events last season. This will be the most talented rider he's faced, and he will probably not have enough to get Alves on the ground.

Cody Nance on 10725/7 Remington:
Remington only made it to three events last year, and was ridden by Jared Farley in April. Nance not only won in New York last week, but he did so in high style - without any real technical mistakes the entire weekend. Bull riding is all about reaction to what the bull does, and Nance had the correct reaction for every jump on every bull he got on. That is an awful lot harder in practice than in theory.

Mike Lee on 64 Merlot Man:
This bull has a perfect record. All 14 riders who have faced him have earned identical scores of zero. He's recorded some impressive bull scores along the way, but hasn't really faced riders of Lee's ability, so this is a step up for the bull. We'll have to see if he has what it takes.

Stormy Wing on 51 Night Rider 6:
Wing has a good draw here. Night Rider 6 has been ridden in 10 of 25 outs overall, and in four of seven outs on the Built Ford Tough Series.

This one is a test for Snyder.

Luke Snyder on 7032 Snowstorm:
Snyder has been the center of attention for a while, because of his success last season and in New York last week. When Snyder first came into the PBR over 10 years ago, he clearly had the talent to compete for a World Championship, but it never came to pass. Last season, Snyder returned to his early form. This matchup will be interesting to watch, because this bull's record is rather ugly in terms of allowing qualified rides. For a rider to really compete at the highest levels, he has to ride all the good draws, and most of the bad draws. This one is a test for Snyder.

Aaron Roy on 5BB Little Brother:
This bull does get ridden quite a bit, but more often by left-handed riders. Roy had him in Sacramento, Calif., last season, and came down in 2.51 seconds.
