ALBUQUERQUE, N.M. - The second of nine 15/15 Bucking Battles takes place tonight at The Pit, and will be broadcast tomorrow at noon ET on CBS.

Caleb Sanderson on 961 Mac-Nett's Southern Wine:
This is a bull who, like Chicken on a Chain, had quite a bit of history at the Touring Pro Division level before he came to the Built Ford Tough Series. Sanderson actually had him in January of 2011 at a Touring Pro event, and received a re-ride due to a foul. He's only been ridden three times in the past year, and two of the victors were larger, right-handed riders - Aaron Roy and Valdiron de Oliveira.

Jordan Hupp on 13/6 Bushwacker:
This is the rankest bull in the world right now. You could make an argument that his number may soon be up, because J.B. Mauney rode him 7.22 seconds in Arlington, Texas, but that was Mauney's seventh effort. It took him six practice runs to get that far. This will be Hupp's first shot. Even at this level, riders just don't face bulls like this very often. Everything that bulls do, Bushwacker does better. He's like the guitar amp that goes up to 11.

Ty Pozzobon on 601 Shepherd Hills Trapper:
Trapper with Marco Eguche in Arlington had one of the most difficult outs a bull can possibly have. As tough as he looked, there's a very simple strategy for success on this bull: Just stay off his head. Riders tend to subconsciously focus on getting their upper bodies back to the front, because bulls that work against that are very common, and it is a part of rider form that requires some discipline and effort to master. It's an unnecessary effort on this bull, because Trapper wants to flip the rider right out over his shoulder - the issue is not letting him do that. With Eguche, this bull also had giant rolls, and those are a different issue - the main problem riders will have with this bull is staying off his head. To a lesser extent, Jack Daniel's After Party, who will face Chris Shivers in this round, is the same way. In a way, Austin Meier, who can ride with great balance and a feel for where he is while sitting straight up or even out of shape, is the perfect match for this bull, because staying in perfect position will be almost impossible.

Justin Koon on K55 Smackdown:
Smackdown is one of the toughest bulls going today for right-handed riders specifically, but Koon does have one thing going for him - he's been on this bull before. They met at a rodeo in 2010, where Koon stayed aboard for 6.4 seconds, which is about as far as any right-hander has ever taken Smackdown. Reese Cates lasted 6.43 seconds on him once last season, and Douglas Ferreira rode him at the World Finals, but Smackdown did turn back to the right that day.

Luke Snyder on 924B Jack Daniel's Tennessee Honey:
As tough as Smackdown is against right-handed riders, this bull may be tougher. He's never been ridden by a righty, and Snyder is one of his victims. They met in Oklahoma City in 2010. Honey is the polar opposite of Trapper; he doesn't want to throw anyone off over his head; he wants to fling them straight out the back like a Frisbee with arms and legs.

L.J. Jenkins on 705 Back Bender:
These two met here last year in the Built Ford Tough Championship Round, and Jenkins came down before the whistle, but already had the event won. Only three riders have earned a score on Back Bender, all of them right-handed.

Guilherme Marchi on 5403 Perfect Poison:
Perfect Poison has been ridden four times in 31 career outs, always by left-handed riders. He's not particularly predictable, except that he's always difficult to ride and does not buck with a steady rhythm, making it hard for riders to stay in time with him.

Chris Shivers on 868 Jack Daniel's After Party:
Jack Daniel's After Party has been a tougher bull for most of this season than he was in the second half of last year. He had a nice trip with Ryan Dirteater in Atlanta, and that's the only time he's been ridden this year. He likes to go to the right, which will be away from Shivers' hand. This bull is extremely quick, stays close to the ground and can plant and turn far more quickly than most bulls. A rider may be in perfect position, then find himself looking straight up one of After Party's nostrils in the blink of an eye.

Ryan Dirteater on 107 Rock & Roll:
This bull is unridden in 19 career outs. His defining characteristic is that he tends to cover a lot of ground. Bulls who use up a lot of arena space are difficult to ride because riders simply have a hard time keeping up. A great many world-class bulls can do their thing in a rather small area, but this one is going to see what there is to see before he remembers to "take a left in Albuquerque."

Austin Meier on 5081 Highway 12:
Meier has tried Highway 12 twice, and was forced to take an unexpected detour both times. I think this is a bull who merits some study on the part of the riders. He isn't visually a standout among short-round-caliber bulls, but he's working on a streak of 11 straight buckoffs going back to September of last year, and in that time, he's been tested by some pretty salty riders.

Renato Nunes on W1 Buckey:
These two make a rather odd couple, like a gymnast squaring off against a defensive lineman. Buckey is tough for left-handed riders. He likes to go to the right, and he tends to do it with authority. Buckey can get any rider to the end of his riding arm, and Nunes tends to get to the end of his arm quite a bit and get away with it, but he's not likely to here.

Silvano Alves on 01B High Octane Hurricane:
High Octane Hurricane hasn't been ridden since September of last year, and hasn't been ridden on the Built Ford Tough Series since March of 2010. That streak may be coming to an end, though. Alves has ridden his past 9 bulls in a row, and like every rider who has ever ridden this bull, is right-handed.

Marco Eguche on 20T Train Wreck:
This pair makes for a pretty good matchup. Train Wreck is one of the more exciting bulls to watch, and Eguche is more than capable of making the whistle. Getting out of the chute clean and getting in time in the first few jumps are the major issues on this bull.

Valdiron de Oliveira on 789 Bad Blake:
Bad Blake has only been ridden three times, and Oliveira is one of the three riders. He got it done in the short round in New York earlier this year. Oliveira is five for his past 10 bulls, which is better than some riders ever do, but below par for him. He's due to break out.

J.B. Mauney on 718 Rango:
This has the makings of an epic matchup. Rango has only been around a little over a year, but he is the real deal. He always bucks hard, and has taken on an impressive list of the world's toughest riders and whipped all of them except Meier. Mauney is known as a kind of dragon-slayer among riders, and he's got a real dragon to slay here.

CATCH THE ACTION: There are effectively two competitions this weekend: The Ty Murray Invitational, and the 15/15 Bucking Battle. The points from the Battle do not count toward the outcome of the Ty Murray Invitational, which is a regular-season event. The 15/15 Bucking Battle will physically take place tonight at The Pit, and can be seen Sunday on CBS at noon ET (Please note this is regular CBS, not CBS Sports Network, and that noon ET is much earlier than our usual broadcasts - 9 in the morning for West Coast fans). The final two rounds of the Ty Murray Invitational will be shown on CBS Sports Network later the same day at 6 p.m. ET.
