INDIANAPOLIS - There are plenty of new or relatively inexperienced bulls in Round 1 here, and some of them are sure to figure into the outcome.

Round 1:

Matt Bohon on S06 Monsoon:
Monsoon only has three career outs, and he was ridden in two of them - in Baltimore and Atlanta earlier this season. Ben Jones was 87.5 points on him in Baltimore.

Silvano Alves on -0 Bootlegger:
Bootlegger has been around for a few years now, and he's bested about half of the top-level riders who have been on him. He's not enough bull to get Alves on the ground.

Aaron Roy on K157 Firestorm:
This bull has been reasonably good to right-handed riders, and to tall riders. Roy is both. Two of the past three rides on Firestorm belong to Caleb Sanderson and Beau Hill, two of the tallest riders going.

Skeeter Kingsolver on 409 Shortcut:
Kingsolver has a good draw here. Shortcut is a good bet for anyone here to get a score on, and is especially good to left-handed riders.

Jordan Hupp on 206 Clam Digger:
Clam Digger has had a long career - he's been one of the best money bulls in the PBR since 2008. He's been ridden in about two-thirds of his outs at the Built Ford Tough Series level. He's faced 38 elite-level riders, and only seven failed to get a score. He seldom produces a round win, but is more than enough bull to place in the money on.

Chase Outlaw on 510 Stinger:
Stinger has been far better for left-handed riders, and that gives Outlaw the advantage here. This is a bull who stays close to the ground and uses speed to shake riders loose. If Outlaw can keep up, he'll get a good score.

Valdiron de Oliveira on 113T Slim to None:
This bull's record is similar to Clam Digger's, although he hasn't been around as long. The top-level riders are 8-for-10 on him, and overall he's ridden more than 50 percent of the time. Oliveira should easily get a score.


15/15 Bucking Battle:

Jordan Hupp on 540 King Lopez:
Hupp moves into this round because Ryan Dirteater is out with an injury, and he inherits King Lopez, who was slated to face Dirteater. Hupp and King Lopez met in Detroit, where Hupp came down in under 3 seconds. This bull has been ridden four times in 25 outs. Two of those rides belong to Alves, who is just better than everyone else, and the other two are courtesy of Renato Nunes and Rubens Barbosa - two men who tend to stray from textbook form when they feel it necessary.

Renato Nunes covers King Lopez in Baltimore in 2012.

Stormy Wing on 156 Larry the Cable Guy's Git-R-Done:
Wing failed to ride this bull in Kansas City, Mo., and he's not the only one. Mike Lee and J.B. Mauney are the only two to get a score on this bull in 32 career outs.

J.B. Mauney scores 91.5 points on Larry the Cable Guy's Git-R-Done in Sacramento, Calif., in 2012.

Fabiano Vieira on 961 Mac-Nett's Southern Wine:
Like the first two matchups, this one is also a rematch. Vieira has tried Southern Wine twice, and did not make it to the 2-second mark either time. Southern Wine has been ridden twice this season, but he is by no means easy.

Kody Lostroh on 868 Jack Daniels After Party:
Jack Daniel's After Party is one of the better draws in this round, but he has been tough on riders this year. He's going to spin to the right, away from Lostroh's hand, but he is very rideable for riders of either hand, provided they can stay off his head. If Lostroh can stay upright, he should get a score here.

Ryan Dirteater stays upright on Jack Daniel's After Party, and scores 88.25 points in Atlanta in 2012.

Douglas Duncan on 789 Bad Blake:
Bad Blake has a very good record of putting riders on the ground, but there's nothing about his bucking style that is extremely difficult. He has good timing, and will usually go out a couple of jumps and spin to the right; he's just very good at it. He's a good draw for any rider here, but he will make them earn it every time.

Bad Blake and Valdiron de Oliveira score 88 points in New York, 2012.

Ty Pozzobon on K55 Smackdown:
Smackdown has a string of 45+ point bull scores going back to last April. It's been that long since he's been marked under 45 points by the judges. He is one of the handful of elite bulls going today, he is honest, and he is very difficult to get a score on.  Being left-handed, Pozzobon at least has a chance. I doubt we will see a righty ride this bull anytime soon.

J.B. Mauney and Smackdown team up for 92.25 points in Oklahoma City in 2012.

Guilherme Marchi on 713 Cooper Tires Grey Ghost:
This is a good draw for Marchi. Cooper Tires Grey Ghost likes to spin to the right, and Marchi doesn't like to buck off bulls who spin into his hand.

Luke Snyder on 404C RMEF Gunpowder & Lead:
This is the best draw in the round, hands down. Every one of these riders would trade places with Snyder if they could. Gunpowder & Lead is likely to pass a number of very famous PBR bulls on the all-time 90-point ride producers list this season, and he only needs eight more to reach a total of 20 for his career - something only three bulls out of over 26,000 have done.

RMEF Gunpowder & Lead takes Robson Palermo to 93.5 points in Milwaukee, 2011.

Justin Koon on 366 South Point:
This is a fairly new bull, and not only is he unridden, but if riders only had to stay on 4 seconds rather than 8, he would still be unridden.

Austin Meier on 57 Shamoun:
Shamoun was ridden in each of his first two Touring Pro Division outs way back in 2010, and since then he has bucked off 20 riders in a row, including Chris Shivers, Mauney (twice), L.J. Jenkins, Marchi (twice), Snyder, etc. In a sense, Meier is just the next victim. On the other hand, Meier's theme for this year seems to be breaking unridden streaks, so this promises to be an epic battle.

Shamoun bucks off Caleb Sanderson in New York in 2012.

Renato Nunes on 708 Delco:
Nunes has faced Delco twice this year and has two paychecks to show for it. Deco has been ridden seven times in his career, resulting in four round wins, and three second-place finishes.

Renato Nunes scores 91.5 points on Delco in New York, 2012.

L.J. Jenkins on 601 Shepherd Hills Trapper:
Jenkins faces a tough task here. Trapper is not always impossible to ride, but sometimes he can be. Even on a normal day, he is not likely to let a right-handed rider get around the corner, much less to the whistle. If he bucks like he did when Meier rode him in Sacramento, Calif., Jenkins has a chance.

Austin Meier vs. Shepherd Hills Trapper, 92.25 points, Sacramento, Calif., 2012.

Silvano Alves on 654 Mulligan Man:
Mulligan Man has faced 41 riders in his career, and only two have earned a score. Alves is one of the two. They met at a Touring Pro event in Nebraska in 2009 - he was one of the first bulls Alves faced in the U.S. It's been over a year since anyone has earned a score on Mulligan Man.

Marco Eguche on 5081 Highway 12:
Due to his talent for bucking off the top riders, Highway 12 is ranked among the 100 most difficult bulls to ride in PBR history at this point in his career. Eguche is having a good year, but he's got a tough bull to ride in this round.

Highway 12 bests Ryan McConnel in Sacramento, Calif., in 2012.

Valdiron de Oliveira on 781 Asteroid:
This is obviously the marquee matchup of the night. The odds are with Asteroid on this one. He's not a perfect fit for Oliveira's style, but Oliveira does have a way of weathering the storm on a lot of bulls who give other guys trouble.  This will be a test for both rider and bull, and is very representative of what the PBR was originally designed to create - the best riders in the world against the best bulls in the world.

Justin Koon goes 6.74 seconds on Asteroid in Houston.
