LAS VEGAS — Kody Lostroh won a $1 million prize for his first Professional Bull Riders world championship Sunday, and JB Mauney took the last round to become the only rider ever to cover all eight bulls in the world finals.

Lostroh finished the season with total earnings of $1,601,624. He came 0.53 seconds away from also successfully riding all eight of his bulls at Thomas & Mack Center, but was bucked off Voodoo Child in 7.47 seconds.

One rider earlier, Mauney scored 93.75 points on Black Pearl to secure his first finals aggregate title with 715 points. He earned $250,000.

Lostroh clinched the season title with a third-place ride in the seventh round. He held the top spot for the last 20 events of the regular season and eight finals rounds, finishing with 16,640 points.

Mauney was second with 16,046, and 2008 world champion Guilherme Marchi, who was bucked off in five of the seven rounds, was third at 11,970.75.

Lostroh was second in the aggregate with 624 points, and Valdiron de Oliveira, who also covered seven bulls, was third at 618.5.

In the championship round, McKennon Wimberly on The Game and Shane Proctor on Necessary Evil were the only other successful riders. They tied for second with 90s.

Earlier Sunday, during the seventh round, Mauney, de Oliveira and Lostroh each covered their seventh bull in a row. Lostroh finished third with a 90 on SoulJa Boy, de Oliveira had an 88.5 on Far West, and Mauney an 86.75 on Smack Down.

Aaron Roy won the seventh round with a 91.75 on Top Notch.

Lostroh failed in his bid to become the second rider to win the season championship and finals average during the same year. Mike Lee accomplished the feat in 2004.

Cody Nance won the 2009 Daisy rookie of the year title, finishing 26th overall with $147,385. Caleb Sanderson was second with $104,432.

Code Blue won the 2009 PBR bull world title. He clinched the crown in the championship round when he bucked off Meier in 6.5 seconds and earned a score of 46.75. Code Blue's finals three-round total was 140.75. Voodoo Child was second at 139.5, and Big Tex third at 138.75.
