Missouri Tiger sophomore Blake Irwin won his first career Big 12 title during the final day of the 2010 Big 12 Outdoor Championships on Sunday at Walton Stadium in Columbia. Irwin joined Nick Adcock as Big 12 champions, who won the Decathlon on Saturday.

Irwin finished in 1:48.40, more than half a second ahead of the next second place finisher. Irwin’s time of 1:48.40 in the event is a personal-best in the event and ranks him 21st nationally and eighth in the west region, qualifying him for the first round of the NCAA Championships, which will be held in Austin, Texas, on May 27-29.

Adcock claimed the Big 12 Decathlon title with a personal-best score of 7,704 points, narrowly edging teammate Lars Rise who was second in the event with 7,695 points on Saturday. It was so close between the two teammates, that it all came down to the final 1500 meter race. Adcock told mutigers.com, “I knew Lars had to beat me by about a second and a half (heading in to the race),” Adcock said after winning. “He was going to try to run pretty quick today, but with the weather conditions he couldn’t. We got out well on the first lap but the second lap was slow. I was just going to stay right with him or in front of him. When he passed me I had some kid on my front left and got blocked so I had to follow around. Then I just sat right on him. On the last 100m I pulled ahead and he made a surge and I still had a lot left. I didn’t go all out on the 1,500m run, but I did what I had to do.”

With the decathlon title, Adcock becomes only the second Big 12 athlete to sweep the Big 12 Indoor Heptathlon and Big 12 Outdoor Decathlon titles in the same season. It also adds to an accolade-filled season for the Tiger senior who said that it was the first time that he was able to smile after a decathlon.

In all, the Tiger men and women each earned 10th overall in the team competition with 44 points and 24 points, respectively. Texas A&M ran away with the women’s championship after scoring 157 points, 55 more than second place finished Nebraska. The Nebraska men, claimed the men’s championship with 118 points, just four ahead of second-place Oklahoma.
