Iowa also was represented on both teams, Reggie Evans and Cara Consuegra receiving honorable mentions.
Tinsley, a ball-handling whiz with quick hands, led Iowa State to its second straight regular season Big 12 championship.
He became the team's leader after Marcus Fizer skipped his senior season to turn pro and Tinsley responded by leading the Cyclones in scoring and playing his best when the most was a stake.
Tinsley is averaging 14.5 points, six assists and 2.5 steals. He'll lead the second-seeded Cyclones against Hampton in the NCAA West Regional at Boise, Idaho on Thursday night.
"When you look at the games when we really had to have them, Mississippi for instance, he went to work," Iowa State coach Larry Eustachy said. "It goes on and on. At Kansas, he went to work late in the game. When we need him in the big games, he gets it done."
Tinsley was the leading vote-getter on the second team and was just 13 votes short of making the first team. Fizer made the first team last year.
