TAMPA, Fla. (AP) _ Olympic diver Bruce Kimball pleaded guilty today to drunken-driving manslaughter in the deaths of two teen-agers Aug. 1 and could receive up to 22 years in prison at sentencing Jan. 30.

Prosecutors said the 25-year-old athlete had a blood-alcohol reading of 0.2 percent, twice the legal limit, the night his car plowed into a group of teen- agers at a hangout in Brandon, killing two and injuring four shortly before the Olympic trials.

The athlete pleaded guilty an hour into his trial today to two counts of manslaughter while driving under the influence and three counts of causing great bodily injury while driving under the influence.

Kimball competed in the Olympic trials but failed to make the U.S. team.

Assistant State Attorney John Skye said a witness at the accident scene saw Kimball get out of the car, beat his fist on the ground and say, ''There go the Olympics.''

Killed in the accident were Robbie Bedell, 19, and Kevin Gossic, 16.
