The Bucks extended Andrew Bogut's contract through the 2007-08 season on Thursday.
They exercised the third-year option on the 7-foot center's deal. The Bucks picked Bogut first overall last year.
"We drafted Andrew last season with the expectation that he would be a part of this franchise for a very long time and this is just another step in that process," general manager Larry Harris said in a statement.
