UPDATE 11:59 a.m. ET: After his picks went 29-3 the first two full days of the NCAA tournament, President Barack Obama wasn't so fortunate on Saturday.

The president lost one of his Final Four picks when Pittsburgh, the No. 1 seed in the Southeast Regional, lost to eighth-seeded Butler.

Obama also missed picking Wisconsin to reach the Sweet 16. The Badgers beat Obama's pick, Kansas State, 70-65, in Tucson.

Including the loss of Louisville on Thursday, the president has seen three of his Sweet 16 picks go down.

If you put President Barack Obama's bracket picks in your office pool, there's a good chance he has jumped into the lead after the second round of games.

The president's second-round picks went 29-3 the last two days -- including 15-1 on Friday -- to rank in the 100th percentile in ESPN's Tournament Challenge game.

Obama's only loss Friday was his pick of Georgetown after the Hoyas lost to No. 11 seed Virginia Commonwealth. On Thursday, he incorrectly picked Louisville and Michigan State.

But with his 29-3 mark, Obama ranks 492nd out of nearly six million brackets that were submitted on ESPN.com.

Of the six million, not one bracket in the ESPN Tournament Challenge correctly picked all 32 games. Only 19 of them went 31-1.

Obama picked all four No. 1 seeds -- Ohio State, Kansas, Pittsburgh and Duke -- to reach the Final Four with the Kansas Jayhawks cutting down the nets in Houston.
