The Long Beach Office of the Company Comprehensive Drug Testing doesn't get a lot of drop-in visitors.

But on a cool day of April 2004, group of 11 appears and they're armed.

Special Agent Jeff Niewitsky leads to charge.

Everyone remain where you are. We're federal agents and I have a search warrant to collect the urine samples and test results for these 10 major league baseball players.

Agent Niewitsky hands over the list. Gary Sheffield, Jason Gianbi, Barry Bonds, forget-ed Agent Niewitsky.

You have no right to seize any of our samples or our data. I think I do. We subpoenaed them months ago and if you don't hand them over, I'll be shutting you down today.

Now we made a deal with the federal prosecutors yesterday. They agreed to delay the subpoenas as long as we agreed to preserve the samples and the data.

So thanks for stopping by. Yeah, except I went before a judge this morning and he gave me the search warrant.

I'll have to call our corporate headquarters. No problem. We'll wait.

Jeff Niewitsky is used to waiting. He's been in a legal tug of war with the owners and the players union for months.

At the center of it is comprehensive drug. The company Major League Baseball uses to drug test their players.

He wants the results for all the players for 2003 in the first year of baseball's new, more rigorous testing program.

There's only one problem. The owners have vowed to fight it all the way to the Supreme Court.

So Niewitsky files another subpoena limited to the 10 players connected to Balco. If he gets those samples, he can bring down Balco's founder, Victor Conti.

When the union files a motion to quash that subpoena as well, the government makes a deal. They'll agree to let the matter resolve in the courts as long as the samples are preserved.

Niewitsky doesn't like that deal, so he makes an end run around it.

First thing this morning, he went before a judge and convinced him that the samples are in danger of being destroyed and got his search warrant for the Balco 10.

After a series of frantic calls between the lab and their lawyers, the company finally hands over the test results for the Balco 10.

But by then, one of Niewitsky's agents has discovered a master list on the company's computers.

It contains the drug test records of every major league baseball player. Niewitsky sees us the data.

It's a huge victory for him. He walked in demanding test results for 10 players and walked out with records for 1100.
