Commissioner: MLB monitors IT systems used by league office, teams

OAKLAND, Calif. -- Commissioner Rob Manfred said Friday that Major League Baseball has a system in place for monitoring attacks on computer systems used by teams and the league's office.

Speaking before Oakland's home game against the Los Angeles Angels, Manfred did not delve into the details of the FBI's investigation into the St. Louis Cardinals for allegedly hacking into a database operated by the Houston Astros.

Manfred did say he was confident no other incidents like this one had taken place before.

"We monitor, centrally, all unauthorized incursions into the IT systems in the industry," Manfred said. "We do that because, most of the time, you're talking about somebody from outside the business, right?

"We had pretty good information on what goes on in that area and we have no reason to believe that there's ever been an incident like the one that is being ... again, I want to be really careful with this ... investigated."

Major League Baseball has said it will evaluate additional steps once federal law enforcement officials complete their investigation. A person familiar with the investigation has told the AP that federal authorities are looking at whether the Cardinals were to blame for what the league called a "breach" of the Astros' database.

Manfred did not offer any further comment on the situation, but touched on a variety of other topics.

The commissioner spent most of his time discussing the stadium situation in Oakland. He said it would be impossible for the A's to build a new stadium at its current site if the NFL's Oakland Raiders build one there, too.
