Matt Holliday is finally an Athletic, as the A’s announced they’ve completed the trade for the Colorado Rockies left fielder. The Rockies receive Huston Street, Greg Smith and Carlos Gonzalez.

By now you know the deal. The A’s get one of the game’s top hitters, but it could just be a one-year rental. Holliday makes $13.5 million in 2009 and then can become a free agent. Regardless, he’s a huge addition for this offense as Eric Chavez and Mark Ellis have both declared.

Holliday is scheduled to talk with Bay Area reporters later in the morning.
