The Twins have officially announced that they have agreed to terms with reliever Joel Zumaya on a one-year contract. We reported earlier in the week that the deal is worth $800,000 with the chance to earn another $900,000 in incentives.

Zumaya had to pass a physical exam before the club made the deal official.

The Twins, in desperate need of bullpen firepower, are rolling the dice that Zumaya, who routinely hit 100 miles an hour with his fastball but has dealt with injuries up and down his talented right arm, can stay healthy and provide the Twins with an advantage late in games.

Zumaya is scheduled to speak to the media via conference call at 10:30 am Thursday.
