Dustin Ackley took batting practice at Safeco Field for the first time on Monday. "That first swing, I didn't know where the ball was going to go or if I was even going to hit it," said Ackley. "It was a relief." Ackley was in Seattle to officially sign his five-year major-league deal with the Mariners, worth at least $7.5 million. Ackley was the number two overall pick in the 2009 MLB Draft.
