DALLAS -- The Toronto Blue Jays turned their attention to offense on Wednesday night, acquiring first baseman Lyle Overbay from the Milwaukee Brewers for right-hander Dave Bush, outfield prospect Gabe Gross and Triple-A left-hander Zach Jackson. The Blue Jays, expanding their payroll from $45 million to $75 million next season, have been one of the most active teams in baseball this offseason. They already added starter A.J. Burnett and gave closer B.J. Ryan a five-year, $47 million contract that is the richest ever for a reliever. "We added two good arms and a bat we really wanted," Toronto general manager J.P. Ricciardi said. "We'd like to get one more bat." Overbay, a left-handed hitter who is eligible for arbitration, batted .276 with 19 homers and 72 RBI this year. His departure clears the way for top prospect Prince Fielder to take over at first base in Milwaukee. "He'd better be ready now," Brewers general manager Doug Melvin said with a smile. "He [Overbay] knew it was going to happen. He's seen Prince play. He knows what kind of player he is. Now he's going to get a chance to have a good career."
