CHICAGO -- Cubs manager Dale Sveum and hitting coach James Rowson were happy Brett Jackson accepted the drastic changes they suggested to the young outfielder's swing during a workout in November in Mesa, Ariz. Jackson was promoted to the big leagues Aug. 5 despite leading the Pacific Coast League with 158 strikeouts. He batted .175 in 44 games with the Cubs.
Sveum said it may benefit Jackson that he hit "rock bottom." The outfielder, who was the Cubs' first-round pick in 2009, has been hitting more this offseason than in the past. He is still expected to open at Triple-A Iowa.
