Michael Tucker will be the Braves Number 2 hitter this season, which means he's got a Roseanne-sized responsibility on his shoulders. When Tucker joined Atlanta last season, he was the perfect spray hitter to bat behind the explosive and jet-propelled Kenny Lofton. That worked fine-Tucker hit .283, smacked 14 homers and stole 12 bases. With Lofton gone, however, new shortstop Walt Weiss will lead off. For the Braves to score enough runs to repeat last year's success, Tucker, who had 116 Ks in '97, has to consistently move Weiss over. To do that, Tucker must have fewer than 80 strikeouts.
