The only breakout in the career of second baseman Wilton Guerrero thus far came in 1997, when he was a member of the Dodgers and cork was embarrassingly discovered in his broken bat. Since being traded to the Expos last July, the 24-year-old older brother of Vladimir Guerrero has sworn off all hitting aids except his newfound biceps. Wilton is now a hard 188 pounds, in anticipation of the 600 at bats he'll receive in the leadoff slot. In addition to helping translate for Vladimir, Wilton will be expected to run and to cultivate both his bunting and patience (22 walks in 761 career at bats). "He's not Vladimir," manager Felipe Alou says, "but we think he'll be an excellent offensive player."
