Greg Vaughn's middle name isn't "You Suck!" but Padres fans sure made it sound that way at Qualcomm Stadium, where the once potent slugger ran up Buddy Biancalana-sized numbers last season. At his best, Vaughn, 32, is a 30-home-run guy who, during his seven years with Milwaukee, regularly launched lunar shots. At his worst, he is the '97 Edsel, a player who batted just .216 with 18 homers and a measly 57 RBIs. With improved pitching, the Padres are talking pennant, but for that to happen, they need to see Vaughn's slugging percentage jump to .493—up 100 points from last season.
