The Cubs have had some "can't miss" prospects before that somehow missed badly, including Corey Patterson, Felix Pie and Brooks Kieschnick. Jorge Soler knows the history and doesn't want to fall into that category. "I want to do everything on the field to do better for the Cubs," he said. Soler showed what he can do in his first at-bat in an intrasquad game Thursday at HoHoKam Stadium, homering off Nick Struck, one of the better pitching prospects in the organization. "He wants to be different," coach Franklin Font, Soler's translator, said. "He wants to leave his mark for Chicago." Soler drew a walk in his second at-bat, and made a nice catch in left field. But what really impressed manager Dale Sveum was Soler's bat speed. "That's what we've talked about all the time," he said. "That's the kind of stuff that's on the radar now. The guy following him up (Javier Baez) had some pretty good bat speed through the strike zone, too, as well as (Junior) Lake. There are some guys on that radar now who possibly can be impact players someday." Baez was a "little shaky" at shortstop, Sveum said, and needs to work on changing "some instinctive stuff." All in all, it was a good chance for the kids to get a little comfortable before the start of Cactus League play Saturday in Tempe, where the Cubs meet the Angels. Garza watch: Matt Garza said Cubs physician Stephen Adams told him to "relax and enjoy it a little bit because this is probably the last time you'll be off." Garza is taking a week of rest after tweaking his left side while throwing his first live batting practice session Sunday. "He's not 100 percent symptom free, but really close now," Sveum said. "I think we lucked out on that one. It wasn't that big-time rib cage (pull or an injury) that can take forever."
