Last year the Phillies knew that their pitching rotation was going to receive some help. They had Duckworth and Padilla in the minors. Both came up at the end of the year last year. This year Padilla has had the better numbers year, but both will continue to do well with the Phillies. If the Phillies bats can come alive like they did last year, then both of these starters should have solid years. With Robert Person ailing and the inconsistency of Randy Wolf, Padilla might emerge as this team's unoffical ace.
However, if another team is going to offer you a veteran stud pitcher in exchange for Padilla, then it is worth thinking about. Like all pitchers, hitters will figure him out, and he will have to make adjustments. However, Padilla has alot of upside to him, so I would just sit back and enjoy your pitcher.
