The Cardinals have a very potent shortstop in Peralta, talent in CF Bourjos, and an all-around offensive line-up. Their rotation is top-notch, and the bullpen should continue to click with the return of Motte. Their chances of winning this year are good. They'll have to deal with tough opponents, but their improvements in the off-season will be enough to clinch a 12th title.
The 2013-2014 St. Louis Cardinals won't win the World Series this year. They won a couple seasons ago, but this team isn't built to dominate its league right now. They have great pitching and a potent lineup, but the St. Louis Cardinals aren't going to beat other contenders during this season.
The St. Louis Cardnials will not the the 2013-2014 world series. They lack the depth at the pitching position. Too many dangerous teams to deal with in the AL. I'm not a betting man but I would put money on Boston getting two in a row or the Yankees signing some new hitters and winning the world series.
