Going into Monday's openers most commentators seem to think the Twins bullpen is its primary weakness. There is some truth in that, but not as much as you might think. The Twins have one of the best closers in baseball in Nathan and three proven setup guys in Crain, Guerrier and Ayala. What none of those three are is a dominant 8th inning guy. They also have a solid lefty in Breslow. While not as strong as it has been in some past years, the bullpen is really unlikely to be a major weakness.
I think there are couple places where the Twins may not be as good as they appear in the many preseason evaluations - including my own:
All four of the regular outfielders, Cuddyer, Span, Gomez and Young have question marks about what can be expected from them. I like all four of these guys individually, but I think it is very unlikely all the answers will be positive. My guess is that the Twins will lose a few games before they sort that out.
Casilla is still young and he struggled toward the end of last year. To some extent, I think we should expect that to continue. I don't think he is going to lose his job, although that is possible, but more likely that he will not be a huge plus as a number two hitter and people will start complaining about fielding miscues again.
Mauer will come back, but he is not going to be fully ready when he does. And having Redmond play every day at the start of the season is going to leave him worn out. The result, at the end of the year, is going to be much less offense from the catchers than the past couple years.
The expectations here are just too high. Baker going on the DL ought to be a wakeup call. Its likely at least one of the top 5 starters will fail or get injured. Another one will likely be just barely adequate for a large part of the season. The Twins pitching will still be good, but it is not likely to be one of the best rotations in baseball, as some fans and sports writers seem to believe.
