With Michael Cuddyer gone and Josh Willingham signed, the Twins still have three potential areas to add players before spring training. They need outfield depth, a starting pitcher and multiple openings in the bullpen.
According to current news reports, they are now making a renewed effort to sign Jason Kubel. Willingham is currently slotted as the Twins right fielder, but he has very limited experience there. His range is not good to begin with and a less than stellar arm will be exposed in right field. That was probably at least part of the reason the Twins kept their offer to Cuddyer active after signing Willingham. Kubel could fit into that spot along with some DH duties.
Right now, Ben Revere is slated to be the Twins left fielder. But, while Revere likely has a bright future, he may or may not be ready to play every day. With Kubel in the outfield, Revere's playing time can match his performance with Kubel, Willingham and Doumit sharing the DH duties when Revere is in the outfield.
The most obvious need the Twins have is for another starting pitcher. With Slowey gone and Duensing slated for the bullpen, Pavano, Baker, Liriano and Blackburn are the only experienced starters. Swarzak is a potential 5th starter and there are some minor league players who will get a look. But that really isn't how you want to start spring training. The problem is that starting pitchers are not cheap. They may be able to grab someone who was non-tendered, but more likely a quality starter is going to require giving up some value in a trade.
They have a LOT of players signed who can fill out the bullpen. But the top three spots right now are Capps, Perkins and Duensing. They really need a right handed setup guy to pair with Perkins in the 8th inning. With Swarzak and Duensing working the 7th then the bullpen could be a team strength. But without another solid pitcher to get to Capps, the bullpen looks very weak. Its going to be a very long season if we see Capps warming up again in the 8th inning the way we did last spring.
