Twins add Meyer, Rosario, Sano, and Wheeler to the 40-man roster

Coming into this morning, the Minnesota Twins had four spots open on their 40-man roster. They added Alex Meyer, Eddie Rosario, Miguel Sano, and Jason Wheeler, removing no one. As we discussed on Monday, Meyer, Rosario, and Sano were all guaranteed adds. Wheeler we tabbed as one of the second tier players who could contend for a spot, but a number of other players have been left exposed to December's Rule 5 draft.

Sean Gilmartin was the player many people expected to be protected, but by keeping Wheeler the Twins have chosen upside over high-floor depth at Triple-A. Gilmartin is a left and will be just 25 in May, but his peripherals profile him as a back-of-the-rotation arm in the most optimistic of scenarios. Wheeler, who turned 24 in October and is also a lefty, but his command looks like it's a shade better. Oddly enough, both pitchers have only allowed 29 home runs in roughly 80 minor league starts.

Besides Gilmartin, who seems likely to be taken in the Rule 5, players like Niko Goodrum, Tyler Jones, Cole Johnson, and 2011 first-round pick Levi Michael have been left exposed. Goodrum is the least likely to be taken of the group, as he's unlikely to stick on anyone's 25-man roster all season. Jones and Michael aren't too far in front of him. Johnson, however, also might look like an attractive add for someone willing to take a flyer.

Minnesota added the most important players, and considering that all three of Meyer, Rosario, and Sano are projected to be big parts of the club's future, that's pretty exciting!
