As Seth hinted in his post earlier today, it's HIGHLY likely that one of Baker/Marquis won't be on the team opening day due to outside circumstances. Hendriks is a clear choice to be called up, but I doubt the Twins want to bring him north just for a single spot start.
Looking over the waiver wire for professional veterans one name jumps out as a potential spot starter and someone who could actually stick as a very solid #5, even better: Gardy and company are familiar with him as he posted a 23-16 record and a 3.84 in a two year stretch for this team before, the man I am speaking about of course is Carlos Silva who is primed for a legitimate comeback at the still somewhat young age of 32.
Silva was misguidedly let go by the Red Sox recently, and was unfairly viewed as a scape goat in Seattle and Chicago, a trip back to Minnesota I believe would do the trick. At the very least you have a solid #4/#5 who can fill in for the first few weeks, at best perhaps he could get back to his old Twins self and post a sub 3.90 ERA and become a 200 IP #3 type pitcher, this would allow the Twins to have the flexibility to trade either Pavano or Baker at the deadline.
In addition,Silva would bring a little fire to the team and a different attitude which could help out the clubhouse which recently has been viewed as complacent. Also, last year there were reports were that Mauer was 40 lbs under his playing weight, a silver lining in bringing back Carlos is that Silva could bring back "Taco Bell Tuesday" in the club house and make sure our #1 catcher eats plenty of Nachos Bell Grandes to keep his playing weight where it should be.
He can be had for the minimum, why not take a chance on Silva? These are the type of Low Risk, High Reward signings that Bill Smith basically avoided which led to his downfall.
